Hi All;

I normally estimate orbits for ISS launches and others, but normally I keep
to myself this data cause sometimes is wrong.

Here my estimation for tomorrow's Antares-Cygnus ORB-3 launch, assuming a
launch at 22:44:00 UTC from 27/10/2014:

CYGNUS ORB-3 estimation                                  198 X 255 km
1 70000U 14500A   14300.95278935 0.00000000  00000-0  00000+0 0    05
2 70000  51.6452 160.2168 0043469 137.1128   4.9765 16.17430254    09

For people who is not familiar with TLE format, this data can be easily
readed using Orbitron or any of those softwares:

For more softwares of any OS see:
http://www.celestrak.com/software/satellite/sat-trak.asp

We can see that the visual patterns for this launch are good because now
the ISS is on "marathon". It will be easily spotted on North America and
around -30 to -50 latitudes at evening. The magnitude for an overhead pass
of the Cygnus should be brighter than +2.

Any questions please off-list.


Jon.
