CHIEF OBSERVER'S REPORT for Week 25
                      17-Jun-01 through 23-Jun-01 

                              D. McKenzie

GENERAL 

Solar activity was higher this week, with 4 M-class and 1 X-class flare.  
Most of these flares occurred on Saturday (JST), but the X-ray background
stayed above GOES C level for almost the entire week.  The highlight was
the solar eclipse on Thursday, in which SXT observed two partial eclipses.


SXT TECHNICAL 

After testing and refining the HESSI-support flare table last week, we 
shelved it this week; we have returned to a flare table designed for 
observing ejecta, waves, and inflows.  We also returned the FFI table to 
an equal balance between AL.1 and ALMG images.  Pointing was very steady 
this week.

This week's nugget shows -- what else? -- the solar eclipse of June 21.


CAMPAIGNS 

No coordinated campaigns are planned for this week.

PERSONNEL

No personnel changes this week.


SEMINARS

The seminar this week was given by Hugh Hudson, regarding a 
far-behind-the-limb flare from April 18, 2001.  Nobeyama and HXT both 
tracked moving sources with speeds near 950 km/s.  Are they the same 
source?

The date part of a table ID reflects the UT date of pass 1.  The "*" in 
the table ID indicates that the JST date of the upload is different from 
the UT date of Pass 1.

This table plan is likely to change.  Prepare for last minute changes.

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.
