CHIEF OBSERVER'S REPORT for Week 7
                      12-Feb-01 through 18-Feb-01 

                             H. Hudson 

GENERAL 

Dead quiet solar conditions continue; still no M's or X's.

SXT TECHNICAL 

No problems. 

SXT SCIENTIFIC

The newest nugget, "A million-kilometer jet," describes a large-scale
coronal event observed by Ilia Chertok (IZMIRAN). It is perhaps a
large double-sided jet, according to the Shibata-Shimojo classification.
On the other hand, perhaps this is a filament-channel activation event,
without an eruption. Or perhaps these are two descriptions of the same
thing, please judge for yourself. It is in any case beautiful.

CAMPAIGNS 

No campaigns during the interval and none planned at present.
We remain on the alert for sigmoids as a "target-of-opportunity".

                     SXT TABLE PLAN, WEEK 8 
                  (19-Feb-01 through 24-Feb-01)

A quiet-Sun campaign will run for three days (20,24,25) this week.
We don't have details of the times yet, nor do we know about activity
of course, so the tables below are place-holders.

The date part of a table ID reflects the UT date of pass 1.
A '*' signifies that the date of the table ID does not agree with
the JST date of the pass in question. 

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.
