CHIEF OBSERVER'S REPORT for Week 38 11-Sep-00 through 17-Sep-00 N. Nitta, A. Takeda GENERAL Higher activity than the previous week. A total of five M-class flares occurred during 14-16 September. Except for the first one, which came from AR 9166 (the target region of JOP 126), these flares were produced in a rapidly growing region AR 9165. We had thunder storms from typhoons, which damaged the power supply of an important disk drive. This is now fixed by Brian Handy. SXT TECHNICAL No problems. SXT SCIENTIFIC For Web material see the science nuggets: Current Week: http://isass1.solar.isas.ac.jp/sxt_co/000915.html Index: http://isass1.solar.isas.ac.jp/sxt_co/index.html The newest nugget rehashes the Bastille Day flare with beautiful HXT images provided by S. Masuda. CAMPAIGNS We continued to take strip images 1024x256 at full resolution for JOP 126. We switched to the fast QR cadence when JOP 104 started.

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.
