Yohkoh/SXT Campaign Planning Notes
SXT Chief Observer: Nariaki Nitta (sxt_co@isass0.solar.isas.ac.jp or nitta@isass0.solar.isas.ac.jp)
See the bottom of this file for a tentative Chief Observer schedule in coming weeks.
SXT is currently functioning normally, observing the eastern limb (N08).
SXT current status and plan for the week:
KSC Time (start) in JST Pass Table ID
Tuesday 12-NOV-96 20:40 2 961112 P2 ARS0 STD+LONG
Wednesday 13-NOV-96 22:42 4 961113 P4 ARS0 STD+LONG

See the WWW information for full details at More Information. This includes last known SXT pointing coordinates as well as comments regarding Yohkoh and solar status.
Notes: The SXT flare mode currently emphasizes ejecta. By comparison with the standard flare table, we have reduced the number of filters at high resolution and have increased the cadence of half resolution AEC image, including two filters. The result should be an image pair every 30 sec or so. HXT flare mode is normal. As of 21 October, we are not taking the short members of the standard movie image pairs, thus increasing the frequency of long exposures and SFD's.
CME Onset Study (JOP 3, IACG 3)
Correspondent: R. Harrison
Purpose: Detect the onsets of CMEs
Dates: 11 November - 24 November
SXT setup: TBD, but probably like what we normally do unsuccessfully to catch filament liftoffs
Correspondents: Joe Davila, Roger Thomas
Purpose: spectral imaging of coronal structure. Disk center.
Dates: 13 November 1996, 18:30 UT
Correspondents: Gethyn Timothy (gethyn@jupiter.sun.csd.unb.ca) Paolo Bergamini (paolo@jupiter.sun.csd.unb.ca)
Purpose: Support of Gethyn Timothy's rocket.
Dates: mid-September 1996
Correspondents: S. Koutchmy, H. Hara
Purpose: similar to earlier study
Dates: Dec. 10-16 (tentative)
Dates: January 1997 (TBD)
Dates: April 1997 (TBD)
Dates: July 1997 (TBD)
Dates: October 1997 (TBD)
Correspondents: S. Tsuneta, T. Sakao
Purpose: Support of multilayer soft X-ray observations (Doppler)
Dates: February 1998
Additional information regarding these and other coordinated solar observations may be found on the WWW Selsis Campaign page at More Information.
The SXT instrument is a grazing-incidence soft X-ray telescope. See Tsuneta et al., Solar Physics 136, 37 (1991) for details. The options for an observing setup consist of where we look, how often we take exposures, what resolution they are in, what filters and exposure times, etc, etc. All of this is traded off within a fixed telemetry budget and various other constraints. For certain special operations we'll list some of this information here if we can. Otherwise please contact the SXT chief observer for whatever details are needed. e-mail to the "campaign" account is forwarded to the SXT Chief Observer.
The World-Wide Web has more to offer regarding Yohkoh and SXT. See More Information.
