NOTES FOR OBSERVING
-----------------------------------------------------------------------
                                                                                
The goal is to get a simple time series photometry of an eclipse by 
U Sco (a recurrent nova at I~18 at minimum) so as to get an exact time 
of minimum.  [Many such eclipse timings are being accumulated with a 
goal of looking for the period change caused by U Sco's 1999 eruption.]
The times *must* be from UT 04:18 to 08:18 for U Sco (whose eclipse is 
centered at UT 06:18 {JD 2453893.762}) on UT 7 June 2006 {civil 6/7 June 
2006}.  Take 300 second integrations in the I-band, and keep repeating
for the entire four hour period.

Take the observations through any conditions, as I'll be doing 
differential photometry with respect to nearby stars.  Even a sporatic 
light curve through holes in clouds can return an eclipse time of some 
use.

The finder chart for U Sco can be found from the Downes & Shara catalog at 
http://icarus.stsci.edu/~downes/cvcat/Forms/varcat_query.html
Enter the name of the target (U Sco) in the box at upper left labelled 
"GCVS Name", click the "Submit" box on the upper right, then click on the 
name on the left.

At the start of the four hour period, move to U Sco, take a focus (if 
needed), check the center (so U Sco does not fall on a bad column or join 
line), then start the sequence with the 'MORE' command.  And stop when the 
four hours is up.  This program should be very easy.

NOTES FOR CALIBRATION FIELDS
-----------------------------------------------------------------------

No calibration, the photometry will be all differential with respect to 
nearby stars.
