Hi all,

. On 22 Jun 2016 20h51-52m UT, I photographed the pass of 2016-040-A and B
in HYA, LIB, VIR, before culmination, using a Canon EOS 6D + 28mm wide
angle (field 70°x47°). Both satellites were in time according to the Calsky
ephemeris and formed a nice triplet including 2007-001-B (Cartosat 2).
As expected 2016-040-B was 12 seconds ahead of 040-A.
Both satellites were also observed in VIR as mag 6.5 objects using
binoculars 50x10.
They were in their ninth revolution ; according to Calsky: "Earth
revolutions since launch: 8.6."

. On 23 Jun 2016 20h33-35m UT, I watched the pass of the 2016-040 objects
near Mu SER, using a Canon EOS 6D + 200mm teleobjective (field 11° x 7°) .
f/2.8 ; 3.2 seconds 2500 ISO.
According to Calsky ephemeris, I detected objects in the following order :
40C, 40F, 40E, 40B, 1975-004-AN , 40A. I missed 40H and 40G, being probably
too faint.

40A and 40 B were brighter objects, of mag 5, together with debris
1975-004-AN mag 6. All 3 of them were easily spotted with binoculars 50x10.
40C, 40E and 40F were much fainter objects, possibly of mag 7.5 or 8. They
escaped detection with binoculars in the twilight.
