Weekly SXT Report for Week 01

CHIEF OBSERVER'S REPORT for Week 1 1-Jan-01 through 6-Jan-01

Hugh Hudson

GENERAL

This is the first SXT report since the New Year's holiday. Activity was low, with no M flares since the holiday began Dec. 29.

SXT TECHNICAL

SXT returned from the holiday in an error state (normal SEU; cleared immediately). At the time of writing we can't tell when the error occurred. We've resumed normal (5-line sequence) flare table as of the beginning of this year, since our special scattering table seems to have accumulated a lot of data.

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.

A '*' means that the UT date of pass 1 differs from the JST date of the pass in question

This table plan is subject to change.

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).
