FRIDAY — 11 January 2002

————————-

	* MDI will uplink a tuning and focus load for 60-day

	  continuous (allow uninterrupted 1 hour and 15 minutes)
MONDAY — 14 January 2002 — Instrument Safing

———————————————–
 	*** Limit violation sheets need to be in by 4pm local
DSS-66	07:40 – 15:25 UT
DSS-27	15:05 – 00:05 UT
	* UVCS safing at 20 UT
        * LASCO closes doors at 22 UT
DSS-46 	23:45 – 06:00 UT
        * CDS closes door after 24 UT 
TUESDAY — 15 January 2002 — Maneuvers

—————————————–

DSS-54	08:15 – 12:20 UT

	SVM Reserved for Step 2 of Maneuver Prep

          (Cat Bed heaters ON), only takes about 5 minutes

	NRT could be made available very early if necessary.
DSS-16	15:00 – 00:20 UT

	SVM Reserved Time for Maneuvers
        * Instrument Activities done by FOT

	  – FOT has SOC notify MDI and opens MDI’s ISS loop

          – Remove SWAN from ESR warning flag receiver list

          – SWAN Safing

          – Disable offpointing flag function for LASCO, MDI, UVCS 
        SVM Reserved Continues – First burn at 16:30 UT

        * Maneuvers – SK (5.5 minutes burn) then MM (total of 75 minutes,

	  done in 3 segments of varying lengths)
        * Instrument Recovery activities done by FOT

          – Re-enable offpointing flag function for LASCO, MDI, UVCS

          – FOT has SOC get clearance from MDI and then closes

		MDI’s ISS loop via TSTOL

          – Recover SWAN (2 hours after last thruster firings)

            via usual TSTOLs

          – Return SWAN to ESR warning flag receiver list
                * After SWAN recovery, the delayed command file

                  SWA02_________.DEL science load should be uploaded.
  ~21-22 UT FOT should be done
	* 23 UT UVCS may recover (~45 minutes, pauses tolerated with warning)

		  or on DSS-27 Wednesday
WEDNESDAY — 16 JANUARY 2002

—————————

DSS-46	02:45 – 06:10 UT
DSS-66	07:55 – 15:10 UT
DSS-27	15:05 – 00:25 UT
	* If UVCS has not recovered, they will recover on DSS-27

	    (~45 minutes, pauses tolerated with warning)
THURSDAY — 17 JANUARY 2002

—————————

DSS-46	00:25 – 07:50 UT
	* CDS will open doors on D46 (~5 minutes)
DSS-66	07:40 – 15:40 UT
DSS-16	15:20 – 00:25 UT
	* LASCO will open doors at 16 UT
	* EIT Shutterless observations 17:00-19:40 UT
DSS-46	00:05 – 07:50 UT
