The sky was very clear, albeit a bit light due to eternal twilight at my
latitude in summertime.

USA 161 was seen near the end of a 30 minute plane scan using the 35mm widefield
lens. I was just about to quit the session when it appeared, as a bright and
fast moving object. It evidently was near perigee when I observed it. It slowly
flared to mag -2 peaking near 01:30:27 UTC,  because of the fast movement a very
nice sight (and a very nice picture as a result).

With Leo's first post winter-blackout obs from a week ago (May 24) this obs
should constrain the current orbit much better.
