SOT shift report 2003-03-20 L1337 Written at 2003:079:14:23 UTC = 09:24 am Mar-20-2003 EST End 11:00:00 AM EST SOT Lead: Ed Kellogg PLAN ---- OBSID 04198, RDCS1252-29 2003:079:10:43, ACIS-I NONE - A MASSIVE CLUSTER AT Z=1.235. RADIATION SUMMARY ----------------- Solar soft proton flux is High. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity yesterday: Solar flare activity was high.(http://www.dxlc.com/solar/) CMEs reported for past two days: March 17: A possibly geoeffective CME may have been associated with an X class flare. March 18: A fast CME, probably with a geoeffective extension, was observed after the X1/1B flare. This CME will likely reach Earth on March 20 and could cause unsettled to minor storm conditions. March 19: A full halo CME was observed early in the day with the major part of the ejected material seen below the south pole. The source of this CME was likely backsided. (http://www.dxlc.com/solar/, Jan Alvestad) The March 19 CME, being backsided, may not reach Earth.

B products will be out shortly for email review today. S/C: Eric ran an ASVT test yesterday, on a mini RTF that helps us check the VC2 channels for the DSN automation evaluation. The test went fine. Leon presented our proposal to NASA yesterday for moving the ASVT to the OCC. MSFC will probably not be staffed for the next couple of days due to the world situation. GOT/IST: - DATA:- SOT: GOES x-ray flux: One C class short duration event at ~12:00 UTC today.
