Sighting of OTV 4 from Almería. The really bad photos, but enough thanks to
Astrometry to identify that the steps are in line with what was foreseen in
the last update (I updated this morning). Although my time is not usually
good, I'll say that it happened 22-23 seconds behind my watch, most
satellites usually do it with 16-19 seconds, so I guess it's more or less
okay. For the orbit I have checked the stars around the 5 paths of 5
photos, and they all seem to be in place.
Based on the given orbit, I may choose points for the brightness as with
other satellites. But maybe late, even someday, because both this evening
yesterday and this predawn today I have caught too many satellites and too
many satellite points. Therefore, I have stopped first to check, despite
the badness of the photos, both trajectory and passing time in order to
avoid any possible surprises.
Although the photos are really bad, I leave them as it has decoded
astrometry.
The exposure times are 12 seconds (I accidentally gave the time button,
instead of the 8 seconds), the time in the file names is the local time
(UTC + 1), so subtract one hour to find UTC.
