SOHO Telemetry Submode changed back to Submode 5 on 2004/12/01 @ ~ 19:00 UT. EIT 195 CME watch at half resolution (512x512) since then. After the EIT Shutterles Campaign and while in Submode 6, EIT 195 CME watch at full resolution (1024x1024). SOHO Telemetry Submode changed to Submode 6 at 14:00 UT on 2004/11/30 (EIT Shutterless Campaign between 17:00 - 19:40 UT). It will be back to Submode 5 on 2004/12/01 at 19:00 UT. SOHO is in Telemetry Submode 5 since 2004/11/08 @ 22:15 UT. While in Submode 5, half resolution EIT 195 CME watch (512x512).
W Infalling material and some faint small blobs coming out in the Western hemisphere all along the day. Otherwise, mostly quiet Sun until close to the end of the day when a Full Halo Event occurred. 05:26 UT SS East Faint elongated and thin loop front followed at 06:50 UT a little bit to N by a faint jet-like front. 20:26 UT NW - SE Brightenings above the NW and SE Limbs. The event HALO develops as a Full Halo CME by 21:26 UT (C2 occulting disk fully surrounded by that time). LASCO Data Gap afterwards (See Notes below). GOES reported a long duration X-ray event (C2.5) originating from NOAA AR 10709 (N01W07) between 19:34 - 20:44 UT with peak emission at 19:59 UT, associated to the event seen on LASCO. EIT 195 images show a brightening on the AR mentioned above starting at 19:36 UT. Post flare loops afterward. Relatively large dimming region to E and W of the AR. For completeness, also note that a second X-ray flare (C1.1) was reported, this time originating on NOAA AR 10710 (S09E49) on 2004/12/09 between 00:09 - 00:15 UT with peak emission at 00:10 UT. Last image analyzed: 21:26 UT (C2 time). LASCO Data Gap afterward. Last EIT image before Data Gap at 21:36 UT. - Notes: . SOHO Telemetry lost at 21:58 UT. . Telemetry recovered in low rate at 22:12 UT. Spacecraft in ESR (Emergency Sun Reacquisition Mode) when telemetry recovered.
- Notes (continue): . As part of nominal recovery SOHO entered CRP mode (Coarse Roll Pointing) at 04:44 UT. . Since SOHO is still in low telemetry rate until some time today, recovery will be performed somewhen during the day.
