I watched for flares from Iridium 11, 12, 13 at 1-power Aug.26
(only over a 30-degree track) and saw nothing (19:33-19:49 UT)

Iridium 14 was detected 19:57 in 7*50 just above gam Per at mag +4.2,
brightened soon after to +3.0 for 5 seconds. Faded to +5.5 near M31.

Iridium 16 was found 20:06 at -1 (missed the brightening?) for 6 sec.
5 degrees above gam Per. Faded to about +3 for 50 sec, then to +5

Sadly, it is still too bright in the mornings to see the new bunch,
and definitely not in SW

My first 'duration' is very subjective.
