00:06 UT WN West Diffuse loop front surrounded by a very faint front Asymmetric develops as an asymmetric Full Halo CME. The C2 HALO occulting disk is completely surrounded by 00:54 UT (though the signatures are very faint on E). The event is first seen in C3 at 00:42 UT above the W Limb. By 02:42 UT the C3 occulting disk seems to be completely covered (as in C2, the halo is barely visible on E). GOES reported a C4.9 X-ray flare on NOAA AR 10734 (S03W24) on 2005/02/16 between 23:29 - 23:53 UT with peak emission at 23:38 UT. The flare occurs just after a B4.7 X-ray-flare on NOAA AR 10735 (S10W03) also at the end of previous day, between 23:03 - 23:19 UT with peak emission at 23:15 UT. EIT 195 running difference images show a relatively strong brightening on AR at 23:36 UT. An extremely faint intensity disturbance can be guessed afterward developing mainly toward NW of the AR. The event has therefore been determined as a faint asymmetric full halo CME, frontsided. 05:54 UT E Limb Extremely narrow loop-like feature developing slightly toward ENE. It fades throughout C2. 09:06 UT W Limb Faint and diffuse loop front. By 10:30 UT a small blob-like front becomes discernible on SW. They fade throughout C3. 09:30 UT S East Faint and ragged loop front along streamer that fades thtoughout C3. 18:06 UT W Limb Small blob-like front developing slightly toward WSW. Corresponding infalling material a little bit to N. 21:54 UT S Pole Diffuse jet-like front accompanied on SSW by a very faint and diffuse front that fades throughout C2. 23:30 UT W Limb Ragged loop front much brighter to S. It fades throughout C3. Note: Multiple B-class flares and one C2.3 X-ray flare on NOAA AR 10732 (around N15W90) since 20:56 UT.
Note: Couple of C-class X-ray flares from NOAA AR 10732 since the beginning of the day (around N15W90) until 01:30 UT. 04:30 UT S Pole Diffuse jet-like front.
