Relevant Notes

————–

CDS:	Full Sun (USUN) on Monday, various active region studies

        throughout the week, usual weekend studies.
UVCS:	Cassini conjunction observations and synoptic, possible RHESSI

        observations during weekend if suitable target exists, otherwise

        coronal hole and synoptic observations.
LASCO:	C2/C3 synoptics, JOP159 Wednesday – Friday.
EIT:	195 CME watch and synoptics.
MDI:    Switching to full disk magnetorgams and dopplergrams on

	Monday. Tuning reload and possibly a change to normal focus

	(from full disk best focus) on Friday. Campaign testing and

	calibrations possible on Friday also.
TRACE:  Active region studies.
