    WGS 5 is scheduled for launch from Cape Canaveral on a Delta 4 Medium+(5,4) in about 11 hours, on 2013 May 24, between
    00:27 and 00:57 UTC.

    I offer the following rough TLE of the orbit after the final burn of the 2nd stage, assuming launch at window-open: 
    
    SECO-2                                                 440 X 66991 km
    1 78901U          13144.04069444  .00000000  00000-0  00000-0 0    02
    2 78901  24.0048  67.6288 8299446 177.8402   1.4113  1.08160032    04
    
    Following spacecraft separation, observers within range should look for the following 2nd stage events (times
    approximate):
    
        T+       UTC
    00:45:00  01:12:00  CCAM Start (Collision and Contamination Avoidance Manoeuvre)
    00:47:20  01:14:20  CCAM End
    00:54:41  01:21:41  H2 Depletion End
    00:56:40  01:23:40  O2 Depletion End
    01:18:33  01:45:33  N2H4 depletion End
    
    The fuel dump could produce a spectacular comet-like phenomenon, similar to that of WGS 4, imaged last year despite
    challenging conditions by Willie Koorts:
