Rerun of sigmoidal active region study (SOHO/TRACE JOP 106)


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
