Two partial halo coronal mass ejections (CMEs) were observed in LASCO/C2 coronagraph data in the early UTC afternoon on July 14th, a north-eastward and south-westward one. Both are estimated to miss Earth with no expect impact. Another partial halo CME was observed in LASCO/C2 coronagraph imagery at 19:10 UTC. The CME is associated to an on disc filament eruption related to a C8.8-flare, peak time 18:44 UTC on July 14th, from plage region NOAA AR 3370. The CME is currently being analysed, but overlapping with previous partial halo CME from the east limb and lack of STEREO data for this interval makes analysis more difficult. Based on the source location and SDO/AIA 304 images the eruption is likely to have an Earth-directed component and impact on Earth. Expected arrival times and foreseen geomagnetic impact will be presented later.
