Matt,

This type of Cosmos-satellites might display flares. I found in my log
following cases:

13552 Cosmos 1408 (82092A) mag -2
15592 Cosmos 1633 (85020A) mag -1
16495 Cosmos 1726 (86006A) mag -0.3
17566 Cosmos 1825 (87024A) mag +2
18421 Cosmos 1892 (87088A) mag -2
18958 Cosmos 1933 (88020A) mag +1
19210 Cosmos 1953 (88050A) mag +1
22626 Cosmos 2242 (93024A) ?

Most of these objects have been observed unintentionally.
I suppose more flares should have been observed when one should check every
possible transit.

This type of Cosmos is probably no longer in use. The last launch
occurred in 1994 if I am well informed.

Bram Dorreman,
COSPAR 4160 (Achel 1):
51 16' 45.5" N (51.2793 N),
