A partial Halo Coronal Mass Ejection (CME) predominantly directed to the south-east was detected in SOHO/LASCO-C2 data from around 12:48 UTC November 21. This originated from a filament eruption, visible in SDO AIA 304 over the east limb from 11:36 UTC November 21. This CME is therefore not expected to be Earth directed.

A halo Coronal Mass Ejection (CME) predominantly directed to the north-west was detected in SOHO/LASCO-C2 data from around 18:12 UTC November 21. This CME was associated with a region beyond the west limb and is therefore not expected to be Earth directed. However, an associated proton event was detected at Earth. The greater than 10 MeV GOES proton flux increased above the 10 pfu from 19:25 UTC November 21 and reached a maximum value of 125pfu at 03:30 UTC November 22. The greater than 10 MeV GOES proton is currently around 75 pfu and is expected to remain elevated for the next days, with further increases possible in response to further high energy flaring activity from the same region beyond the west limb.
