Observing Summary:


Hello,

Photometric program mostly completed.  PG1323 and 110-L1 not observed because of limits.
Very bad images for the first part and middle of the night due to terrible seeing condition.
My guess is that the first five hours are nothing but garbage.

Differential magnitudes:

4u1543:		1.3
Aql X-1:	3.48

Several problems were found during my first night.  More details on the Trouble Logs.

That is all
cheers
