I tried to image 2010 CA261 using both T08 & T32 at Siding Spring, Australia on the morning of 2021 Aug 18. Nothing appears at the predicted position. Stars were recorded to fainter than 16.5 magnitude. The prediction is for 10.5 at that time.
Try running the motion into the future & watch it realign with the earth every year. If the H value of 16.6 is picked up as a default, then the mag estimates aren't reliable. The ST4v estimate of 1-3 km is certainly suspect.
Interesting is an understatement, Greg. As Spock would say, "Fascinating!"
