The OCC has minimum staff present. The 9 o'clock meeting was held by telecon. OBSID 04419 0 RX J1914.4+2456 2003:049:11:31:21.930 13.8 ACIS-S NONE - TIMING THE ORBIT OF RX J1914.4+2456: GRAVITATIONAL RADIATION AND THE NATURE OF THE X-RAY EMISSION. RADIATION SUMMARY ----------------- Solar soft proton flux is Low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity yesterday: Solar flare activity was low. Two C class events were recorded during the day. A long duration C1.0 event peaking at 11:29 UTC had its origin behind the southwest limb, while a C1.9 flare at 17:29 had a source behind the northwest limb. (http://www.dxlc.com/solar/) CMEs reported for past two days: February 15-17: No obviously geoeffective CMEs observed. February 18: A large filament eruption in the northwest quadrant (near the northwest limb) was observed beginning at 01:55 UTC. This eruption was associated with a CME off the northwest limb, the CME will probably not have any geoeffective extensions.
