CHIEF OBSERVER'S REPORT for Week 08 13-Feb-00 through 20-Feb-00

GENERAL

Solar activity was moderately high, with M's but no X's. A MacIntosh alert predicts major flares from 8869 (SW) and in fact an M2 is happening now (Monday morning JST) - alas for the Macintosh prediction (about seven hours prior to the event), no protons.

SXT TECHNICAL

HXA was off for two days owing to a mis-command at KSC. Accordingly there will be no SXT pointing information for (approximately) 17-Feb 18:00 to 19-Feb 19:00. As usual, please confirm (att.status1 eq 8) for good solutions.

We obtained two days' worth of "rapid-run" Q resolution SFRs this week.

The science nugget this week introduces the Grand Archive of Flare Cartoons, which aims to make all of the significant sketches of flare theoretical scenarios available on the Web.

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.
