Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1907 1907 1908 570 B. Proton Events: None. C. Geomagnetic Activity Summary: The geomagnetic field reached active levels early in the period due to the waning effects of a CME, but was at quiet to unsettled levels through the remainder of the period, due to the weak influence of a negative polarity CH HSS.
