 HV on during SAA passages.
TJD 8490 = 22 August 1991

Because of an error by FOT and/or CMS at GSFC, the high voltages
were not turned off during the first two(?) SAA passage on TJD 8490.
As a result, the gains were messed up.  The AGC apparently was able
to adjust the voltages back to what they should have been, partially
after the first exit from the SAA and then fully after the second exit.
There may have a third, more limited passage through the SAA but it
did not have a noticable effect on the gains.

This SAA passage was noted by someone on a plot of a current, probably
when the data were first examined, but the event was not documented in
a text file like this.
