CHIEF OBSERVER'S REPORT for Week 30 
                      23-Jul-01 through 29-Jul-01 

                        H. Hudson, A. Takeda

GENERAL 

The solar activity was low during the week, with not even an M-class flare
to boast about (maximum was C7.8).  The SXT bakeout was successful.

SXT TECHNICAL 

No new problems to report. The bakeout resulted in a slight decrease
of dark current. The next bakeout should be done in November, schedule
permitting.

SXT SCIENTIFIC

This week's nugget looks at a group of magnetic regions clustering
together into a sort of giant anemone-type structure. This structure
does not seem to connect either across its boundaries, all of the
same-polarity coronal hole, or outwards into the solar wind as a
streamer.

CAMPAIGNS 

On Monday we had our last joint observation with JOP 100.

The date part of a table ID reflects the UT date of pass 1.
A '*' means that the UT date of pass 1 differs from the JST date
of the pass in question.
 
This table plan is likely to change.  Prepare for last minute changes.


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.
