                   CHIEF OBSERVER'S REPORT for Week 48
                        21-Nov-99 to 27-Nov-99


GENERAL 

Solar activity was high, with many (11) M-class flares and one X flare,
the third of the year.  Most of the biggies were from AR 8771 (CMP 22 Nov,
just crossing the limb today. However all eight of the ARs listed for
Nov. 27 were delta type!

SXT TECHNICAL 

There were no problems during the week.

For Web material see

Current Week: http://isass1.solar.isas.ac.jp/sxt_co/991126.html
Index:        http://isass1.solar.isas.ac.jp/sxt_co/index.html

This week's science nugget dealt with an old analysis of superhot
flares observed by Yohkoh.

CAMPAIGNS 

There were no organized campaigns this week.  We continued taking
higher-cadence quarter-resolution FFIs.  Dave McKenzie's AEC parameters
worked well, giving us adequately over-exposed images for a range of 
brightness.

                      SXT TABLE PLAN, WEEK 49 
                      (29-Nov-99 to 05-Dec-99)

There are no official campaigns planned.  Therefore, we continue
the high cadence QR sequence (FFI) and AEC-enabled overexposed 
PFI sequence.
