Hello all,

Congratulations to Greg!

OTV-4 was a bit more than 6 degrees off-track on mid-elevated sky and one
minute and 15 seconds early on Greg's first pass (the higher one). It was
near to complete a full revoulution off time respect february's elset
derived from Jose Luis Ruiz's photographic observations, that was ~0.06
rev/day too high.

This is a derived rough orbit:

OTV-4 search                                             325 X 337 km
1 40651U 15025A   17084.75186662 0.00009973  00000-0  50000-4 0    00
2 40651  38.0095 214.3059 0008615  58.6322 301.5307 15.80614973    06
rms 0.06

The results of the analysis suggest that the object has another ecc and AoP
values, probably a higher ecc, beeing these values the closest that I've
could get with the available data. The residuals looks enough good to be
able to spot it reasonably easily in the next days.



Jon.
