INTRODUCTION The observations now finally published in this volume were rqade by Professor Peters, during the decade beginning in 1860, with the i3-inch Spencer refractor of the Litchfield Observatory of Hamilton College, at Clinton, 1 N. Y. They were prepared in tabular form by their author for publication, and his 412 pages of manuscript tables, with some minor omissions, served the printer as copy. It is supposed that Dr. Peters also wrote an introduction describing the methods of observation and reduction, but unfortunately this seems to have been hopelessly lost. The fourteen original notebooks entitled, " Observationes astronomicae originales Maculae Solis," are preserved in good condition. These contain for each date a pencil sketch of the appearance of the spots on the sun's disk (of diam- eter about ii cm), presumably copied from the larger sketch made on the projection screen. They also record the readings from the chronograph sheets and the declination scale, together with the clock error. There were also preserved the 312 sheets of reductions, representing the logarithmic work involved in deriving the heliographic latitude and longitude. These also show what reduction quantities, calculated from the adopted ele- ments of the sun's rotation, were used each day, but they do not state whence the elements were derived. The author doubtless computed tables for his own use in the work, but they have not been found. Investigation has shown that he employed for the longitude of the node and the inclination the values derived by Carrington from his long series of observations, and recommended by him for future adoption, viz., N = 734o' for 1850, I = 7 15'. Dr. Peters employed a different period and a different epoch from those of Carrington, and reckoned his longitudes in the oppo- site direction. In order to give, in the author's own words, a general description of the procedure followed in the observations, the editor has translated the following article by Dr. Peters, which appeared in Band 64, pp. 209-213 (1865), of Astronomische Nachrichten. "In the observations which have been made here since May 1860 on the phenomena of the solar surface, the principle was adopted of measuring as far as possible everything of a measurable character that appeared on the solar disk. Therefore in the first instance the co-ordinates were determined of all the visible spots on each date, and these determinations were extended to all the isolated dots and the principal members of groups; also, indeed, to many faculae of definite form. For spots of considerable extent the dimensions of the umbra and penumbra were micro- metrically determined, generally in the direction of declination and right ascension. An accurate sketch was always prepared before the observations and was a necessary auxiliary, partly for convenience as a reference map during the observations and partly for the comparative study both of the changes in the forms of the spots and the arrange- ments of the components of the groups, as well as of the intensity of the outbursts and their relative positions and sequence. In the winter months observations were made on every favorable day; but in summer, when fair weather can be more safely counted on, every second day was made the rule, inasmuch as this was in general suffi- cient for keeping the spots under watch in their different stages; and, moreover, the use of the refractor for the obser- vations at night always required a somewhat disturbing exchange of the attachments at the eyepiece. " For the observation of the sun the image was projected on a screen which, firmly attached to the refractor, shared in its motions. At the lower end of the large tube of the telescope two wooden rings were put on at some distance apart; each having four corresponding holes through which wooden rods, only slightly elastic, projected about one and a half feet. The projection board was fastened in notches cut in these rods at the same distance from the eye- piece, and was held in place by the springing of the rods. This not only assured the perpendicularity of the plane of projection with respect to the optical axis but it also prescribed that the distance of the plane of projection from the eyepiece was always the same when the latter was drawn out to a definite mark corresponding to the sharpest image. To the board was attached a rather stiff sheet of paper on which had been drawn two systems of parallel lines crossing each other at right angles. A single pin, passing through the center of these lines, attaches the paper at the point where the center of the image of the field of the telescope falls. By turning the sheet around the pin, the lines can thus be made parallel to the directions of declination and hour angle. It is only necessary for this pur- pose to let the sun's limb, or any distinct spot, run across parallel to one of the system of lines, preferably along 'Latitude -43 3' 17" Longitude = 5 h i m 37*5 W. iii iv Introduction the central line. Since the angular distances from the center are projected toward the tangent, all points which transit describe hyperbolic curves. Thus we have a network of declination and time threads. For measuring differences of declination the central vertical line is graduated like a scale, and since the field of view permits the whole solar image to be seen, the scale-reading can be expressed in seconds of arc with the aid of the known apparent diameter of the sun. As one division has a linear value of inch (with an angular value of about 23"), the tenths, and some- times the twentieths, can readily be estimated. The differences of right ascension are measured by the diurnal motion with the aid of a chronograph. In order to avoid a correction which would arise from the projection above mentioned upon the plane, the transits were so arranged that use was made either of the line passing through the center of the field or of symmetrically situated pairs of lateral threads. " The eyepiece used is a so-called negative one of the Huyghens form, having two plano-convex lenses with focal lengths of 3.90 and 1.75 inches. The magnification is approximately 75, and the field of view is 38', so that it embraces on each side 3' more than the whole solar disk. The eyepiece is drawn out i . 45 inches in order to make the image distinctly visible at the distance of the projection board from the eye lens 15.43 inches. The actual mag- nification of the image is here about 140 times, or the number which we obtain if the magnification given above is multiplied by the quotient of the distance of the table divided by the distance of distinct vision (7 to 8 inches). " Further explanation is required of the conversion of the scale-distance into arc whereby the distance in declina- tion of a spot from the sun's center is measured. On account of the size of the angles under which the rays fall upon the paper, the tangents can no longer be held to be proportional to the arc, and the value of a scale-division decreases from the center of the field toward the edge. These angles have their vertex at the position for the eye ; or rather, in this case, where the eyepiece is drawn out, in more general terms in the point through which all rays pass after emergence from the eyepiece, and therefore the distance of this point from the board is concerned. Instead of com- puting this from the dimensions of the system of- lenses, we in practice get a knowledge of this most simply by pointing the telescope toward the brightly illuminated sky and rendering the emergent pencil visible (as by blowing smoke upon it). Let us denote this distance, expressed in scale-divisions, by D, the angle of the cone of the sun's disk formed at the intersection by G; g is similarly the angle at the same point between the spot and the sun's center, p is the apparent radius of the sun, S its magnitude read off from the table, 5 the distance of the spot from the sun's center. Then we have therefore .,5 5 stanG tanG=-p, tan=-, whence 1= 1 tanG P G P 's'G'ta.ng But the last is the difference in declination of the spot and the sun; therefore . * tanG g in = rt - i P S G tang' which is most conveniently adapted to calculation in the form O2 2 log A8=logs+log -+- log sec G log sec g . & 3 3 A small table of double entry, with the arguments $ and p, gives AS directly. For the apparatus here D = i igPo, and on the average G = 19 30'. The diameter of the solar image measures somewhat over ten inches on the paper. " The transits for right ascension are as a rule taken four times, twice before and twice after reading off the declina- tions, each time over one thread. When the number of spots is large, as has often been the case in recent years ; and several groups fall at the same hour-angle, each section has to be determined for itself. The usefulness of the chronograph should be particularly recognized in such cases as this where the objects follow each other in rapid succession often separated by only a fraction of a second. The clock is regulated to mean time so that the differences of right ascension are obtained without further reduction, since the departure of the rate from apparent solar time does not come into consideration, never exceeding ^ViP The accuracy obtained, as well as the sim- plicity of the reduction and the whole procedure will be the more readily perceived from the following example. The separate groups of each day are distinguished in order of right ascension by the capital letters, the separate spots of the groups in the same order by the small letters with the attached exponents; but the most conspicu- ous spot of each group is assigned the letter without an exponent; different nuclei in the same penumbra receive subscripts. This mode of designation is preferable to that of current numbers. Introduction EXAMPLE 1863. March 13. CHRONOGRAPH READINGS DECLINA- CHRONOGRAPH READINGS R. A.

