Lacrosses and a very fine USA 161 flare

Coming back from a date shortly after midnight of August 23-24, I noted it was very clear, with only occasional small cloud fields passing. This allowed me to photographically target the optical imaging Keyhole satellite USA 161 (01-044A) and the radar Lacrosses 4 & 5 (00-047A & 05-016A).

USA 161 briefly brightened in Cassiopia, featuring a very short mag. 0 flare at 23:44:09 UTC. I was so lucky to have the camera open at that time, resulting in this very fine flare picture (with below it, the brightness profile):
