The braking of 1993 29 A (#22643) probably took place in the morning of Feb.10, 1995. It is decaying at a normal rate - on March 18 ? 1993 44 A (#22709) was also forced out of its orbit, probably on Feb.26. It appears to follow the strange pattern of #22585, which was station- keeping in the same orbital plane as #22643 and #22709, until about Sep.24. From that time, its MMdot2 value was very low, until Dec.10, when it suddenly took a jump, as if its orbital maneuvering system had been running continously until running out of fuel. Here are some excerpts from elsets for the three objects. Notice the similarity of MMdot2, exc. and MM for #22585 on day 94268 and #22709 on day 95067 ! NORAD Epoch MMdot2 exc.
