Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0234 0234 0235 350 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to minor storm levels. A very weak signature from the NASA/ACE data indicate a transient may have passed around 28/1200Z although the elevated geomagnetic conditions are believed to be from a recurrent coronal hole. The greater than 2 MeV electron fluxes at geosynchronous orbit have again reached high levels. D. Stratwarm: None E.
