Below are my obs of 85- 79 B in the last months:
85- 79 B 99-04-19 21:36:55 LB 119.3 0.5 10 11.93 AA, mag 5->7
85- 79 B 99-04-26 21:10:20 LB 120.4 0.5 10 12.04 AA, mag 4->inv
85- 79 B 99-04-27 20:38:05 LB 127.0 0.5 10 12.70 AA, mag 4->inv
85- 79 B 99-04-29 21:14:08 LB 126.0 0.2 10 12.60 AA, mag 4->inv
85- 79 B 99-05-02 21:18:51 LB 123.1 0.5 10 12.31 AA, mag 4->inv
85- 79 B 99-05-03 20:42:11 LB 49.7 0.5 4 12.43 AA, mag 5->inv
85- 79 B 99-07-06 22:15:38 LB 108.1 0.5 8 13.5 AA, mag 4->inv
It was even tumbling faster then Mike suspected.
Check the PPAS-files for more obs by other observers.
The estimated period of just over 14 seconds fits well with the above list.
It is an easy to observe object.
