Highlights of Solar and Geomagnetic Activity
25 February - 02 March 2008
Solar activity was very low with no flares detected.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on all days but 28 February.
The geomagnetic field was at quiet to unsettled levels during 25 - 27 February. By early on 28 February, activity increased to unsettled to active levels with isolated minor storm periods observed at middle latitudes, while minor to major storm periods were observed at high latitudes. This activity persisted through midday on 01 March and was due to a recurrent coronal hole high speed stream. ACE solar wind measurements peaked at 837 km/s at 01/0603 UTC) while density peaked at 24 p/cc at 27/1541 UTC. Significant changes in the IMF were observed from late on 27 February through midday on 28 February including increased Bt (peak 11 nT at 27/1651 UTC) and intermittent periods of southward Bz (minimum -11 nT at 27/1651 UTC). The high-speed stream began decaying early on 02 March and ended the summary period with velocities near 575 km/s.
Forecast of Solar and Geomagnetic Activity05 - 31 March 2008
Solar activity is expected to be very low.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on all days of the forecast period except 26 March.
The geomagnetic field is expected to be mostly quiet to unsettled on 05 - 07 March. Activity is expected to increase to unsettled to active levels during 08 - 13 March with minor to major storm periods possible at high latitudes due to a recurrent coronal hole high-speed stream. Quiet to unsettled conditions are expected during 14 - 24 March as the high-speed stream subsides. Activity is expected to increase to unsettled to active levels during 25 - 28 March with minor to major storm periods possible at high latitudes due to a recurrent coronal hole high-speed stream. Quiet to unsettled conditions are expected during 29 - 31 March as the
high-speed stream subsides.
