    Clear sky, cold, some cloud fields around 19h UTC. Observed and photographed a 
    -7 Iridium flare (URL to follow in later mail).
    
    05-016A (Lacrosse 5) did its disappearance trick twice at two different passes, 
    once I have it on photograph again, once it disappeared 5 seconds before the 
    camera opened. Times for these disappearances: 17:30:44 UTC and 19:13:15 UTC
