PRESTO FROM SIDC - RWC BELGIUM Thu May 17 2012, 0530 UT

NOAA AR 1476 released an M5.1 flare peaking at 01:47 UT, as it rotated over the west limb. The flare produced an ongoing proton event with 100 MeV protons exceeding the threshold of 1 pfu (and 10 MeV protons already above 100 pfu). An associated CME was observed, travelling towards the west, it's not expected to arrive to Earth (although we may see the shock). Also type II radio bursts were detected.
