Tonight , 13 FEV 2017,  I photographed the 7 objects 2017-003 A, B, C, D ,
E ,F, G.
They were rather fainter than expected (between mag 5 and mag 6.5)

First pass (culminating East)  :

BCDEFG passed as expected according to the Calsky ephemerides that used TLE
epochs near 17044.5.
However I missed 003-A (Iridium 106) that did not pass at the predicted
time.
Note that the Calsky ephemeris used for that satellite an older epoch  than
for the other objects.

Second pass (culminating West) :

I began watching  the missed satellite A more than 5 min before the
predicted time.

I spotted 2017-003-A Iridium 106 passing 3mn49s ahead from Calsky ephemeris
whose TLE epoch was :  17042.07067006
