A halo coronal mass ejection (CME) was first observed on the SOHO/LASCO C2 images around 16:28 UTC on Jul 21. This CME was associated with a M1.0 flare from NOAA AR 3757 (N15 E20) and an eruption of a very twisted filament with the main propagation direction towards North. The first estimation shows projected speed of the CME to be about 730 km/s which brings expected arrival time at Earth to be around 05:00 UTC on Jul 24.
