AND THE SOUTH POLE, FROM OBSERVATIONS MADE IN THE YEARS 1885-6 BY A. STANLEY WILLIAMS. LONDON: TAYLOR AND FRANCIS, RED LION COURT, FLEET STREET. 1898. FLAMMAM. PRINTED BY TAYLOR AND FRANCIS, RED LION COURT, FLEET STREET. INTRODUCTION. THE observations on which the present Catalogue is based were made in the course of a voyage to Australia, round the Cape of: Good Hope, and back by the Red Sea, including a stay of two months in Australia. The following is an account of the mariner in which the observations were made. Before leaving England seven groups of comparison stars were selected from " Harvard Photometry," and several hundred observations of the brightness of stars north of south declination 30 were made in the same manner as is described farther on, in order to acquire practice in the work. The star atlas made use of throughout was Proctor's smaller Star Atlas, with the addition of all the other stars contained in the large maps published by the Society for Diffusing Useful Knowledge. Nearly all the stars con- tained in Lacaille's original Catalogue of 1942 stars and lying south of 30 declination were thus included. All the stars observed have been identified by comparison with the maps of the " Uranometria Argentina," with the exception of a few stars not contained in that work. The observations were made by means of an opera-glass accurately focussed. The star undergoing observation was first brought into the centre of the field, and as soon as a satisfactory impression of its brightness bad been received, comparison was made as quickly as possible with, usually, two comparison stars, one being a little brighter and the other a little fainter than the star observed. The star undergoing observation was then again brought into the field of the opera-glass and compared with the impression which had been received of the brightness of the comparison stars. This operation was generally repeated several times, until a perfectly satisfactory estimate of the brightness of the star relative to the comparison stars had been obtained, when the result was recorded. The adopted magnitudes of the comparison stars being known, the interval between any two of them was mentally divided into as many parts as there were tenths of a magnitude between them. By this means the value of a " step " was made to corre- spond with a tenth of a magnitude on the scale of the " Harvard Photo- metry." For example, the following observation of v Hydri was made on Feb. 17, 1886: v Hydri =i Canis Majoris -f 4 = ju Canis Majoris 3. This means that v Hydri was estimated 4 steps fainter than t Canis Majoris and 3 steps brighter than p, Canis Majoris, each step being equal to a tenth of a magnitude on the scale of " Harvard Photometry." The resulting - 736352 IV INTRODUCTION. magnitude of v Hydri, unconnected for absorption, is 4*9. The different stars of a group of comparison stars generally agreed closely with this value of a step,; $baugh at times, .sKght differences were noticed, due perhaps to change in 'tka* position fecgfes. o'f the stars of a group. No corrections were applied in such, cas.e.st.buib the* stars observed were recorded as being so many*^ep^ 4 "feioji:e^udttqht6jijbl\of a magnitude) brighter or fainter than each comparison star. $uch differences, however, were never considerable, probably not exceeding at most tw r o tenths of a magnitude. The seven groups of comparison stars, with the adopted magnitudes from " Harvard Photometry," are given farther on and lettered A to G. An additional or sub-group H in the constellation Crux was also formed by numerous comparisons with the stars of Groups E and F. The magnitudes according to Bailey's " Southern Meridian Photometry" are added for comparison with the adopted magnitudes of the stars in the case of this sub-group, and also the number of observations on which the adopted magnitudes depend. Although there are some differences, it has been pre- ferred to retain the adopted magnitudes rather than to use those of the " Southern Meridian Photometry," as not only were the former derived from observations made at the same time as the observations of the stars compared with this sub-group, but by so doing the present Catalogue is rendered entirely independent of the " Southern Meridian Photometry." The chief object in forming this sub-group was to prevent loss of time caused by the detached cumulus clouds, which are peculiarly characteristic of the trade-winds. When the stars undergoing observation are far distant from the comparison stars, it often happens that one or the other is hidden behind one of these clouds. But this inconvenience was in great measure averted by having the sub-group close to the stars observed. Comparison Stars. Group A. M.

