Hi Mark,
Masat-1 is certainly not 2012-006A or 2012-006B. They are too far forward or behind this mornings observed path. Also 2012-006C is 14s ahead of my measurement. My vote goes to 2012-0006G for Masat-1 (although there is only 8s between D, E, F, G, H & J at the moment). Time will tell once the group spreads out a bit.
73s Simon, G7WIQ

I think they are here! They match closely with the pre-launch...
Now the lottery begins!

I was looking this morning as well, but couldn't find them. Analyzing the doppler shift indicated the pass was 50s later than the pre-launch TLE's indicated (for the 8:30 UTC pass over the UK) I updated the pre-launch TLE (by adding 50s to the Epoch time, and re-calculating the checksum) and the doppler correction on the following pass was much better. I guess the orbit may be slightly higher than predicted, resulting in a fractionally longer orbital period. 73s, Simon. G7WIQ

Anybody find the TLEs yet??
Using the pre-launch set this morning wasn't really great. It's amazing what 24 hours will do :)
For example, this moring I could hear Masat-1 and XATCOBEO "below the horizon" according to the pre-launch set. So it's appearing later than predicited using this set.

Good 32 deg Masat-1 pass over ZL at 0911UT. 373 frames decoded and good solid signals throughout the pass.
