26 August 1996 Serge Savy SXT CHIEF OBSERVER'S REPORT AND TABLE PLAN SXT CHIEF OBSERVER'S REPORT for Week 34: 19-AUG-96 to 26-AUG-96 SOLAR ACTIVITY Again a resurgence of the region (7978 - 7981 - ??) responsible for the X-class flare in July. The solar forecasters in Boulder missed the nice C-class flare (flares?) with LDE properties and a type II burst - they should have seen the AR coming two days beforehand thanks to our images! SXT INSTRUMENT STATUS Normal operation, no problems. CAMPAIGNS We continued the campaign to observe the large scale structure of the solar minimum corona with SoHO (JOP044). This campaign is coordinated by Sarah Gibson and Douglas Biesecker, and will last about one month, until 12-September. Details on SoHO JOP 44 can be found at http://sohowww.nascom.nasa.gov/operations/campaigns/soho/JOP044-199608.txt http://sohowww.nascom.nasa.gov/operations/JOPs/jop044.html SEMINARS No seminar last week. SXT TABLE PLAN FOR WEEK 35 (26-Aug-96 to 2-Sep-96) The coronal structure campaign (JOP044 with SoHO) continues this week with 3 special observing periods according to the following prescription: KSC visible orbits at S/C 5' W or E (nominal time frame UT 23:00 - 02:00). Long exposures (FFIs): Al.1 at 10 sec, AlMg at 30 sec SSOC Tohbans: The SXT CO will schedule the off-points for this campaign. The off-point plan for this week is: Wednesday 28-AUG-96 : S/C offpoint EAST 5' for last orbit before P4 Thursday 29-AUG-96 : " EAST 5' for orbit between P2-3 29-AUG-96 : " WEST 5' for orbit between P3-4 Friday 30-AUG-96 : " EAST 5' for orbit between P2-3 30-AUG-96 : " WEST 5' for orbit between P3-4 A dark calibration table will be loaded on Monday, and the weekly diffusers included as part of a standard table on Tuesday.

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.
