Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1936 1937 1937 100 2105 2105 2105 150 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to active. Solar wind speed continues to show a steady decline as the large southern coronal hole rotates out of a geoeffective position. Occasional periods of southward Bz account for the active levels. D. Stratwarm: None E.
