CHIEF OBSERVER'S REPORT for Week 30 
                       17-Jul-00 through 23-Jul-00

                           H. Hudson, B. Handy

GENERAL 

Activity remained high, with innumerable M-class flares, but no X's
since July 14. There are many active regions on the Sun now, with
many many spots. 

SXT TECHNICAL 

SXT worked fine without apparent problems this week.  The CCD bakeout 
planned for last week was postponed because of the high activity.
We will wait for an opportunity. 

SXT SCIENTIFIC

For Web material see the science nuggets:

"Cusps upon cusps"
  Successive major flares in the same active region left different
  cusp structures - in other words, the second event apparently 
  restructured the field from the configuration just established
  the day before. The opposite kind of behavior had been reported
  in a science nugget a couple of months ago, so we continue to be
  surprised.


CAMPAIGNS 

None.

                      (24-Jul-00 - 29-Jul-00)

The high activity precludes baking-out. There will be a SERTS
rocket flight July 26, in conjunction with VLA observations
July 27 and 30 in JOP 100 (DEM).

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.
