Yohkoh/SXT Campaign Planning Notes are no longer at this location. We've switched to a Web-based system. Please see our weekly plan, listed at
http://isass1.solar.isas.ac.jp/sxt_co/SXTweekly.html
For records of joint observing campaings that are currently planned, see
http://isass1.solar.isas.ac.jp/sxt_co/sxt_future.html
and for records of old campaigns, see
http://isass1.solar.isas.ac.jp/sxt_co/sxt_catalog.html
Finally, for our science notebook/journal/newspaper, see
http://isass1.solar.isas.ac.jp/sxt_co/index.html
and the "science nuggets" found in past weekly reports. Science nuggets are reformatted and cleaned up by the MSU group. These nuggets can be found at

SXT_CO (sxt_co@isass1.solar.isas.ac.jp)
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 http://www.lmsal.com/SXT/homepage.html and http://solar.physics.montana.edu/YPOP/
