Observing Summary:


Hello -

Program completed from beginning to end with nothing but cirrus and more cirrus.
At the start of the nigth clouds were a bit thicker than most of the night,
but in all, covered skies.  But observable skies.

Some OSU targets were observed twice because of poor imaging.
Target ob2k015 was observed not knowing if non-photometric
weather was a bad factor. (good images 

XTE	:  19.09  *** Magnitude fluctuated throughout the observing run.
Aql	:   3.9  *?*?*
4u1543	:  16.66 

The very last secuence of XTE1550 was interrupted (very rudely, I might add)
by the hard limits swichtches that were intalled some time ago
At 1015-UT.

cheers
