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!
