SOHO Telemetry Submode changed to Submode 5 on 2004/04/13 at 16:00 UT (SUMER began observing on 2004/04/14). SUMER campaign runs until 2004/06/17. In other words, LASCO synoptic observation plan cadence remains the same but the EIT CME watch images will be reduced to half-resolution (512x512) during that period.
10:50 UT ESE Limb Bright loop front and trailing material. Extremely faint extensions over the NW limb by 11:50 UT. Big signature of a barely backsided CME in EIT Fe XII running difference images above the ESE limb. Intensity disturbance seen traveling toward the S Pole all above the SE limb. Wave on disk by 11:12 UT. 15:06 UT W Limb Fairly faint 'legs' over the N and S Pole of an apparently very wide loop front. Loop front itself on W Limb barely visible. By 15:26 UT ragged front develops. Event could be associated with a C1.0 X-ray flare reported by GOES that occurred on NOAA AR 10605 (by the time located at S11W36) between 13:37 - 14:23 UT with peak emission at 14:03 UT. 17:26 UT NN West Ragged loop front. 18:50 UT N East Slow development of a system of loops along streamer. 21:26 UT E Limb Ragged asymmetric loop ('spray-like') front.
02:26 UT S Pole Asymmetric loop with a diffuse front. 10:26 UT N East Very faint front. By ~16:50 UT a fairly faint asymmetric front can be seen, one leg along the streamer, the other one close to the N Pole. 12:26 UT W Limb Spray-like front. 22:26 UT WS West Narrow ragged front. 23:26 UT S East Faint and narrow spray front.
00:26 UT N West Ragged front that fades close to the inner edge of C3. 05:26 UT N East Very small and narrow ragged front along the streamer that davelops as an asymmetric loop front. It is followed by a similar feature at ~12:06 UT. 08:26 UT S West Ragged loop front. 14:06 UT ES East Faint diffuse front followed at ~ 18:26 UT by a ragged front. Faint extendion over the E Limb up to the streamer on NE. 20:50 UT W Limb Spray-like front.
04:50 UT W Limb Wide and bright ragged lopp front with structured inner part. B1.9 X-ray flare reported by GOES on NOAA AR 10604 (located by the time at S19W29) between 03:48 - 04:04 UT with peak emission at 03:55 UT. 06:50 UT EN East Faint spray-like front that fades throughout C2. It is followed slightly to S at 07:27 UT by a very narrow ragged loop front.
