3200 Phaethon - 3.12.2016 at 18.20 Helsinki, Maunula Observation number 58703

Visibility I / V

Jorma Ryske, Etelä-Suomen kosmol. seura

The Little Planet 3200 Phaethon is a fading comet from which the giant flock of starburst Geminids, visible in mid-December, is from. Phaethon has seen comet-like activity in recent years when it is close to the sun so it is probably the same type of small body in the solar system as the 174P / Echeclus. Phaethon is currently moving in Pegasus Square. The first image is stacked according to Phaethon where it appears as a weak spot and the second is a star-stacked image where Phaethon appears as a _very_ dim line as it moves during a 30 minute exposure for about 30 arc seconds. The brightness of Phaethon is estimated to be between mag 17 and 18.
The brightest star from Phaethon at 11 a.m. is HIP 114806 mag (V) 8,010. From Phaethon in the 9 o'clock direction is the galaxy PGC 70838 mag15.96, and in the lower right corner NGC7539 mag12.60.
