2006 UN216

This sequence of 3 track-and-stacks was taken on the evening of October 30, between 22:09 and 23:19 UT. This amor-class NEO was moving slowly at a speed of 0.8 arcsec/min through the constellation Eridanus. It was caught low on the eastern horizon just about 8 degrees altitude at a magnitude of 19.2. We decided to give it a shot when it was listed as 6U330EF on the NEOCP. It was a discovery by the Catalina Sky Survey made on the 28th.

Despite the unfavourable position in the sky we where able to make it clearly visible.

Unfortunately our astrometry was lost due to an formatting error in the email sent to the MPC so it was not accounted for. I realized my mistake a couple of days later, when I couldn't find an entry in the DOU.
