ROTATION PERIOD DETERMINATION FOR 280 PHILIA – the lightcurve more readable these have been reduced to 1828 A TRIUMPH OF GLOBAL COLLABORATION points with binning in sets of 5 with time interval no greater than 10 minutes. Frederick Pilcher 4438 Organ Mesa Loop MPO Canopus software was used for lightcurve analysis and Las Cruces, NM 88011 USA expedited the sharing of data among the collaborators, who [email protected] independently obtained several slightly different rotation periods. A synodic period of 70.26 hours, amplitude 0.15 ± 0.02 Vladimir Benishek magnitudes, represents all of these fairly well, but we suggest a Belgrade Astronomical Observatory realistic error is ± 0.03 hours rather than the formal error of ± 0.01 Volgina 7, 11060 Belgrade 38, SERBIA hours.

This comet, a brilliant object which is often referred to as “Tycho Brahe’s Comet” and which is one of the most important scientific comets in history, is next week’s “Comet of the Week.” NOVEMBER 1, 1948: Observers on the ground near Nairobi, Kenya, as well as in a Royal Air Force plane flying at 4000 meters, detect a bright comet near the sun during a total solar eclipse. The Eclipse Comet of 1948 and other “eclipse comets” are the subject of a previous “Special Topics” presentation. NOVEMBER 1, 1975: University of California astronomer Martin Cohen publishes a paper announcing the likely presence of water ice surrounding the young solar-type star HL Tauri. A protoplanetary disk has since been detected surrounding this star. The significance of Cohen’s discovery is discussed in a previous “Special Topics” presentation. The protoplanetary disc surrounding the young star HL Tauri is seen in this sharp image from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. It reveal substructures within the disc that have never been seen before and even show the possible positions of planets forming in the dark patches within the system. Courtesy ALMA (ESO/NAOJ/NRAO). NOVEMBER 1, 1998: A team led by William Merline discovers a moon, since named Petit-Prince, around the main-belt asteroid (45) Eugenia with the Canada-France-Hawaii Telescope at Mauna Kea. -

THREE MAIN-BELT ASTEROIDS Stephen M. Brincat As evidenced by the figure below, rapid growth continues for the Flarestar Observatory (MPC 171) Minor Planet Bulletin. Volume 43 (2016) had a record number of San Gwann SGN 3160, MALTA 366 pages and results for more than 700 asteroids. [email protected] (Received: 2016 August 13) Photometric observations of three main-belt asteroids were made from 2016 March to June. The results of the lightcurve analysis are reported for 1154 Astronomia (1927 CB), 3680 Sasha (1987 MY), and (6138) 1991 JH1. The purpose of this research was to obtain the lightcurves of three main-belt asteroids: 1154 Astronomia (1927 CB), 3680 Sasha (1987 MY), and (6138) 1991 JH1 in order to determine the rotation period for each asteroid. A search of the asteroid lightcurve database (LCDB; Warner et al., 2009) and other sources did not find previously reported lightcurve results for these asteroids.
