Last night , on 10 July 2015, I planned to have a look at the newly launched 2015-032B according to Calsky ephemeris.

Using 50x10 binoculars , I detected in fact a succession of 3 more or less bright objects, passing at a few degrees from each other, just beyond naked eye visibility apart from a few bright flashes.

At the same time I managed to photograph these newly launched 2015-032 objects, successively in UMI, CRB and SER. I got more than 15 photos of 4-sec duration, ISO 5000 , Canon EOS 6D + 200mm at f/2.8,  in a span of 2 minutes at 22h54m-56m UTC. From the photographs it is clear there are 4 objects. The first one is brightly flashing. I may nevertheless have missed it visually because it is followed by a stunning group of 3 satellites, very close from each other and variable in brightness. The last one, being strongly variable, flared superbly in CrB.

At the moment I have no time to analyse in detail these very interesting data. I will do it later.