This plan could not, however, be carried out completely owing to want of time. The number of stars contained in the Catalogue is 1 08 1, and the total number of observations 2812, so that the average number of observations to each star is 2'6. But a great many stars were only observed on two nights, or even one. Considering the circumstances under which the observations were made, the resulting magnitudes of the individual stars are, on the whole, in satis- factory agreement. The results are not so accordant as those contained in Sawyer's " Catalogue of the Magnitudes of Southern Stars from o to 30 Decimation, to the Magnitude 7-0 inclusive." These were based on the method of " sequences," and appear to be exceptionally accurate. But the discordances appear to be no greater than, and in fact to be of the same order as, those of the photometric measures contained in Bailey's " Southern Meridian Photometry." * It will be well to state here some of the dis- advantageous circumstances under which the observations were made. (i) Most of the observations were made on board ship, and, in addition to the inconvenience occasioned by the motion of the vessel, the rigging and sails frequently interfere in the case of a sailing ship, whilst in the case * See note on p. ix. VI INTRODUCTION. of a steamer the smoke often constitutes a still more annoying hindrance. (2) Owing to the time at- disposal being short, the observations were continued during moonlight or twilight, or under unfavourable conditions as regards clearness of the sky. (3) Variations in atmospheric absorption. (4) The frequent presence of thin local mist or vapour, often very slight and quite indefinite in outline. This last circumstance is undoubtedly the most prolific source of discordant observations. Slight local mists or vapours of this kind are only too common on or near the sea, and they were frequently so thin and indefinite, that it was often impossible to determine their presence, or whether a particular star was affected or not. As the stars undergoing observation were usually at a distance from the comparison stars, it was necessary to correct the observations for differential atmospheric absorption. In Vol. xlvii. of the Memoirs of the Royal Astronomical Society, p. 417, Pritchard gave a table showing the atmospheric absorption at various zenith-distances as determined by him at Oxford and at Cairo respectively. After careful consideration of all the circumstances, it was decided to adopt the mean of Pritchard's two results as representing most probably the average absorption in the somewhat varying circumstances under which the observations were made. The following table contains the adopted absorptions for different altitudes. Altitude. Absorption. Altitude.' Absorption, o M. M. 70 o - oi 24 0-32 60 0*03 21 0*39 50 0-07 18 0-49 45 0-09 1 6 0-58 40 0*12 14 0-69 35 0-16 12 0-83 30 0'22 10 1*04 27 0-26 This table contains of course only the average absorption, and consider- able variations undoubtedly occurred from night to night and in different latitudes. As the total amount of the correction does not, however, exceed two or three tenths of a magnitude in the great majority of cases, these variations cannot have materially affected the results. Only where the altitude was very low can there be much uncertainty as to the amount of the correction. The altitudes of the stars observed, and of the com- parison stars, were obtained by direct measurement on a celestial globe by Cary 21 in. in diameter, and the corrections were derived from these, by means of the above table, to within two or three hundredths of a magnitude. No observation has been discarded altogether, as a discordant result may always be possibly due to variation. Mention is invariably made in the notes at the end of the Catalogue whenever an observation has been rejected in deriving the mean magnitude of a star, or where one was used with reduced weight. Also the whole of the observations of a star are given in these notes whenever the extreme observations differ by more than o M> 55. All the observations have likewise been given in a large number of cases of suspected variation, or where the observations in other catalogues are discordant. Excepting in a few instances, where the obser- vations are numerous, the results are stated to the nearest half-tenth of a magnitude. There are distinct signs of a systematic difference affecting the stars observed on several nights. On 'four nights in particular the observed INTRODUCTION. Vll magnitudes are generally considerably too bright compared with other observations of the same stars on other nights. Comparing the magnitudes on these four nights with the mean magnitudes, the following table shows the number of positive and negative residuals for each tenth of a magnitude Positive Residuals. Negative Residuals. Date. 54-3* i o 12345 6 7 1885, Oct. 30 - 2 5 6 581-1- , 3 1 4 5 9 1132 I I I 1886, Feb. 28 - 6 3 15 15 12 8 2 - - I Mar. i .... i i 6 ii 10 10 3 3 - - for those cases in which the stars were observed on other nights besides the four in question. It will be seen that there is a great preponderance of negative residuals on each of the four nights. The preponderance of negative residuals is even more significant than would appear from the above table, as the mean magnitudes from, which the residuals were derived were themselves dependent largely upon observations made on the suspected nights, and the observations of each star are generally only few in number. Moreover, on a good many occasions there are three observations of a star, two of which were made on suspected nights. This still further increases the significance of the preponderance of negative residuals. After full consideration of all the circumstances, it was decided to apply the following constant corrections to the observations of these four nights : 1885. Oct. 30 1886. Feb. 28 Mar. i M. Correction = +0*2 These corrections are, if anything, too small rather than too large. Mist is noted as having been very troublesome on Oct. 30, and clouds as troublesome on Oct. 31. On Feb. 28 the sky was illuminated by very brilliant and nearly continuous flashes of lightning. There was also much haze or cloud at times. The night of Mar. i was remarkably clear, small stars being distinct almost down to the horizon. There was, however, misty cloud at times. There are traces of a similar but less marked constant difference in the observations of several other nights. No corrections have, however, been applied to any observations other than those made on the above-mentioned four nights. The comparison star employed by Bailey in the formation of the " Southern Meridian Photometry " was a Octantis ; but the brightness of this star was so checked by frequent comparisons with a number of stars of the "Harvard Photometry," that the former work ought to form a continua- tion of the latter, and the scales of the two catalogues should be the same, and this notwithstanding that the altitude of a Octautis was very low at one of the stations occupied by him. It becomes a matter of great interest Vlll INTRODUCTION. therefore, to make a comparison between the magnitudes of the present catalogue, based on direct comparison with stars of " Harvard Photometry," and those contained in the " Southern Meridian Photometry/' But first, as u certain number of stars included in the present catalogue are also con- tained in the " Harvard Photometry." it will be desirable to compare these. Tho mean difference H.P. W. from 44 stars common to the two cata- logues is o M- oo2. It would appear therefore from this, that the present catalogue on the whole accords exactly with the "Harvard Photometry," though the number of stars is too small for absolute certainty. TABLE I.

