Comet C/2004 F4 (Bradfield) is now visible in the C3 field of view. A special observing campaign is in progress (2004/04/16 - 2004/04/19). Synoptic observations will be modified during this period. 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).
N East Gusty outflow all along the day. 03:26 UT S West Spray-like front. It fades throughout C3. 08:06 UT S West Bright narrow ragged front along streamer, slightly to S of previous event. It fades throughout C3. 08:06 UT N West Loop front that quickly fades. At 08:26 UT a bright ragged front appears at the PA of the northern leg of the loop, moving much faster. It also fades througout C3. 11:06 UT N East Very ragged front in the gusty outflow, preceded at ~07:27 UT by an elongated ragged front barely discernible from the gusty outflow. 17:26 UT W Limb Ragged front and apparently twisted trailing structure developing slightly toward NE. 18:06 UT N Pole Very faint diffuse loop front that quickly fades. 20:06 UT E Limb Fairly faint and diffuse loop front, that fades close to the inner edge of C3. A fainter one developing toward SE can be distinguished since 20:50 UT. It fades by the end of C2 FOV. 21:18 UT Comet Bradfield (C/2004 F4) first appears in C3 FOV, coming in from S (center bottom of the image).
05:42 - 11:42 UT Temporary DSN Data Gap.
