                           Observation Notes

Solar drift scans were made on 19 July 2002 around noon using the
LX-200 with the Baader solar filter and also including B, V and R
filters.  The roof temperature was 21 degrees.  The sky was clear
throughout.

The data were taken using the QuickCam CCD and StudioZero program.  The 
following parameters were the same for all scans (same as the data set
taken 15.7.02 except for exposure, as noted below).

frame size:     160 x 120
frame rate:     1 per second
decompression:  OFF
contrast:       255
saturation:     255
brightness:     127
white balance:  127


For the drift scans, "none" for filter means that only the Baader AstroSolar 
filter was used.  B, V and R refer to the Schuler filters (from the UBVRI set).