"The probable error of an observation was deduced to be o!n from a number of determinations of the time of transit of the sun's radius, by means of the deviations from the average of each day. For a spot the error in general will be somewhat greater; and since on the one hand this has to be multiplied by a number larger than V 2, while on account of being the average of four determinations, it must on the other hand be divided by 2, we may estimate the accuracy of the determination as i f 5. The probable error in declination will be about the same, since here the limit of reading is from ^ to -^ of a scale-division." The formulae now involved are simply derived by applying the three fundamental formulae of spherical trigo- nometry to the triangle having as its vertices the spot, the sun's pole and the center of the disk. Let Aa and AS represent the differences in right ascension and declination of the spot and the center of the disk. Let p be the "zenith distance of the earth as seen from the spot," and n be the geocentric distance of the spot from the center of the disk. Then n=p sin p, where p is the sun's radius. P is the symbol for the position angle of the spot, reckoned from the east through the north, and N is the position angle of the sun's pole. B is the heliographic latitude of the spot, B that of the center of the disk; L and L are the heliographic longitudes of the spot and of the center of the disk from the node. Then we have . =sin*cosP; P AS" =sm psmP . P smB=cos(pn)s,mB +cosB sin(pn)sin(PN) ; cosBcos(LL )=cos(pn)cos,B sin B sin(p n) sin (PN); cosBsm(LL )=sin(pn)cos(PN) . For adaptation to logarithmic computation, let g sin =sin (pn) sin (PN) , gcoBt=cos(pn) . Then we get sin B = g sin (B + ) ; cos (L L ) cos .B = cos (B + ) ; sin (L-L ) cos B= sin (p- n) cos (P-N) .' 1 It seems that it would have been more expeditious to use addition and subtraction logarithms and employ the first and third of the funda- mental formulae, solving (LL ) by the tangent only when necessary. vi Introduction An example of the author's reduction sheet now follows: March 13, 1863. o 11 46 Clinton Mean Time (I) (3) (4) (6) (7) (8) (9) sin (p n) (10) sin p a 1.71 647* 2.71687* 7 3047* o .0108 213 45' o.o8s6 c 180 21' 2.7l8S7* 9. 73217* .80Q2 9.0172 214 14 0.0818 c 1 80 -1- I 77 8 o8ic di 8.8285 8 0006 7.828l O OOOO 4- o 21 6 47 d* 8 7O33 8 e 1 ....

Carrington's telescope had an aperture of 4.5 inches and a focal length of 52 inches. He observed transits of the projected image across bars in the focal plane inclined 45 to the direction of the diurnal motion. The Observations made at Kew 1 with the photoheliograph, which in effect form a continuation of the Redhill series, were begun on February 7, 1862, and were continued for ten years. They accordingly cover the last eight years of Dr. Peters' work. The interval not included by the English observations was from March 25, 1861, to February 6, 1862, although the Kew instrument was being employed in a preliminary way during this time, so that the gap might perhaps be fairly bridged without the records of Dr. Peters. The Kew photoheliograph had an aper- ture of 3 . 5 inches and a focal length of 50 inches. 1 Warren de la Rue, Balfour Stewart, and Benjamin Loewy, " Researches on Solar Physics : Heliographic Positions and Areas of Sun-Spots Observed with the Kew Photoheliograph During the Years 1862 and 1863. Philosophical Transactions, 159, i-no, 1868. xii Introduction Spoerer's observations, as published (1874) in his first extensive memoir, " Beobachtungen der Sonnenflecken zu Anclam," cover the period from January i, 1861, to September 7, 1867. He first used a "3^-foot" telescope and ring micrometer; later he employed a "seven-foot" telescope, with a network of ruled lines in the focal plane. It is thus evident that the instrument employed by Peters was superior to those of his contemporaries, and his method of reduction was not less rigorous. A comparison of his positions of spots with those obtained elsewhere on the same dates is therefore of interest. Inasmuch as Spoerer used quite different elements of the sun's axis, and a different period of rotation from those employed by the other observers here involved, a new reduction of his positions would be necessary before any comparison could be made. This comparison is therefore not feasible here. In the case of Carrington's measures the conversion table given above serves to make the positions of Peters conform in longitude with those of Carrington, except for the difference in the value of the longitude of the node. For the purpose of comparison, 108 spots observed on fourteen days in 1860 by both Carrington and Peters were collected, only such spots being employed as could be regarded as certainly identified. The results are as follows: MEAN OF DIFFERENCES, PETERS-CARRINGTON In longitude, with respect to sign +39-' 2 In longitude, without respect to sign 45 . 2 In latitude, with respect to sign +13.4 In latitude, without respect to sign 28.8 Inasmuch as Carrington actually used a value for N smaller by 47' than he subsequently derived from his whole series of observations, his values in longitude should be increased by that amount. Hence the outstanding mean difference in longitude, P.