On 19 November 2016 at dawn I first watched the ISS passing at 5h33m UT,
then the awaited Soyuz arrived as expected about 18 minutes later.

I photographed it using a 200mm teleobjective on a Canon EOS 6D.


The Soyuz passed just above Sirius at 5h51m11s UT, what means it was only
9-10 seconds late in reference to Calsky ephemeris (TLE Epoch :
16323.29332069)  that stated :
. passing 0.25° above Sirius : 5h51m01.5s UT
. culmination: 5h51m12sUT ; H= 320 km ; mag 4.3 ; h: 12°7 SW ; hSun: 12° ;
v= 0.42°/s.

Here is shown an addition of six 1-second exposures taken from my garden in
Paris suburbs as the satellite passed by Sirius.

Notice the strangely dotted track of the Soyuz, as if a superimposed high
frequency flashing light were emitted by the spacecraft.
