Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field ranged from quiet to major storm levels. Geomagnetic storming occurred between 03/0000 - 0600 UTC after a period of sustained southward Bz. Solar wind speed showed a steady decline with initial values around 675 km/s to day-end values around 550 km/s. The total interplanetary magnetic field at ACE declined throughout the period, ending the day at about 5 nT. D. Stratwarm: Not Available E.