The first column of the INTHODUCTTON. IX table contains the magnitude in the present catalogue : the second the number of stars compared ; the third the unsrnoothed, and the fourth column the smoothed residuals S.M.P. W. The values in the last column were found as follows: The residuals contained in the third column were projected upon a chart in which the ordinates represent star-magnitudes, and the abscissae residuals. A smooth curve was then drawn as exactly as possible through the resulting points, and the values in the last column were read off from this. This table shows that there is a distinct difference of scale between the two catalogues. They practically agree between 2 M> 6 and 4 M *8, but the magnitudes of the present catalogue are systematically brighter than those of the S.M.P. for stars fainter than the latter value, the difference, however, only amounting to o M *i2 at maximum. There is, however, a more marked difference with respect to stars brighter than 2 M> 6, the magnitudes accord- ing to the present catalogue being considerably brighter than those of the " Southern Meridian Photometry," and the difference at maximum amounting to about a quarter of a magnitude. The mean difference S.M.P. W. is +0^04(851 stars). It is possible that the difference of scale is due to systematic error in the present catalogue, both bright and faint stars having been observed relatively brighter by W. than those of medium brightness. But it seems probable that, notwithstanding the pre- cautions taken by Bailey, there is also a systematic difference between the " Southern Meridian Photometry " and the " Harvard Photometry." In other words, that the former is not exactly a continuation of the latter. Out of 64 stars common to these two last-mentioned catalogues there is a decided preponderance of + residuals, the mean difference S.M.P. H.P. being -fo Mt o5*. This is almost identical with the mean difference S.M.P. W. ( + o M 'O4). The number of stars common to the " Southern Meridian Photometry " and " Harvard Photometry " is not large enough, however, to render any conclusion as to this quite certain. Table II. contains the results of a similar comparison between the present catalogue and the " Uranometria Argentina." The differences are here much more considerable, as might be expected, seeing that the scale of the " Uranometria Argentina " differs largely from that of the " Harvard Photometry." Between 2 M '8 and 3 M *4 the two catalogues nearly corre- spond, but for brighter stars the magnitudes in the present one are brighter than those in the " Uranometria Argentina," the difference increasing nearly regularly with the increase in brightness. Between 3 M< 4 and 5 M *8 there is a similar nearly regular increase in the brightness of the stars according to the present catalogue. But beyond 5 M *8 a sudden and very remarkable change takes place in the opposite direction, the magnitudes of the present catalogue becoming fainter again relative to those of the " Uranometria Argentina," until at 6 M< 9 the two catalogues again coincide. Between 5 M> 8 and 7 M> 2 this remarkable change takes place at an exactly uniform rate. Since traces of a similar change are apparent in Table I., it is probable that it is peculiar to the present catalogue, and is due to some form of systematic error. * The sum of the residuals S.M.P. -H.P. without regard to sign is I3'i8, from 64. stars. For 44 stars in like proportion this would be 9'o6. The actual value from the 44 stars employed in the comparison between the present catalogue and the " Harvard Photometry " is exactly 9*06. This confirms the statement, made on p. v, based on the general impression received in making the comparison between W. and the S.M.P., that the discordances of the present catalogue are of the same order as those of the " Southern Meridian Photometry. In other words, that the two catalogues are- of about equal accuracy. I INTRODUCTION. TABLE II. Comparison with U.A. Mag. W. No. of Stars. U.A. W. * No. of Stars. U.A. W. Unsmoothed. Smoothed.

