A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
None
B. Proton Events
Proton fluxes for particles with energy > 10 MeV remained enhanced through the day but never exceeded the threshold to call an event. No significant increases have been observed following the X5 flare on 01/1910 UT.
C. Geomagnetic Activity Summary
Geomagnetic activity ranged from quiet to unsettled levels through the day.
D. Stratwarm
None
