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.

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.

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.