-C., reduced to the same longitude of node, becomes 8'. Carrington's use of 1 = 7 10' instead of 1 = 7 15' introduces a slight difference in the individual latitudes, but this is practically balanced in the series of observations compared. We therefore conclude that there is no systematic difference between the positions of Carrington and Peters amounting to more than o?2 a satisfactory agreement. Accidental differences averaging from o?5 to o?75 occur, however. These differences are doubtless due, in large measure, to the fact that two observers can hardly agree in setting upon the nucleus of so indefinite an object as a sun-spot. The actual changes in the spots between the time of their observation in England and in America are also involved. The observations at Kew and Clinton are strictly comparable, after the latter are corrected in longitude for direction and rotation-period by our conversion table. For the purpose, 114 spots measured at both stations on 21 days between February 7, 1862, and July 2, 1863, were used, with these results: MEAN OF DIFFERENCES, PETERS-KEW In longitude, with respect to sign + 7 .'6 In longitude, without respect to sign 19.0 In latitude, with respect to sign 7.0 In latitude, without respect to sign 17.4 We may thus infer that differences of a systematic nature amount to scarcely more that o? i in either co-ordinate, while the accidental differences average o?3. The better accordance than that in case of Carrington is presumably due to the superiority of the Kew positions. Very considerable differences, however, are seen in the Kew measure- ments of the same spot when two photographs were made on the same day. We find that on ten of the twenty- one days used in the comparison of Peters and Kew such duplicate observations were made at Kew, the average interval between the two plates being 0^064. A comparison for 61 spots gave the following results, expressed in the sense first measure minus second measure : In longitude, with respect to sign 11.3 In longitude, without respect to sign 17 - 2 In latitude, with respect to sign 0.3 In latitude, without respect to sign 9.2 The accidental differences in the longitudes of the two Kew plates are therefore practically of the same magnitude as those of Peters-Kew; while those in latitude are only one-half smaller. This clearly tends to confirm the high opinion as to the accuracy of the positions of Dr. Peters which a careful examination is certain to give to anyone. Introduction xiii The regret is increased that his observations could not have been published shortly after they were concluded and during his lifetime. It is evident that they are of such a degree of accuracy that they might safely be made the basis of investigations of various problems of the sun's rotation, aside from their value as records of the solar activity. The editor acknowledges his indebtedness to his wife for assistance in reading the proofs, and to Mr. Philip Fox for aid in various ways; also to Professor Samuel J. Saunders, of Hamilton College, for his thorough but unavailing searches for the missing papers of Dr. Peters. YERKES OBSERVATORY THE UNIVERSITY OF CHICAGO September, 1907 HELIOGRAPHIC POSITIONS OF SUN-SPOTS In the following table of observed positions of sun-spots, the time given is Clinton mean time (astronomical) for the civil date. The first column gives the current designation of the spot by a letter, as used on the author's draw- ings and chronograph records. Capital letters are used for groups, small letters for spots, letters with subscripts for different nuclei within the same penumbra, letters with exponents for different spots in the same group; a letter with- out exponent or subscript is assigned to the most conspicuous spot of the group. Aa is the observed difference in time between the transit of the spot and the mean of the transits of the limbs, or is the difference of right ascension of spot and center of disk. AS is the corresponding difference in declination. In cases of large nuclei, the edges were often observed, designated by and 5 for declination; the means of the Aa and AS were then used in the computations. The size of the nuclei may be derived from these data. Measures were also frequently made on the margins of the penumbrae, but heliographic positions were not computed, and those measures, as well as the very infrequent meas- ures of faculae, have been here omitted. The heliographic latitude is given in the next column under the heading b. In the column headed L is found the longitude from the node; under L', the heliographic longitude. The letter in the last column serves to identify the spot on the next following date. In cases where the identification was regarded as doubtful by author or editor, the letter has been omitted. The gap in the observations from August 17, 1863, to November 2, 1864, is not due to a deficiency in the records, but to a prolonged absence of Dr. Peters in Europe.

SUMMARY BY DATES OF NUMBER OF SPOTS OBSERVED This summary was extracted from the fourteen observ- ing books of Dr. Peters, each of which contained such a list of the numbers of spots observed. A resume" up to August 17, 1863, was published in his article in Astro- nomische Nachrichten, 64, 213-218, 1865, with the fol- lowing words of description (translated): "The following table contains for each observing day the number of spots of which the co-ordinates were deter- mined as stated. To these are also added the days on which variable weather permitted the spots to be sketched only and not to be measured. For these, the numbers signify merely countings from the sketches, and they are therefore enclosed in parentheses. The observations were interrupted in August, 1863, by a long trip to Europe, and were not begun again until the beginning of Novem- ber of last year. The re'sume' may, therefore, embrace for now only the first series. Inasmuch as some time will be required for the complete publication I shall be ready, upon request, to communicate the details for separate days by letter."
