Visibility I / V

Jorma Ryske, Etelä-Suomen kosmol. seura

Comet 315P / 2013 V6 (LONEOS) is perhaps a bit dimmed compared to the picture I took a week ago. The coma is dense almost star-shaped and still shows a faint short tail of about 50 "in the direction of PA 210 °. At the bottom of the image are the galaxies NGC 3788 mag12.60 and NGC 3786 mag12.40.

According to the stars, in the stacked image, a faint streak of about 1 arc minute stands out from the comet to the left in the 10 o'clock direction. It is apparently an asteroid (34751) 2001 QO100, mag16.86.
