LEON CAMPBELL, Recording Secretary. COMET AND ASTEROID NOTES. Wolf's Comet. Careful search near the predicted place of this comet was made on the night of February 13, with the 16-inch telescope of Goodsell Observatory, but although the air was very clear no trace of the comet was found. It is therefore probably not visible with a 16-inch telescope. New elements, computed by Dr. A. Kahrstedt from observations at Heidelberg 1924 Dec. 22, 25 and 1925 Jan. 13 are given in the Copenhagen Circular No. 58. New Elements of Baade's Asteroid 1924 T D.- In the Lick Observatory Bulletin No. 359, Dr. H. Thiele gives the following elements of Baade's Asteroid 1924 TD, corrected by means of Lick Observatory observations between October 27 and December 2. These elements represent an observation on January 4 within +0556 in a and +3'"9 in 8. The computed magnitude on March 1 is 13.3. An ephemeris is given extending from February 1 to March 1. Professor J. A. Parkhurst, for many years a member of the staff of astronomers at the Yerkes Observatory, died on Sunday night, March 1, at the age of 63. His passing will be mourned by astronomers in all parts of the world. He was well known for his work in the photometric measurement of the light of the stars. Professor Solon I. Bailey, for nearly forty years a member of the staff of the Harvard College Observatory, retired on February 1, 1925, from the active professorship of Astronomy at the Observatory to that of Professor Emeritus. On February 3 his many astronomical friends, nearly half a hundred strong, tendered him a complimentary dinner, presided over by Mr. George R. Agassiz, chairman of the Observatory Visiting Committee. Professor Bailey, besides being responsible for the establishment of the Boyden Station at Arequipa, Peru, is particularly noted for his discovery and discussion of many hundreds of cluster variables. He has travelled extensively, investigating different localities for observatory sites, and for a number of years was responsible for the establishment and maintenance of a series of meteorological stations on the west coast of Peru, from sea level to an altitude of 19,200 feet, on El Misti. Professor Bailey expects to maintain an active interest in astronomy in spite of his retirement and his three score years and ten. Hood College Observatory. - Hood College, an institution of learning for women at Frederick, Md., presided over by Dr. Joseph H. Apple, began its second semester with the establishment of its newly erected observatory, which contains, among other equipment, an excellent eight-inch Clark equatorial. The new observatory building, besides having a well apportioned and commodious dome, has splendid facilities for classroom work and special investigations, with plenty of opportunity for further expansion. La Plata Catalogue C. - Publications of the Observatorio Astronomico de La Plata, tome VIII, contains a catalogue of 4412 stars between 62° and 66° of south declination, the positions of which have been determined principally by Hugo A. Martinez during the years 1919-1921. This is the third catalogue to be issued by the La Plata Observatory as parts of the general plan begun in 1919 to observe the zone from -52° to -82° of declination. The catalogue for the zone-66° to 72° is in preparation and the observations for the zone -72° to -82° are being carried on. Summary of Sun Spot Observations at Mt. Holyoke College, 1924 U. S. Naval Observatory Eclipse Observations, 1905, 1918, 1923.-Publications of the U. S. Naval Observatory, Second Series, Volume X, Part II, Appendix, gives a tardy account of the expeditions from the Naval Observatory to observe the total solar eclipses of August 30, 1905, and June 8, 1918. The volume gives full details of the expeditions and the results obtained and is illustrated with excellent reproductions of a number of photographs of the solar corona and of the flash spectrum obtained in Spain in 1905, and a single photograph of the corona of 1918 taken at Baker, Oregon, with a drawing of the inner corona, made by H. R. Morgan, showing details obtained from several photographs. The reproductions of the photographs of the chromospheric spectrum, obtained by S. A. Mitchell at the eclipse of August 30, 1905, are especially notable. At the end of the volume is given a brief report of the attempts to observe the eclipse of Sept. 10, 1923, from U. S. Navy airplanes. One observer, Lieutenant L. D. Webb, appears to have seen the solar corona from an altitude of 16,500 feet, above Point Dunne, California. He encountered fog and cloud at lower levels. Two other observers saw the corona through thin clouds. Total Solar Eclipse, 24 January 1925, from the Navy Airship "Los Angeles". - The following, from an abstract of a paper presented to the American Astronomical Society, at the Washington meeting in December, 1924, by F. B. Littell, was received too late to be used in our January