Hello all;

The Soyuz TMA-19M spacecraft is expected to take off tomorrow 2015/12/15 at
11:03:09 UTC from Tyura-Tam Gagarin's pad. It will fly with the Soyuz-FG
classical rocket and they will try the fast 4-orbits renzezvous. Docking is
aimed to be at 17:24:09 UTC +- 3 minutes.

This TLE is the initial orbit estimation, just after spacecraft release
after SC separation from rocket:


SOYUZ-TMA 19M #0                                         198 X 214 km
1 70000U 15500A   15349.46667824 0.00000000  00000-0  00000+0 0    05
2 70000  51.6440 259.2934 0011851  54.4267  28.0135 16.25069103    09

Epoch is set at spacecraft separation & orbit enter time.

Soyuz-FG's third stage should re-enter in the next few days.

This time is not possible to estimate the renzezvous process as TsUP did
not provide the information of the process, so the spacecraft should be
late on time respect this estimation after the first automatically
programmed maneuver. Note that even closer to the docking the spacecraft
will go closer to ISS's orbit. Those are latest elements taken from
Celestrak:

ISS (ZARYA)
1 25544U 98067A   15347.85924076  .00017290  00000-0  26169-3 0  9997
2 25544  51.6440 267.4006 0008014 272.0100 195.3989 15.54742443975994

There are good passes over Europe about 1-2 hours before docking. Also,
there are good visual passes over Asia in the first two revolutions,
specially over Baikonur.
If clouded, Marco Langbroek informed on Twitter about the frequencies of
the Soyuz, that they are activated on Netherlands because the spacecraft
enters in range of russian tracking stations:
