                         SXT TOBAN REPORT,  WEEK 51

                                 Hugh Hudson



1. Background. Activity at Sagamihara this week did not include any
real-time operations, which have now been transferred to KSC. The SXT
toban's function has therefore been combined with that of the SSOC toban.
This worked fine. This week was quite effortless in terms of problems.

2. SXT health. There were no problems with quiet mode data. There were no
flare-mode flares in KSC playback or real-time data.
     There are 7 flare-mode events currently in the data base for Week 50.
During each of these the patrol function was correct. All were at either E or
W limb, incidentally.

3. Table changes. There were three table uploads during Week 51: 

Dec. 17. Add long exposures (executed by the KSC toban)
Dec. 19. Remove long exposures for weekend operations.
Dec. 21. Add long exposures.

4. State of Solar Activity. Low. There were no KSC flare-mode flares during
Week 51, although according to GOES there should have been some in the DSN
data. The largest flare this week was below the M level.
     There were some fascinating developments in the organization of active
regions and coronal holes. A weak diffuse transient was seen in the N polar
region.

5. Hikitsugi.  The new system makes light work for the SXT toban. I recommend
that they continue with the routine tasks that are remaining, and use the
extra time to verify correct flare-mode operation in recent weeks for which
complete reformatted data rea available. Then, they can do science at will.
     The KSC playback for Dec. 21 are not available yet. The reason for this
is under investigation.