issue. The complete abstract will appear in order in the report of the meeting. Eclipse observations from airplanes were proposed to the Naval Observatory by Prof. D. P. Todd in 1919, and again by Col. John Millis, U. S. A., retired, in 1923. Some attempts were made in 1923, but no valuable results were secured. The proposal to observe the eclipse of 1925 from a Navy dirigible was made to the Naval Observatory by Col. Millis. The advantage of the dirigible over the airplane for the purpose is the steadier and larger platform for apparatus and observers. The disadvantage is the inability to ascend so high if necessary to over-ride clouds. The North American Almanac for 1925 has recently come to this office. This book, styled "the Aristocrat of Almanacs," has made its appearance for five years in succession, each time a bit more extended than before. The issue for 1925 contains the usual information found in almanacs, namely, the times of sunrise and sunset, and of moonrise and moonset for each day throughout the year for Chicago. Tables are furnished for finding this information for more than fifty other cities in the United States. Besides this a large number of astronomical and other facts are presented in a simple yet accurate manner. Charts of the sky showing the stars that are visible are given with the dates when they are to be used. There are papers on various topics by writers who are recognized authorities in their fields. It is fully illustrated with one hundred and thirty halftones. One notes with satisfaction the lack of any attempt to forecast the weather for the year, which cannot be done scientifically for so long a period. The almanac is published by The North American Almanac Co., 124 W. Illinois Street, Chicago. O. L. Dustheimer, professor of Mathematics and Astronomy, BaldwinWallace College, Berea, Ohio, gave five lectures on the Solar Eclipse of January 24, 1925, in Berea and Cleveland. On January 21 his talk was broadcast by the Cleveland Radio Station WTAM. SHORT ECLIPSE NOTES. AT THE YERKES OBSERVATORY. The sky was totally cloudy here so that there was no opportunity for us to use any instrument. We were prepared to obtain the spectrum of the tips of the cusps with the Bruce spectrograph on the 40-inch telescope, using one prism centered at 4500. We expected to use four different kinds of plates: Eastman 40, Panchromatic, Lantern Slide, and Process. This was to be operated by Mr. Struve, making visual observations and exposures, while Mr. Sullivan set the slit at the proper points on the cusps, according to the pre-arranged program, while Mrs. Lee kept time, took notes and read off the program for the successive exposures. At the 12-inch telescope, the Yerkes spectrograph, with three prisms, had been so altered that it could be centered at 7200. Fresh kryptocyanin plates had been secured. This was to be operated by Mr. Barrett, assisted by Mr. Bobrovnikoff. At the 24-inch reflector, Mr. Van Biesbroeck was to use a focal plane shutter for direct photographs of the partial phases. Kryptocyanin plates were to be used on the bare chance that a trace of the corona might be caught. Carried on the mounting was the small concave grating which we used at other eclipses: this was to be operated by Miss Calvert, and we used films bathed in dicyanin, and for the region of 7600 a kryptocyanin plate was set tangent to the curve. This concave grating has a radius of 60 inches, hence a focus of 30 inches. At the Zeiss U.-V., Mr. Vanderlinden and Mr. Ridell were intending to take eight or more pictures in the violet, the 30° prism and 15° prism being used in combination. EDWIN B. FROST. AT CINCINNATI OBSERVATORY. At Cincinnati, the sky was clear except a thin streak of clouds near the planets, and the sun was already notched as it rose at 6:52. The maximum phase occurred at 7:57, when 0.91 of the diameter was covered; then Venus was visible to the naked eye and Jupiter could be seen with opera glasses; Mercury and the brighter stars were invisible. Dr. Elliott Smith obtained a number of photographs of the partially eclipsed sun with the 9-inch Cooke lens, and with a Century camera he obtained a set of images on the same plate at ten minute intervals. The last contact was observed by Prof. J. G. Porter at 9h 09h 41", using the 4-inch Clark telescope; with the 16-inch, I caught it at 9h 09h 40. The computed time was 9h 09m 39. EVERETT I. YOWELL. AT BALDWIN-WALLACE COLLEGE, BEREA, OHIO. Among the many groups that observed the eclipse of Saturday, Jan. 24, 1925, was the one at Baldwin-Wallace College, Berea, Ohio. This group consisted of about forty students, under the direction of Miss Pauline Chaffee, Student Assistant in Astronomy. First reports indicated that no stars were visible during the eclipse but this group would most emphatically contradict that statement. First contact was observed five seconds after the scheduled time, that is, at |
