Observing Summary:


Well...

Program accomplished with some modifications.  For starters I had a crash
on the second secuence of hd209458 and in my hurrying around
I forgot to check the IR-tilts and because of that images 
ir991202.0014 to ir991202.0091 have a slight error on the starting
tilt position.

	Should be: t1=1349 t2=2316 t3=1891
	was      : t1=1379 t2=2316 t3=1861

Of course I corrected the problem as soon as I became aware of it.

As far as keeping the object star and it's comparison one within the 
optical field,  It was not offseted in an orderly fashion as I had done in past days
but in many other ways in order to keep the target inside the chip (both IR & CCD)
(better seeing than yesterday, though...)

Rene Mendez:  2mass2223 was not possible to observe because of out of reach.
instead I replaced it with den0255 -- I figured that it was the best thing to do.

I am sending to La Serena tapes for:

	PORTUGAL:	991103 - 991201
	YALO (yale):	991122 - 991201
	CTIO_MAZA:	991130 - 991202

All other programs observed with no complications. (thank god!)

Crash: same as always.

Cheers,
juan
