                   CHIEF OBSERVER'S REPORT for Week 05 
                       24-Jan-00 through 28-Jan-00 


GENERAL 

Activity dropped, the background staying in the mid-'B' level most
of the week.  Several C flares were observed, but no M flares.


SXT TECHNICAL 

The CCD streak artifact reported last week continued to fade away.  It was
still visible at the end of the week, but diminished in intensity.  Some
Y2K bugs were found in the analysis software, and the appropriate people
are working on them now.

                       SXT TABLE PLAN, WEEK 6
                      (30-Jan-00 to 04-Feb-00)
                               

Similar to last week, we have only one KSC pass on Thursday, so we will
not attempt a table upload.  We do not intend to make more than one upload
per day.  There are no campaigns planned for this week.  Saturday is a
Yohkoh holiday. 

Hugh Hudson will be the SXT_CO during Week 00_06.

The * on Friday means that the UT date of the upload does not match the
JST date.

Continuing requests:

KSC & SSOC Tohbans: If any KSC passes are likely to be cancelled (for
example due to heavy snowfall) or an SXT table cannot be uploaded for some
reason, please telephone and e-mail the Chief Observer immediately.
(sxt_co@isass0.solar.isas.ac.jp, copy to sxt_st@flare2.solar.isas.ac.jp).

KSC Tohbans: In general flare mode supersedes table upload, i.e. if a
flare is in progress please do not upload a new table, and contact the
chief observer. Normally it is OK to go ahead with the planned table
without change on the next pass, if it is available. Chief observers
should keep an eye on this.
