    With clear skies and pass predictions made, i went and looked to see what i
    could obs of the latest launch, i was not disppointed.
    
    First up was the Minotaur R/B #26066 00004F, no accurate timing was made as
    i had to use my 10x50s to see it but it was close to the predicted time of
    02:28:21 28 Jan UTC. Az 105 deg El 62 deg. Mag varied from approx 5 to 5.5.
    Nothing was seen around it so i am pretty sure it was the R/B. I then
    diverted my scan as the others were to follow shortly according to my
    predictions. I soon picked up a bright, approx mag 3.5 object along the same
    track. As i followed it there was another object in front of it, much
    fainter at approx mag 5. It was leading the other object by approx 2.7 deg
    (my 10x50s have a FOV of 5.5). I tracked both objects but could not see
    anything else with them. I then looked to see if i could see the bright
    object at 1x and at that exact moment, there was a sharp mag 2 flash. The
    time was 02:29:24 UTC +/- 3 sec. Az 120 deg El 60 deg. Now which one made
    the flash i do not know. If the bright object was OCS #26063 00004C then the
    leading object was Opal #26062 00004B. At least that's my estimate of the ID's.
    
    These elsets were used for my predictions:
