       Activity:

        1) Stellar observation of 38 Aquarii

	Sequence:  Take1UV 

        SCI_SPEC:  Radiometric Calibration

	OBS_PROG:  Calibration

	SCI_OBJ:   Radiometric Calibration

	OBJ:       38 Aquarii

        ONUMs = 3541 (39 exposures) 

        Instrument configuration:
 
                - Pointing:  Sun center
 
                - Roll: PA= SW with minute corrections
 
                - Mirror/Occulter:  6.9 to about 7.55 Rsun

        2)  VLC stray light test
 
        Sequence:  97.02.20_marco
 
        SCI_SPEC:   Measurement of pB at several heights.
                    At each height the int. occulter is moved
                    to vary the mirror width. Purpose of the test
                    is to measure the constant fraction of pB stray
                    light.
