Yesterday I reported:
>>
Imaged two UNIDs.
They were ID-ed using Sattools Satfit.
Norad    d ARG  d RAAN  d rms               TLE age
15071   -7.724    0.428     0.901 15724A    2.024
>>


The risiduals were high:
>>
Norad Cospar         X-track           delta T      TLE age  range
15071 84 065C   | -2.13571 deg -141.906 sec   2.0 day, 1604.2 km
>>

Cees Bassa mailed me that the residuals were too high to be a good match.
The astrometry is probably wrong.

So I reduced the images again.
Indeed the astrometry was a bit off.
I now get a perfect match with 24839 97 030D.

Please replace

A point in the next image was added.


The 2nd Unid turned out to be an aircraft.
Delete the entry for 99208.
