    With regard to:
    
    http://www.satobs.org/seesat/Jan-2012/0092.html
    
    I compared the measured flash positions (in RA/Dec) on the CCD image against a 
    tle for 78-058B. Taking into account the delta T between predicted and measured 
    end of the trail, I adjusted times untill predictions matched these positions 
    (or otherwise said: untill each flash had a similar delta T as the trail end, 
    compared to predictions).
    
    Doing so, the main flashes are on average 2.98s apart, based on five measured 
    flash positions corresponding to:
    
    flash, UTC (Jan 9, 2012), brightness
    ------------------------------------
    flash 1, 03:04:06.49,  mag +15.5
    flash 2, 03:04:09.47,  mag +16.0
    flash 3, 03:04:12.38,  mag +16.0
    flash 4, 03:04:15.28,  mag +15.6
    flash 5, 03:04:18.40,  mag +15.3
    ------------------------------------
    
    Each of these main flashes has a secondary flash on either side, in this pattern:
    
    .*.  .*.  .*.  .*.  .*.
