Observing Summary:

Hello,

Programme full accomplished without problems. Some long pauses requested by Charles to make his appearance in the new Yale production (starring Charles Bailyn as himself, co-starring David Gonzalez).

Beccah, good news about the asteroids (all of them!).  Charles will tell you about the tricks we found out to obtain good images. Basically 900s exposures results in good images, while 1200 or longer do not work.

Differential magnitude of,

Cen X-4  4.36
4u1543   1.31
XTE1550  5.19
Aql X-1  3.46


That's it or maybe I should right

The End

David
