AXIS Observing Report
                        ~~~~~~~~~~~~~~~~~~~~~


Dates:		2001 June 12,13,14,15
Instrument:	ALFOSC on NOT
Observers:	Pete Wheatley, Silvia Mateos, Darren Baskill

Grisms:		4, 7
Slits:		0.75, 1.3, 1.8, 2.5 arcsecs
Filters:	B, V, R (for SS397)

Observing conditions:
		Generally good conditions. Mainly clear skies, though not 
		actually photometric except perhaps on first night. First 
		night we were severly constrained by high winds which forced 
		us to observe downwind for most of the night and probably 
		contributed to poor seeing through buffeting of telescope. 
		Dust on third and fourth nights. Worst on third, but not a 
		serious problem. 

Seeing: 12th	Started poor at 1.4" and suddenly deteriorated to >2"
		at around the time we made photometric measurements of SS397.
	13th	Poor at 1.4-1.5"
	14th	Started good at 0.9" and improved to 0.7"
	15th	Start very poor 1.8" imporved gradually to 1.2"

Time lost:	None

Also SS397 photometry (BVR with Landolt standard field 110 before and after). 


Chip binning/windowing:
		Used NOT recommend chip windowing for spectra. Used 2x binning in spatial 
		direction only during bad seeing. Used smallish window for object acquisition
		images. Used full chip for SS397 photometry. 

Rotator: 	Different rotator angles were choosen for many fields in order to place two 
		or more candidate objects on the slit simultaneously.

Calibration frames:
		For each field pointing took He (1s and 5s) and Ne (1s) arcs, and usually 
		3x 5-30s (depending on slit) Halgen flats. Also took some sky flats with no 
		filter, grism or slit; and some sky flats with slit and grisms (for slit 
		illumination). Biases taken each night for each binning/windowing 
		combination used.
