CHIEF OBSERVER'S REPORT for Week 47
                      19-Nov-01 through 24-Nov-01

                          D. McKenzie, J. Sato   


GENERAL 

Flare activity was higher this week, with many C flares, and three M
flares (almost X, at M9.9).  We followed active region NOAA 9704 during
the latter part of the week, as part of a Sigmoid Target of Opportunity
campaign; the region produced one slow LDE (C-class) on Thursday, and two
M flares on Friday.


SXT TECHNICAL 

We returned the flare table to 1x1 PFIs this week, with AlMg and Be
filters, and three resolutions in the AlMg images.  Unfortunately, we got
no images of the M flares due to an electronics hangup in SXT.

This week's nugget describes the sigmoid campaign on NOAA 9704, which 
produced some geoeffective eruptions.


CAMPAIGNS 

No official campaigns were planned to support, but we ran a Target of 
Opportunity campaign for the sigmoid in NOAA 9704.

The date part of a table ID reflects the UT date of pass 1. An
asterisk means that the ID's date number differs from the upload 
date in JST. 

This table plan is likely to change. 
Prepare for last minute changes, even with naming conventions.

Continuing requests:

KSC & SSOC Tohbans: If any KSC passes are likely to be cancelled (for
example due to typhoons) or an SXT table cannot be uploaded for any 
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.
