8 July 1996 Serge Savy SXT CHIEF OBSERVER REPORT AND TABLE PLAN SXT CHIEF OBSERVER'S REPORT for Week 27: 01-JUL-96 to 07-JUL-96 The easiest way to eat crow is while it's still warm. The colder it gets, the harder it is to swaller. from `A Cowboy's Guide To Life' SOLAR ACTIVITY Solar activity was low, although there were several small active regions on the disc. A large swathe of diffuse corona extending across the disc appeared during the week, and has persisted for several days. SXT INSTRUMENT STATUS No significant SXT errors errors. SXT continues to function well. CAMPAIGNS No campaigns in week 27. SEMINARS On Thursday, July 4, there were several speakers during the regular seminar period: S. Savy (ARC/ISAS) "Soft X-ray preflare brightening" A. Sterling (CPI/ISAS) "BCS results from Madison" B. Somov (MSU/NAO) "On the thermal instability of shrinking loops" NEW REFORMAT DISC The reformat data area is now located on /yd3/reformat on isass0, following the problems with the isass2 disc last week. This is the new /yd3 automount point: /yd3 isass0:/isass0data5:yohkoh /yd3 isass0:/isass0data5:yohkoh SXT TABLE PLAN FOR WEEK 28 (8-Jul-96 to 13-Jul-96) This week we are doing coordinated oberservations of the corona over the east limb with SoHO on 8 July, using a special long exposure full resolution FFI table. This table will run overnight on 8 July. A dark calibration table will be loaded on Tuesday, and the weekly diffusers included as part of a standard table on Wednesday.

SSOC TOHBAN, please fax the preliminary OP list to D-tou when it contains a terminator so that the Chief Observer can suggest which OG's to use.
