    Hi all,
    I just observed Lacrosse 5 doing its disappearance trick. I think this explains 
    my non-observation of March 6th in combination with Peter Wakelin seeing it 
    easily only minutes before.
    Saw it making a nice pass here around 19:11-19:15 UTC (obtained two good trail 
    photographs, due to be measured), easily visible at mag. +1.5 or so. Just after 
    the last of my two exposures ended (19:14:52.1 UTC), and well before it should 
    get into eclipse, it suddenly disappeared from naked eye view, within maybe 3-5 
    seconds so very fast. This was at about 19:15:00-19:15:10 UTC or so.
    I think this might happened at March 6th as well, just before I started to look 
    for it.
