CHIEF OBSERVER'S REPORT for Week 36 
                        27-Aug-00 through 3-Sep-00

GENERAL 

Activity remains low - the "major" flare of the week was a C9.1 on 
September 1. The special flare mode we are running, which emphasizes
long-exposure full-resolution 2x2 images, did not show any ejecta
in spite of reports of Type II and Type III bursts.

SXT TECHNICAL 

SXT had no technical problems this week. A new normal pointing should
be carried out on Monday, Sep. 4. The new FFI table seems to work quite
well and we propose to leave it in - recall that this provides sets of
six AlMg SFD-type images at two-minute cadence. It seems to show faint
coronal phenomena much better than the old standard. 

The special flare table has now caught about three events, two ejective.
The event of August 25 turned out to meet the campaign aims spectacularly
well - TRACE detected oscillations, and Yohkoh detected a nice ejection
that matched a decimeter Type IV event well. See this week's science nugget.

This week will see the flight of the TXI rocket ("Tunable X-ray
Imager" most likely) on Sep. 5. We will probably continue the
rapid FFI and deep flare-mode tables for this week. We expect
a flare during the rocket flight, because Golub claims to be
invariably successful in catching flares with rocket launches.

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.
