Proton Events: The greater than 10 MeV proton flux saw a slight enhancement (below S1-Minor levels) and remained slightly enhanced at the end of the reporting period. C. Geomagnetic Activity Summary: The geomagnetic field is expected to be quiet to unsettled for day one (29 Dec) and into the first part of day two (30 Dec). Mid to late on day two should see the arrival of the 28 Dec CME bringing active to major storming with it. Day three (31 Dec) should see minor storm levels early in the day before waning CME effects return the Earths magnetic field to unsettled to active levels. D. Stratwarm: Not Available E.