The observations of 1885-6 are given in the notes at the end of the Catalogue without any reference letter, and usually without the year in which they were made. No difficulty will be experienced from this latter omission, since the months of October, November, and December refer to 1885, and January, February, March, and April to 1886. The colors of some of the stars have been added in the last column of the Catalogue. They were observed either with the opera-glass or with a 2|-in. refractor. One variable star, V Puppis, was discovered in the course of the obser- vations. A list of 13 stars, probably variable*, has also been published in the Astr. Nach. Nos. 3440, 3450. The observations of these stars are so discordant that some at least of them will certainly turn out to be variable. Various other instances of probable or possible variation are referred to in the notes at the end of the Catalogue. * Nos. 36, 174, 180, 390, 460, 482, 563, 689, 732, 735, 859, 996, and 1019.

On Nov. 27, 1870, it was estimated brighter than rj Canis Majoris. A. W. Eoberts, from his observations in 1891, rather questions the reality of variation, and suggests that a change in the color of the star observed by him might be the cause rather than the conse- quence of an apparent change in magnitude (Memoirs B. A. A. i. 56). The range of variation observed by him in 1891 was from 27 to 3-1 (on the scale of the U.A.). Again in 1892 the star was observed on 13 nights by Eoberts, and on each occasion its magnitude was slightly fainter than that of rj Canis Majoris, or about 3-0 on the TLA. scale (Journal B. A. A. iii. 371). The observations given above show, however, almost beyond doubt that 30 A CATALOGUE OF THE MAGNITUDES OF loSl STARS. the star is really variable, though very likely variation takes place in in irregular fashion, like that of a Orionis. It will be seen that all the observations are in satisfactory agreement with the exception of the two made on Dec. 29 and Dec. 31. These two observations differ by as much as 0*85 and 0-55 respectively from the mean magnitude, and since there are two consecutive observations, accidental error is highly improbable. And a careful examination of the original record fails to reveal any circumstance, such as the presence of twilight or moonlight, that might have affected the results. Clouds were troublesome on Dec. 29, but the night of Dec. 31 was re- markably clear and free from cloud. Usually the star was rated as about equal to 17 Canis Majoris, but on Dec. 29 it was recorded as 0*9 mag., and on Dec. 31 as o % 6 mag. fainter than that star. It seems pretty certain therefore that TT Puppis suffered a temporary diminution in brightness at the end of 1885, amounting to at least three fourths of a magnitude. The S.M.P. measures are also dis- cordant ; and a recent series of observations by E. E. Mark wick at Gibraltar in 1896-7 tend strongly to confirm variability, there being a difference of 1*1 mag. between the extreme observations {English Mechanic, vol. 66, p. 384). TT Puppis is a very finely colored star, and in 1891 Eoberts states that he observed " slight, but still very apparent, variation in its ruddy color." The following observations of 1885-6 also strongly suggest variation in color. 24. Dec. n. Nov. 1 1 . Very fine orange. 13. Pale red. 14. Orange. 15. Reddish orange. Reddish yellow.

