    MUOS 2 is scheduled for launch from CCAFS on an Atlas V-551 on 2013 Jul 19; the launch window is from 12:48 to 13:32
    UTC. Launch coverage is available at Spaceflight Now:

    The following *rough* TLEs are based on launch at window-open.
    
    MECO 1                                                   167 X 624 km
    1 79701U          13200.54190972  .00000000  00000-0  00000-0 0    00
    2 79701  28.0000 310.4417 0337670 130.0000   3.3000 15.58830000    02
    
    MECO 2                                                 193 X 34447 km
    1 79702U          13200.55196875  .00000000  00000-0  00000-0 0    00
    2 79702  26.0000 312.8421 7227302 179.9293   1.5500  2.38040000    07
    
    MECO 3                                                3801 X 35786 km
    1 79703U          13200.65131597  .00000000  00000-0  00000-0 0    02
    2 79703  19.1000 318.0624 6110508 179.0000  88.4351  2.05080000    05
    
    The MECO 3 estimate is likely the most accurate of the three, and should be reasonably close.
    
    Spacecraft separation is planned to occur at T+2:53:33. Soon afterward, the Centaur will conduct a Collision and
    Contamination Avoidance Maneuver (CCAM), followed by a blow-down of remaining Centaur propellants. The typical Centaur
    end of mission occurs 4400 s after spacecraft separation. Prospective observers should use the MECO 3 TLE to evaluate
    visibility.
    
    Eventually, the payload will enter an approximately 5 deg inclined GEO orbit in one of the existing UFO slots.
