ERBS came to shine up to magnitude +0.5 somewhat before photography
(magnitude +1), and relatively low towards NW. It was red and like an
artifiial fire (seconds later another satellite reached magnitude +0.5, but
more naturally, still pending processing). At first I had my doubts in a
night full of fireworks, but the long time and the later entrance in the
shade made it clearer to me.
Astrometry and HeavenSat ended up confirming it.
Photography data:
Date: 20181231
Time (UT): 18:47:46
Exposure: 8 seconds.

 am still a bit surprised at how it is possible that SAOCOM 1A, one of the
brightest satellites that can currently be seen in Heavens-Above or CalSky,
still does not appear. At least since the beginning of December it is easy
to see, and since just before Christmas followed almost daily, except for 3
days, it has always been confirmed, magnitude around 0 towards the zenith
(this morning again) and at least magnitude in around +2 towards 30º of
Elevation. Certain that something else has shone once

On the other hand, also in the afternoon of 2018/12/31 Tandem-X and
TerraSar-X shone more to the South than I imagined (I still have it
unprocessed, but if I remember it, then I will send data from the mirrors)

3602, 36.8389ºN, 2.4498ºW, 31m, Almería (Spain)
