CHIEF OBSERVER'S REPORT for Week 37 
                        4-Sep-00 through 10-Sep-00

                           H. Hudson, A. Takeda


GENERAL 

Activity remains low, but there were at least two M-class flares.
We are still running the special flare-mode table with 2x2 FR images.
It works well.

SXT TECHNICAL 

No problems.

SXT SCIENTIFIC

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

The current nugget deals with a beautiful pre-flare, flare, flare ejection, 
CME event of Sept. 7. Quite a nice event.

CAMPAIGNS 

We supported the TXI rocket (SAO tunable X-ray imager). It flew on
schedule, but its SPARCS system (pointing) failed - no data. This week
we have also been running in support of JOP126 on coronal loop
temperature structure.  For this purpose we've been getting strip
images 1024x256 at full resolution. JOP104 starts on September 15, to
stydy the onset of flare-CME events.

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.
