* Telemetry KEYHOLE (SOHO will stay in TM Submode 5 during the Keyhole): 2005/06/05 - 2005/06/25: 26 m 2005/06/09 - 2005/06/20: 34 m * SOHO Maneuvers: 2005/06/17 - LASCO safes on 2005/06/16 (Thursday) at 15:30 UT. - Station keeping, Momentum management, and 180 deg Roll on 2005/06/17 (burns should be complete by ~15:55 UT). - LASCO recovery on 2005/06/18 (Saturday) at ~18:00 UT (or slightly earlier). * During the KEYHOLE, LASCO will be in synoptic improved program (12 min cadence C2, 30 min cadence C3), with little loss of telemetry throughout due to the advanced recorder setup. * 2005/05/06 - 2005/06/24: EIT Bakeout (==> No EIT CME Watch). EIT performed the long pre-bake calset (06/06 15:58-21:45 UT) and went to heaters on at 21:52 UT. EIT will be in bake till June 24 @ 10:00 UT and should resume imaging by (06/24) 20:00 UT.
00:00 - 09:12 UT Temporary Data Gap. 09:12 UT W Limb Bright, wide, and ragged loop front developing toward (HALO) West, already past the outer edge of the C2 FOV. Faint ragged extensions can be seen all above the N Pole, toward NE, and E. Though extremely faint, they can also be guessed above the S Pole. The event is caught so advanced in the C2 FOV because of a telemetry DSN data gap not filled yet (00:00 - 09:00 UT). The development of the event between 10:45 - 14:15 UT is also missed because of another telemetry DSN Data Gap not yet filled. The event was first seen in C3 at 09:18 UT already well above the W Limb. By 09:42 UT, the C3 occulting disk appears completely surrounded by the faint extensions. The last C3 image available of the event at the time of writing corresponds to 15:42 UT (afterward, telemetry DSN data gap not filled yet). The mean plane-of-sky speed of the LE at PA 267 was ~ 560 km/sec (based on a few C3 frames), showing a very slight acceleration. There are no EIT images available (EIT CCD bake out under way: 2005/06/06 21:52 - 2005/06/24 20:00 UT). GOES reported a C4.2 X-ray flare on NOAA AR 10775 (N10W47) between 06:54 - 07:56 UT with peak emission at 07:30 UT. The X-ray event on AR 10775 was preceded by an impulsive B5.4 X-ray flare on NOAA AR 10776 (S08W43), which occurred between 05:10 - 05:22 UT (peak emission at 05:16 UT). SXI-GOES 12 images show a relatively strong brightening of an (inverted) S-shaped feature on AR 10775 coincident with the reported X-ray flare. In summary, the event has therefore been determined as an asymmetric Full Halo CME, frontsided, associated to C-class X-ray activity on NOAA AR 10775. 10:36 - 14:24 UT Temporary Data Gap. 16:00 UT WN West Bright and ragged loop front. GOES reported a C7.4 X-ray flare on NOAA AR 10775 (N11W61) between 15:22 - 16:13 UT with peak emission at 15:48 UT. Due to the DSN Data Gap it is uncertain at the time of writing whether there was a partial or full halo associated to the X-ray event. 16:24 - 24:00 UT Temporary Data Gap.
02:12 - 10:24 UT Temporary DSN Data Gap. Time of the last C2 image under analysis: 10:48 UT
