2.  Science Operations


Active region observations concentrated on three targets: AR 9511, 9512,
& 9513 that were selected in conjunction with TRACE.

Mon June 25
-----------

Performed Full Sun and NIS/GIS spectral atlas studies, followed by
Polarity Reversal studies.

Tue June 26
------------

Performed flare diagnostic studies (ARDIAG_2 & SIG_FT44) on AR 9511 in
conjunction with TRACE. TRACE subsequently repointed from AR 9511 to AR
9513 because of low count rates. Following Polarity Reversal study, CDS
switched to observing the active region loop complex associated with AR
9513.

Wed June 27
-----------

Continued flare diagnostic studies of AR 9511 and 9513 in conjunction
with TRACE. Supported HESSI campaign observations of AR 9512, although
activity levels remained low.

Thu June 28
------------

Spacecraft maneuvers. No observations.

Fri June 29
-----------

CDS Filament engineering. No observations.

Sat June 30
------------

CDS Filament engineering. No observations.

Sun July 1
----------

Performed Explosive Events study. Supported SOHO/VLA Coronal Hole
Boundary campaign at coronal hole target in SE quadrant. 


3.  Instrument Status

On June 25, an NIS Setup Register A Failure System Error was detected.

On June 27, the NIS was reset at 22:34 UT.  Following the NIS reset, the
secondary (Science) processor was reset at 22:46 UT.  CDS doors were
then closed at 23:02 UT in preparation for S/C maneuvers.

GIS Filament Dumps were performed, from 15:00 UT - 23:45 UT on June 29.

On June 30, GIS Filament Dumps were performed from 15:30 UT - 19:40 UT.  


4.  Ground System Status
