There were two partial halo CMEs observed in the latest coronagraph data. The first one was seen by LASCO C2 at 05:08 UTC on 14 March, with an angular width of about 140 degrees, directed towards the east. The second one, observed by LASCO C2 at 02:10 on 15 March with an angular width of 150 degrees and directed towards the west (related to flaring activity from NOAA AR 3599 over the west limb). Both of these eruptions occurred close to the limb but are mostly backsided, the corresponding ICMEs are not expected to arrive to the Earth. The second one was associated with an increase in the 10 MeV proton flux at Earth, at the moment of writing the flux is still below the 10 pfu threshold.
