As discussed earlier this month, theta A Orionis (in the Trapezium) 
will undergo an eclipse this weekend (fFriday night/Saturday morning. 
The weather outlook is good. While there will be a bight Moon, it 
will not be a problem.

I have been getting baseline BVRI CCD data over the past few nights 
and plan to do an all-nighter Friday/Saturday. Gene Lucas is coming 
by to help. Anyone else interested is welcome. We could use help as 
this can get pretty tiring. Orion is above the observatory walls 
about 10:30 PM MST so we will start about then and continue as long 
as we can. We welcome anyone else who would like to come by or do 
their own photometry. Because the stars are so close together, CCD 
long focal length photometry will work best (no focal reducers).

For more information, please drop me a note.

Jeff
