NOTES FOR TARGET FIELDS
-----------------------------------------------------------------------

The dark of night is 11 hours long, and my half night is thus 5.5
hours.

IF NON-PHOTOMETRIC, then my 5.5 hours of observations will consist of
a time series starting in the last half of the night, say at 05:00 UT
running until dawn at 10:30 UT.  This will be easy, and since I am
using differential photometry, I can work through almost any observing
conditions (including poor seeing, some twilight, and thick & thin
cirrus clouds).
