CHIEF OBSERVER'S REPORT for Week 7 12-Feb-01 through 18-Feb-01 H. Hudson GENERAL Dead quiet solar conditions continue; still no M's or X's. SXT TECHNICAL No problems. SXT SCIENTIFIC For Web material see the science nuggets: Current Week: http://isass1.solar.isas.ac.jp/sxt_co/010216.html Index: http://isass1.solar.isas.ac.jp/sxt_co/index.html The newest nugget, "A million-kilometer jet," describes a large-scale coronal event observed by Ilia Chertok (IZMIRAN). It is perhaps a large double-sided jet, according to the Shibata-Shimojo classification. On the other hand, perhaps this is a filament-channel activation event, without an eruption. Or perhaps these are two descriptions of the same thing, please judge for yourself. It is in any case beautiful. CAMPAIGNS No campaigns during the interval and none planned at present. We remain on the alert for sigmoids as a "target-of-opportunity". 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 H. Hudson left on 17th. N. Nitta arrived on 19th. SEMINARS D. P. Choudhary (PRL): "Flows in the Active Region" TELEMETRY DOWNLINKS We hereby cease listing telemetry downlink statistics. The SSOC tohbans will take over this task. SXT TABLE PLAN, WEEK 8 (19-Feb-01 through 24-Feb-01) A quiet-Sun campaign will run for three days (20,24,25) this week. We don't have details of the times yet, nor do we know about activity of course, so the tables below are place-holders. ________________________________#_______________________________ JST Day UT Start Time Pass Table ID Saturday PM 17-FEB-01 11:37 3 010217 P3 ARS1 STD Monday PM 19-FEB-01 11:43 3 010219 P3 ARS1 STD Tuesday PM 20-FEB-01 06:42 1 010220 P1 ARS0 QS Tuesday PM 20-FEB-01 11:46 4 010220 P4 ARS0 QS-DIF Wednesday PM 21-FEB-01 06:44 1 010221 P1 ARS1 DARKCAL Wednesday PM 21-FEB-01 11:49 4 010221 P4 ARS1 STD Thursday PM 22-FEB-01 08:28 2 010222 P2 ARS1 STD Friday PM 23-FEB-01 08:31 2 010223 P2 ARS1 STD Saturday 24-FEB-01 05:11 1 010224 P1 ARS0 STD The date part of a table ID reflects the UT date of pass 1. A '*' signifies that the date of the table ID does not agree with the JST date of the pass in question. 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 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.
