REPORT FROM LPARL
23-Dec-92, L. Acton

We end 1992 with the satisfaction of a very successful year of observing
with SXT and Yohkoh.  The first publications are now out and hard work is
in progress in many places on the next round of papers. 

The SXT itself continues to perform without problems.  Since losing the
entrance filter in November we have been unable to acquire images from the
aspect sensor.  Mees Observatory quickly installed a full disk white light
system on their spar to partially compensate for loss of this SXT data so
that it will still be possible to accurately co-align the Yohkoh images
with ground based data.  Now that we have developed techniques for
correcting for stray light in the x-ray images the prime function of the
SXT is practically unaffected by the change in the entrance filters.

Solar activity has dropped to the lowest level yet in the mission so we are
taking advantage of this to do long exposures and quiet sun investigations.

Please accept, on behalf of the entire SXT team, our warmest holiday
greetings.  Thank all of you for your interest in the Yohkoh mission and to
many of you for hard work and solid support of our research.  Please note
that Lockheed closes down from tomorrow (24-Dec) until Monday 4-Jan.  I
will close with a nice Christmas image borrowed from Roberto Falciani:
