December 3, 2019 – ALPO Comet News for December 2019

C/2017 T2 (PANSTARRS) is well placed in the evening sky for northern observers and should become brighter than 10th magnitude this month. CCD imagers are encouraged to image a number of fainter comets this month. In particular, the following are of interest. Interstellar visitor 2I/Borisov will be at its best around 15th magnitude. December and January will see short-period comet 289P/Blanpain pass within 0.09 au of the Earth. How bright this comet gets is uncertain as it is a faint, outburst prone object. Speaking of outburst prone comets, the British Astronomical Society invites CCD photometrists to join their effort to monitor the outbursts of 29P/Schwassmann-Wachmann.
