    Tony, following your previous night's obs I propagated Mike's last elset
    forward to April 6 using his INT2 programme, then knocked .0025 off mean
    motion and ran predictions for last night (18/19 UT).  I found it very
    close to the predicted position and at the usual brightness.  Its ground
    track is now drifting westwards and I guess it will move down again
    sometime to stabilise the track at some new longitude.  Please continue
    to observe it as often as possible.
    
    Although there was some cloud around I failed to find the older Trumpet
    94 026A which was due shortly after.  I hope that one has not manoeuvred
    too.
    
    They have both been operating with equator crossings near 20/200 degrees
    so I thought this might be their preferred operating tracks.  This
    seemed a good starting point to look for the missing Trumpet 95 034A
    following Ted's message of a few months ago but, so far, no success.
