    This is an unusual possible sighting. Back on Tuesday 4/18 at 22:54 PDT
    I thought I saw a brief flash to mag 1-2 as far left of Vega as Vega was
    high. The flash was very brief & I'm not sure about the magnitude.
    
    I forgot to check this for some days, but just ran a check against
    mccants.tle with a mag 15 limit and a very high perigee / range. To my
    surprise 23609 USA 112 is a good match, az 34 deg el 14 deg. If anyone's
    interested I can send the Skymap .cfg file that I used.
    
    Leo Barhorst's recent posting marks USA 112 as (Trumpet 2?). Wonder what
    it is. The orbit seems very eccentric.
    
    Its standard mag is 4.5 but its predicted mag was 12.5, so it must have
    been far away ...
    
    I'm surprised that a sat could flash 11 mag brighter than predicted, but
    I guess some high-orbit (near GEO) sats can flash real bright.
    
    Best wishes Mark
