A proton event started around 0h UT on May 29, and the greater than 10 MeV proton flux reached a maximum of about 16 pfu around 03:20 UT. Proton flux levels have gone below the 10 pfu threshold and are decreasing further.
This event is associated with a C9.4 flare produced by beta-gamma region NOAA 2824 which peaked at 23:13 UT on May 28, and with a CME towards the West first observed in LASCO C2 imagery at 23:12 UT. Pending further investigation of CME speed and properties, a preliminary speed estimate of 2087 km/s was obtained by a Type II radio burst.
The proton event is finished, but there is a chance for further proton events in the next 48 hours.
