  GENERAL

  The 8 arc min. E/W offset pointing was done on 27 Jan (UT).

1. Solar Activities

	Solar activity increased because AR 7654 reactivated.
There were a series of M flares in the GOES data, shown on the
activity summary below.

   
2. Standard Operations

2.1 SXT Table Uploads
                Pass             ID
  (Tue.) 25-Jan  #4  "940125 T1  P4  ARS1 DKCAL"
  (Wed.) 26-Jan  #2  "940126 T1  P2  ARS1 STD"
  (Thu.) 27-Jan  #1  "940127 T1  P1  DEEP CORONA"
                 #4  "940127 T2  P4  ARS2 STD SCAT"
  (Fri.) 28-Jan  #1  "940128 T1  P1  ARS2 STD SCAT"
  (Sat.) 29-Jan  #2  "940129 T1  P2  ARS1 STD"

2.2 STT Timer Set

  STT timer was set at pass 2 on Jan 25.  
  The next timer set should be done on Feb 2.

3. Special Operations

	a) SXT West offpoint was continued for 2 orbits because
	of the active region on the W limb.  The flare with CME
	occurred on the day after the offpoint but was observed
	on several KSC orbits.

	b) Acton's special flare table for measuring the SXT
	mirror scattering during a flare was successfully
	run and observed at least 2 flares.


4. Offset pointing

  The 8' east/west offset pointing was done from pass 1 to 4 on Jan 27.
 
  (Thu.) 27-Jan  #1 (940127-0929)    east 8 arcmin (ROG #23h)
  (Thu.) 27-Jan  #2 (940127-1033)    west 8 arcmin (ROG #24h)
  (Thu.) 27-Jan  #4 (940127-1240)    normal point  (ROG #20h)

5. Errors and problems

  SXT errors   
	Tues.  Pass 1   Bit map error

  BCS errors
	Wed.   Pass 4   
	       Pass 5   Error 5
	Thu.   Pass 1
	       Pass 2   recovered

  DSN interaction
	ISAS gateway went offline on Jan 29 and Jan 30.  


	Sunday is a KSC day off.  Please be careful to keep extra
	passes on the Strawman DSN schedule.  Our first
	OP for Saturday-Monday had 23 hours of Quiet Medium operation
	because we had only 2 DSN passes on the KSC day off.
	We requested and received 3 DSN passes that had been deleted
	from the Strawman.  These added 8 hours of High data rate.
	This problem can happen when DSN cancels passes that we 
	requested.  The passes we deleted may still be available.


6. Hikitsugi

	FACOM password must be changed on Feb 1.

	The launch of the H-2 rocket will occupy tracking facilities
	this week.  To provide tracking of Yohkoh, they will work
	on Sunday.  The weekend OP should include passes
	940206-07xx and 940206-08xx at High rate for this tracking.


  The next tohbans in week 05 are
    * SSOC 	Ishido, Sterling
    * KSC 	Kozuka, Shimizu
