Corrected identification of object about to hit the moon
Short version: back in March 2015, I (mis)identified this object as 2015-007B, the second stage of the DSCOVR spacecraft.
We now have good evidence that it is actually 2014-065B, the booster for the Chang'e 5-T1 lunar mission. (It will, however, still hit the moon within a few kilometers of the predicted spot on 2022 March 4 at 12:25 UTC, within a few seconds of the predicted time. In fact, we've gotten more observations refining the impact point slightly.)
