Plan to come and bring something to grill+drink. Directions to the park are available at: http://esa.nascom.nasa.gov/~bfleck/Cabin_John/ Hope to see you Sunday! FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: VIRGO Planned Activities: 6-day RSL, VIRGO, SWAN Nominal HGA Table Upcoming Operations: 6/24-6/29 Maneuver Operations Ground Anomalies: 169/1239 TM Dropout; D66 antenna drift (1 min, unrecoverable) 169/2318 TC anomaly during LASCO NRT (6 min delay) 170/0013 Resweep required for ranging at D46 (9 min delay) 170/0021 TM Dropout; D46 rcvrs lost lock (1 min, unrecoverable) 170/0955 Resweep required for ranging at D66 (5 min delay) 170/0938 IRTS unable to send TM to EOF (4 min, recoverable) INSTRUMENT STATUS ----------------- EIT Nominal. Bakeout continues through the weekend. LASCO Nominal. H-alpha study during EIT's bakeout. CDS Nominal. Synoptics, active region and explosive events today and through weekend. JOP016 and occilations study on weekend and off-limb coronal study Sunday. UVCS Will observe at 6.5 Rsun on weekend. MDI High res active region study continues. Saturday will switch to 3/4 full disk for active region belt and filament in South. TRACE Subflares in C IV images are very pretty. Some 171 imaging not done because subflares triggered some limits. Also, increased cadence to 15 seconds. Explosive events and quiet sun until 22:30 today. Filament study tomorrow. SUMER Nominal. SUMER plans shown below.
