    Greg Roberts observed OTV 2-1 on 2011 Mar 15 at 18:27 UTC. Paul Maley reported a video observation off-list, made on Mar
    16 near 11:48 UTC. Technical problems prevented him from reporting the precise time, but the track information was
    helpful in constraining the elements, updated as follows:
    
    X-37B OTV 2-1                                            321 X 341 km

    2 37375  42.7895 231.2052 0015332   4.1411 355.9582 15.80460231    09
    Arc 20110314.76-0315.77 WRMS resid 0.096 totl 0.042 xtrk
    
    The analysis has been complicated by an apparent gradual rise in altitude. I would not be surprised to learn that the
    OTV is several tens of seconds late tonight, relative the above elements. OTV 1-1 made frequent small orbit altitude
    adjustments during most of its mission.
