SSOC Tohban Report for Week 49, 1993 (06 December - 12 December 1993) K. Suga, K.Yoshimura (SSOC) Y. Suematsu, H.Watanabe (KSC) 1. Solar Activity The solar activity is again low, with the largest flare being C9.7. 2. Standard Operations 2.1 SXT Table Uploads: JST UT (Tue)07-Dec 931206 T1 P2 ARS1 DKCAL (Wed)08-Dec 931207 T1 P2 DEEP CORONA 931207 T2 P4 ARS1 STD (Thu)09-Dec 931208 T2 P4 ARS1 STD 2.2 STT Timer Set The STT timer was set (ie. restarted ) on Dec.10 (Fri) 1'st Pass. But this set had only 15 minutes "STT use" status. Then, we had arranged STT timer set on Dec.13(Mon) 2'nd pass ("STT use" status is 30 minutes). And we did not check the STT track, because STT timer set on week end. 2.3 Weekly Offset Pointing The 8' deep corona data offset pointing was performed on Wednesday, 8-Dec. Pass2 : S/C offpoint E(8') , Pass3 : S/C Offpoint W(8'), Pass4 : S/C normal point 3. Special(?) operation On Wednesday, midnight 1'st KSC pass(ID:931208-0929) was canceled for year end of party at KSC. (Watanabe_Te-san accepted this.) We had only 4 KSC passes on that day. 4. DSN communications As we used full of 2 pages of the "DSN communication LOG notebook", we had a many communications with JPL. The first half of this week, DSN final schedule was changed many times due to shuttle supports. Thanks J_Lemen-san for help us. 4.1 DSN data (DSS16 DOY336(02-Dec-93) 1421-1431) have not yet arrived, and we asked Joe_Espinueva-san for it on Friday, 10-Dec. by FAX and ` RASM. But the answer has not yet come. 4.2 We had a lot of question about Goldstone DOY319(15-Nov-93) P/B data and stranger data. 5. Problems, Errors and Accident 5.1 SXT bit map error was found on (Tue)06-Dec. morning 5'th pass. And it was cleared by "YOBI commands C". 5.2 On 9-Dec at Pass1 mis-commanding was occurred. Commander mistook "TMS-H-REP" for "TMX-H-REP". So they couldn't completely reproduce BDR in the Pass1. The remnant data was received at Pass2. 5.3 The display of Flare1 was recovered. We could not make sure of the cause. (Suga_san only turned the display on. It worked normally. Was it really broken?) 5.4 Last week tohban did not get the revised final schedule (SOLASS.W49;3 Ver.06, DATE:03-Dec-93) from RASM in spite of they had a chance to get it on Sat,04-Dec. Then, YOHKOH had not contacted twice in spite of DSS66 had prepared. 6 .
