CHIEF OBSERVER'S REPORT for Week 40
 
                        25-Sep-00 through 1-Oct-00

GENERAL 

During the last part of the week, flare activity increased, and a long-
awaited X-class occurred in the giant region AR 9169, unfortunately not 
in the JOP 104 target region.

SXT TECHNICAL 

No problems.

SXT SCIENTIFIC

For Web material see the science nuggets:

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

The newest nugget discusses loops that apparently shrink with time, which
were first documented by Wang et al. (1997) on the basis of SXT observations.

CAMPAIGNS 

JOP 126 ended, and JOP 104 continued.

                     SXT TABLE PLAN, WEEK 41
                      (2-Oct-00 to 8-Oct-00)

JOP104 continues, but we may not actively cooperate with the campaign
unless there is a more promising region coming up on the east limb than
regions elsewhere.

This table plan is subject to change. 

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.
