The geomagnetic field has been quiet to minor storm, with severe storm conditions at high latitudes. An interplanetary shock passed the ACE spacecraft at 18/0005 UTC; subsequently the Boulder magnetometer registered a 50 nT sudden impulse at 18/0048 UTC. This shock was likely associated with the X14/2B on 15 April. Greater than 10 MeV and greater than 100 MeV proton events began at 18/0315 UTC and 18/0255 UTC respectively, most likely associated with the activity from old Region 9415 behind the west limb. The greater than 10 MeV protons reached a peak of 321 pfu at 18/1045 UTC, while the greater than 100 MeV reached 12 pfu at 18/0600 UTC. The Thule neutron monitor measured a ground level event between 18/0242 UTC and 18/0914 UTC; polar cap absorption (PCA) event began at 18/0425 UTC and remains in progress. Values for the greater than 2 MeV electrons at geosynchronous orbit were not reported due to sensor contamination by the proton event.
