Object:		screen
Coll./type:	SR
CCD:		ABCD,1x1,low
Airmass:	--
DIMM:		--
Start:		0:20UT
Comments:       screen images for the newly installed masks

M400F117+953738_SR.fits
M289IC5063+952401_SR.fits
M325VIRMOS1+910527_SR.fits
M286FIMG215+945145_SR.fits

The exposures are taken with the He+1 and Ne+1 arc lamps - why?
An illumination gradient from bottom (brighter) to top (darker) is
	visible on all images

***********************
Commissioning programme
***********************
The acquisition in "fast" mode based on the slit images taken during
the afternoon failed.  Reason: The slit images don't contain the
information about the reference slits.
