To be run as a target of opportunity study between
December 2000 and April 2001. The Yohkoh SXT chief observer will
alert the members of this JOP whenever a sigmoidal active region is seen
in the East, providing target information and suggested times for coordinated
observations. Observations of the region will then be taken as the
target transits the solar disk, with particular attention to +/- two days
of central meridian passage, and two or three days as it passes the West
limb.
This JOP will be run in conjunction with Max Millenium Observing Program: MM0P11
