I would guess that the above drag term was generated by Ted Molczan's
"drag smoothing program". The actual Spacecom elset has a much smaller
drag. However, Ted's program generated that value because the mean
motion for this rocket has greatly changed over the last few weeks.
So this Zenit is a strong candidate as a newly accelerated object.
The most recent elset is:
1 22220U 92076B 96248.04426114 -.00000362 +00000-0 -16117-3 0 05553
2 22220 070.9990 186.8289 0014023 307.2877 052.6968 14.15389798196197
Even this small negative drag term seems real and could be an indication
of a continuing acceleration of the tumble period.
This object is currently visible from latitude 54 to 71 north and
54 to 71 south.
