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: Current Week: http://isass1.solar.isas.ac.jp/sxt_co/000721.html Index: http://isass1.solar.isas.ac.jp/sxt_co/index.html "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. For SXT plans, see: http://isass1.solar.isas.ac.jp/sxt_co/sxt_future.html For SXT completed campaigns, see: http://isass1.solar.isas.ac.jp/sxt_co/sxt_catalog.html PERSONNEL Hudson returned to ISAS; Handy returned to the U.S. SEMINARS None.

There will be a SERTS rocket flight July 26, in conjunction with VLA observations July 27 and 30 in JOP 100 (DEM). ________________________________#_______________________________ JST Day UT Start Time Pass Table ID Tuesday AM 24-JUL-00 19:22 4 000724 P4 ARS1 DIFF* Tuesday PM 25-JUL-00 14:24 2 000725 P2 ARS1 DARK* Wednesday AM 25-JUL-00 19:30 5 000725 P5 ARS1 STD* Thursday AM 26-JUL-00 16:13 3 000726 P3 ARS2 SERTS* Thursday PM 27-JUL-00 12:57 2 000727 P2 ARS2 VLA* Friday PM 28-JUL-00 13:04 2 000728 P2 ARS1 STD* Sunday AM 29-JUL-00 14:54 3 000729 P3 ARS2 VLA* * The ID reflects the UT date of the first pass. 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.
