04:30 UT E Limb Elongated and diffuse faint loop-like structure. It is followed at 06:54 and 08:06 UT by a couple of similar fronts, all of them developing slightly toward ENE. They all fade very close to the inner edge of C3. 06:54 UT S West System of faint and diffuse expanding loop fronts. New loop fronts continuously develop all along the day. They all fade throughout C3. 14:00 - 16:40 UT EIT Shutterless Run in 304 A. Only about one C2 image/hour during the run.
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 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. 09:30 UT S East Faint and ragged loop front along streamer.
