Hi all,

Last night on 7 DEC 2015, I photographed the 2015-071 objects, passing according to Calsky ephemerides.
At first glance, before any detailed analysis, I imaged using a wide angle of 28mm on a Canon EOS 6D :

. Cosmos 2512 ; 17h02m-03m TU
. Cosmos 2511 as a couple of objects , a faint flashing one preceding a much brighter one (steady)  photographed from 17h10.9m to 14.8m TU
.  superbly flashing Volga Rocket  071-C around 17h35m TU.

I also observed all these objects using binoculars 50 x 10.

Both objects, from Cosmos 2511 pass, were separated by about 12 seconds. 
Alain Grycan photographed both objects too , passing by Gamma And at 17h11m 02s and 14s TU (as observed from Toulouse ; south of France).

The fainter object  (= the flashing leading one)  might be a debris from the bigger one ; it already orbited at a slightly lower altitude above horizon than the main object.
