May 12-14: IPS Measurements. During the IPS study, EIT will have regular synoptics along with half resolution 195 CME watch. On 2005/05/03 @ 19:06 UT SOHO Telemetry Submode changed to Submode 6. It will be in Submode 6 until 2005/05/16 @ 12:00 UT. During that time, EIT 195 CME watch at full resolution (1024x1024).
03:52 UT E Limb Jet-like front. 04:52 UT WN West Diffuse and ragged front that fades throughout C2. 06:22 - 11:22 UT NO LASCO C2 Data due to IPS "C3 only" timeframe. 14:22 UT S West Diffuse loop front that fades throughout C2. 17:52 UT NN West Expanding diffuse loop front. It fades throughout C3. 21:52 UT N Pole Jet-like front developing slightly toward NNW. 23:22 UT E Limb Wide and diffuse fan-like front. 23:22 UT NN West Diffuse loop front developing like pushed toward S.
04:52 - 09:52 UT NO LASCO C2 Data due to IPS "C3 only" timeframe. 17:22 UT All around Nice and bright Full Halo CME. GOES reported a long duration X-ray event (M8.0) from NOAA AR 10759 (N12E11) between 16:13 - 17:28 UT with peak emission at 16:57 UT. EIT images show the presence of an EIT wave and dimming. A proton event follows. 17:50 - 22:50 UT Non-recoverable LASCO Data Gap (C2 times) due to LEB (LASCO Electronic Box) crash.
