SOT shift report 2003-02-24 L1313 Written at 2003:055:14:47 UTC = 09:47 am Feb-24-2003 EST End 11:00:00 AM EST SOT Lead: Ed Kellogg PLAN ---- OBSID 60834 CAL-ER 2003:055:12:44 then OBSID 03726, JUPITER 2003:055:15:59, ACIS-S NONE RADIATION SUMMARY ----------------- Solar soft proton flux is Very low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity yesterday: Solar flare activity was very low with no flares or even sub flares recorded. (http://www.dxlc.com/solar/) CMEs reported for past two days: February 21-23: No obviously geoeffective CMEs observed.

MP: We have three Jupiter observations coming up, coordinated with Hubble Space Telescope. The MAR0303 products will be out later today, with a review tomorrow. No momentum unloads are expected until 03 Mar. S/C: Gyro 1 roll is showing noisy bias and current, but no jogs. This is partly due to lots of short calibration observations of AR Lac recently, which don't allow the Kalman filter to settle down. Also, we've noticed similar behavior in the past, probably related to a release of lubricant, which can take ~ 1 month to settle down. We are not concerned, but are monitoring it closely. GOT/IST: - DATA: The data system choked up over the weekend on the large number of AR Lac calibration observations. SOT: GOES x-ray flux: No C class events today.