The mean of the above two observations differ by as much as 0-6 mag. from the S.M.P. value. Moreover the S.M.P. measures are very discordant, the residuals differing by more than a NOTES. 37 whole magnitude. There can be no doubt, therefore, of the variability of this star. 680.

The magnitudes of the 4 stars y, , a, and /3 Coronae Aust. according to the observations of 1886 are all lower than the S.M.P. values. It is improbable, there- fore, that the difference in this case is due to variability. 933, 934, 935. The following are the observations of /3 l , /3 3 , and a.

The observation was made on Feb. 14. Gould remarks that the star " is of a remarkably blue color. Our estimates of its magnitude range from 3-6 to 4-2." The S.M.P. measures are also discordant. The star was examined on Feb. 16 and 17 with the 2|-in. refr., the color on both nights being recorded as white. 945. The observation was made on Feb. 14.

Variability seems certain since these two accordant observations differ by 0-7 mag. from the S.M.P. value, whilst the S.M.P. measures are themselves very discordant, the residuals differing by nearly a whole magnitude. B. made it 5, H. 6. 998. Oct. 30, 5-65 ; Oct. 31, 5-75. The S.M.P. measures are not very accordant. B. made it 6 mag., H. 6*5. 1000. The H.P. mag. is 4*23. 1001. Oct. 13, 4-7; Oct. 30, 4*65; Oct. 31, 4-6. As these differ con- siderably from the S.M.P. mag. the star may be variable, especially since three accordant observations of t Piscis Aust. made on the same nights agree almost exactly with the S.M.P. value of that star. B. and H. both give the mag. of Piscis Aust. as 5, Argelander and Heis both as 4. The H.P. mag. is 5-05. 1004. Oct. 15, 5-4; Oct. 30, 5-2; Oct. 31, 5-2. 1009.

Oct. 30, 5'i; Oct. 31, 5 '4. Notes to both observations state that estimation was difficult on account of the proximity of the star to /i 1 Gruis. Neither B. nor H. observed it. 1019,20. The following observations relate to the combined light of n l and 7T 2 Gruis : Oct. 15, 5-1 ; Oct. 30, 4-45 ; Oct. 31, 4-95. The U.A. magnitudes of the two stars are 6"j and 5-9. In the map made use of in 1885 there is only a single star marked ?r in the place of these stars. There is no mention of duplicity in the observation of Oct. 1 5, but a note to that of Oct. 30 states that " it is a close double star in the opera-glass, the preceding component being slightly tho brighter"; and another note on Oct. 31 says, "two stars close together and equally bright considered as one." The above notes make the relative brightness of the two stars quite different from what it is in the U.A., so that one of them must certainly be variable. The magnitude of Tr 2 is given in the S.M.P. as 5-81, that of ir l not having been measured, and the addition of a companion of the same brightness would increase the brightness to 5-06, which agrees very closely with the observed magnitude on Oct. 31. It is evidently Tr 1 , therefore, which is the variable star. Lacaille made the magni- tudes of Tr 1 and Tr 2 7 and 6 respectively, but in the Brisbane Catalogue they are both given as 6. Gould remarks that "the color of ir l Gruis is a deep crimson, while its neighbor TT' is conspicuously white." 1026. The following are the observations of L. 9181 and L. 9183 : L. 9181. L. 9183. M.

The two accordant observations of L. 9181 differ so largely from the S.M.P. value that the star would appear to be variable, though this is rendered less likely from the fact that the two accordant observations of L. 9183 also differ considerably from the S.M.P. magnitude. 1028.

The H.P. mag. of y is 4*29, and of t) 4'43, which reverses the order of brightness of the stars as shown by the U.A., S.M.P., and the present Catalogue. Argelander, Heis, B. and H. all make the two stars the same magnitude. The evidence in favour of variation does not seem very strong, though there may be slight fluctuations in relative brightness. 1046. The H.P. mag. is 1-26. 1051. An observation 5-4 on Feb. 28, marked " rough est. owing to cloud," has been rejected. 1055. Feb. 21, 5*55 ; Feb. 28, 5 '3 5. The S.M.P. measures are discordant. 1056.
