    You may have mistaken beta UMa for alpha - it is very obvious that you
    saw one of the Navy Ocean Surveillance System trios :

    They are in McCants.tle, normally mag +5.7 at 1000 km but now and then
    they can reach +1 or +2
    
    In the attached SkyMap (Rob Matson) graph I have connected the predicted
    positions at 21:37:40 to show the triangular arrangement.
    
    You can also see an Iridium entering Earth shadow, and two Meteor rockets
    leaving it, at around the same time and place.
