January 20 - Asteroid 2022 AB
Fast rotating near-Earth asteroid 2022 AB was first observed at GINOP-KHK, Piszkesteto (K88), by K. Sarneczky.
The asteroid passed 9.6 lunar distances from the Earth on January 20th, 2022, at 13:21 UT. Filipp Romanov observed 2022 AB remotely using the ARO as part of the observing campaign for 2022 AB. Unfiltered photos were taken over several nights in January 2022, with exposure times of 18 and 10 seconds for each image. For the first time (previously Filipp had only did phase plots of variable stars, including discovered by him),
I plotted the rotation phased light curve of an asteroid. I made photometric measurements (in MaxIm DL software) of the asteroid in comparison to V magnitudes (from the APASS DR9 catalog) of nearby stars from 590 images taken on 2022-01-11 (from 02:08:55 to 09:30:48 UT). Below is the phase plot created in VStar software for the best (which is searched using VStar) period = 0.002105 days = 181.87 seconds.
