SXT TABLE PLAN, WEEK 50 (04-Dec-00 to 09-Dec-00)

A SoHO/CDS campaign, named VELAR, has been proposed by K. Hori, and we will cooperate with it(4 to 9 Dec). They will observe an active region, especially forcusing on its velocity distribution. There are two table uploads planned for Tuesday and Thursday.

!!! Note that we have changed some of the table names given in the draft, since the details of the campaign have been fixed.!!!

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.
