Potential Earth-impactor (99942) Apophis on UT 2021 Jan. 16 (18:21 and 21:45). Exposure duration is 2520 and 2640 seconds. The FOV is 51x51 minutes of arc, orientation north-up/east-left. At the time of observation the object was 111.0 degrees from the sun and 0.204 AU from the Earth. The parallax effects of the spacecraft during nearly half an orbit (101 minute orbit) are seen in the star arcs. The radial profile of the object shows no sign of cometary activity.
