Observing Summary:

Hello,

Programme partially accomplished. 

Charles, I could not observe ANY of the Y20003 objects! we had strong winds (up to 32 mph) coming from the north. Instead I decided to go to the next targets. Also, the last targets of the list was observed more than 5 times as wind again played its part.

Darren, Tdisplay did not work tonight. Please tell Juan to trim the your images which are in tonight's directory. See trouble report. 

Differential magnitude of,
Cen X=4    0.425
4u1543     1.31

See you next week,

David
