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.
01:27 UT N West Elongated loop front and apparently twisted trailing material at ~ the PA of the leg on the NW Limb of the event reported to start at 21:26 UT on the previous day. Gusty outflow follows. 02:26 UT W Limb Fan-like front. 05:50 UT N Pole Elongated loop fronts. 12:50 - 19:27 UT Temporary Data Gap. 19:50 UT N West Slow development of system of loops along streamer.
05:06 - 11:00 UT Temporary Data Gap. 11:00 - 12:30 UT LASCO Data Gap due to ICAL01 (Intercalibration for EIT with CDS/SUMER).
