    Another Space-Track bulletin was issued more recently.
    
    Geo IK 2 decay is now refined at 14:30 UTC +/- 2 hours.

    Sujet : GEO IK 2 observed during its final 24-hour in orbit
    
    
    On 14 July 2013, I spotted GEO IK 2 (2011-05A) passing by Epsilon Boo with an 1.9°/sec angular velocity in the twilight (Sun height : 8.0° below horizon) at 20h18m43s UTC, what was 6 seconds ahead the Calsky prediction. The brightness was quickly variable (mag 0 to 4 or 5). According to Calsky the height above Earth was 191km. There has been a small peak of solar activity in extreme UV on 13 July 2013 (at the moment it is slowly decreasing) . According to the latest Space-Track bulletin the decay might happen at: 14:44 UTC +/- 4 hours. The same night, I also spotted Persona Rocket 3 seconds ahead of Clasky prediction. 2013-28B is due to decay at the end of the month.
