YALO Nightly Observing Report for 1999 Aug 15

Observer: Juan Espinoza
Observed last half of the night from 0400 to 0930 UTC.
Conditions were Non-Photometric most of the night.
Problems were encountered, see the summary for details.

Seeing and Weather:
   Beg: Seeing >3 arcsec, Cirrus, Winds High
   Mid: Seeing 2.6 arcsec, Cirrus, Winds High
   End: Seeing 2.0 arcsec, Clear, Winds Moderate

Observing Summary:


Main reason for late star was strong winds and really bad seeing 
wich made for bad images just not worth doing. - At around the middle
of the night these conditions calmed down enough to observe.

As you may imagine - I accommodated the program in the best way possible.

Aql's differential magnitude in R band: ~2.1

VERY IMPORTANT - IR flats (mostly dark ones) have a strange pattern
that I can not described too well.
(I will do my best in the trouble report).
(see trouble report)

47Tuc was observed in U-band because the seeing was bordeline 2.0
