Web Page for Planning: http://www.bbso.njit.edu/arm INSTRUMENT STATUS ----------------- CDS: Nominal. JOP137/104 continues on AR9901/9893. Tomorrow: same but also engineering studies. SUMER: Nominal. JOP137/104 continues on AR9901/9893. UVCS: Nominal. 24-hour synoptic. Tomorrow: JOP155 and mini-synoptic. LASCO: Nominal. C2/C3 synoptics. EIT: Nominal. Half-resolution 195 CME watch and synoptics. JOP155 support begins tmorrow with subfields in north. MDI: Nominal. Full disk magnetograms and dopplergrams for continuous contact, supporting Sac Peak campaign. CEPAC: Nominal. Observations near solar maximum as opposed to solar minimum has shown that high-energy particles are accelerated both by flares and CME shock fronts, and the two signatures are often mixed. Also, in flares, electrons seem to be accelerated a little earlier than protons. TRACE: Nominal. Today we continue support in high-cadence 195 for RHESSI, JOPs 104/137 and observations at Sac Peak (AR 9907).
