TEMPLATE FOR CI AQL ON 30 JULY 2006


-----------------------------------------------------------------------
NOTES FOR OBSERVING
-----------------------------------------------------------------------
                                                                                
The goal is to get a simple time series photometry of an eclipse by 
CI Aql (a recurrent nova at V~17 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 CI Aql's 2000 eruption.]
The times *must* be from UT 04:10-06:10 for CI Aql (whose eclipse is 
centered at UT 05:10 {JD 2453947.717}) on UT 31 July 2006 {civil 30/31 
July 2006}.  Take 60 second integrations in the V-band, and keep 
repeating for the entire two 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 (CI Aql) 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.

Please center the position a bit off-center (by ~10% of the FOV) so that 
the variable and it comparison stars are all in one quadrant.
At the start of the two hour period, move to CI Aql, take a focus (if 
needed), check the center (so CI Aql does not fall on a bad column or join 
line), then start the sequence with the 'MORE' command.  And stop when the 
two 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.

1. Take 11 flats for each filter and 11 biases
