Nico Janssen, PA0DLO, noted that 18th Space Control Squadron (18SPCS) has swapped the satellite names associated with object 41845 (was CAS-2T) and another object 41847. Therefore CAS-2T is now object 41847. Nico's detailed doppler measurements confirm that CAS-2T is in fact object 41847. (Note: the payloads CAS-2T and KS-1Q still remain attached to the CZ 11 fourth stage.) Thanks Nico, good catch!
The PICSAT team and Albert Van Duersen indicate that a better set of TLEs for PICSAT is now object 43132. Nico Janssen has also noted that the best TLE set for PICSAT has been unstable since November 14th of last year. Nico says that now object 43132 and even object 43133 are better matches for PICSAT than object 43131. Therefore, we will use object 43132 for PICSAT for now. The problem is the closeness of objects 43131, 43132 and 43133. Nico says he will continue to monitor these objects as they slowly separate over time. More later.
