active region belt in the northern hemisphere, much of which is now
drifting over the west limb.

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.
