INSTRUMENT STATUS
-----------------
CDS: Nominal. Today - JOP118, JOP140 and lubrication study (18:30-21 UT).
Weekend - Energetic events study on quiet sun region in the far
south, CME watch on west limb and other CDS weekend studies.
UVCS: Nominal. Coronal hole observations in the south west and synoptics.
LASCO: Nominal. C2 and C3 synoptics.
EIT: Nominal. 195 Angstrom CME watch and synoptics.
MDI: Nominal. Cropped full disk magnetograms and dopplergrams in
best focus for continuous contact.
TRACE: Nominal. Today - Mostly AR 9433 again, supporting TRACE goals and
JOP 140. However, we will take a short excursion to AR 9436 on
behalf of CDS for JOP 118 (sunspot oscillations). TRACE will observe
AR 9433 all weekend.
