Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1954 1954 1954 150 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field activity was at quiet to minor storm levels. An isolated period of minor storm conditions occurred at 02/0600 - 0900 UTC. This was preceded with a sudden impulse at the Boulder magnetometer of 45 nT at 02/0558 UTC. This transient is presumed to be related to M3 x-ray flare that occurred in old Region 9787 at 31/1444 UTC. The optical correlation for this flare was attained using SOHO/EIT imagery, as this region had rotated beyond the west limb. D. Stratwarm: None E.
