Hi,
Yesterday, the 11th, at 06:51 (local time), 5:51 (UTC), I saw a white flare of
magnitude between -3 and -4, just 2 or 3 seconds long.
After looking at HeavenSat, there are two candidates: NOAA 18 and Fengyun 1C
DEB (30495), but after looking more closely, the resemblance is NOAA 18.
The following image, although with an exposure time of 16 seconds, only
shows part of the time in reference to the satellite, as a second is lost down
the magnitude of antiflare. In it, the brightest part is at a magnitude of
about 1.5 and when you lose about 2.5
Regarding the mirror, roughly it corresponds to (58.6º 50.9º) in magnitude
+2.5, and (56.9º 48.4º) in magnitude +1.5
The flare may between -3 and -4 should occur at (54.2º 45.4º) or sometime
between the mirror and the corresponding magnitude +1.5 point
