Highlights of Solar and Geomagnetic Activity
04 - 10 February 2008
Solar activity was very low. No flares were detected. Region 982 (S09, L = 248, class/area Bxo/060 on 30 January) decayed to plage early in the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during 4 - 9 February.
The geomagnetic field was mostly quiet during 04 - 09 February. Activity increased to minor storm levels on 10 February with major to severe storm levels detected at high latitudes. ACE solar wind measurements indicated a solar sector boundary crossing on 08 February (negative (toward) to positive (away) polarity) associated with minor changes in velocity, proton density, and the interplanetary magnetic field (IMF). A co-rotating interaction region (CIR) was detected during 09 - 10 February, in advance of a recurrent coronal hole high-speed stream. The CIR was associated with increased proton densities (peak 27 p/cc at 10/0506 UTC) and significant changes in the IMF including increased Bt (peak 17 nT at 10/0600 UTC) and intermittent periods of southward Bz (minimum -15 nT at 10/1020 UTC). The high-speed stream commenced early on 10 February and reached a peak velocity of 742 km/sec near the close of the period.
Forecast of Solar and Geomagnetic Activity
13 February - 10 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 during
13 - 24 February and 29 February - 10 March.
The geomagnetic field is expected to be unsettled to active on 13 February due a recurrent coronal hole high-speed stream. Quiet to unsettled conditions are expected during 14 - 15 February as the high-speed stream gradually subsides. Mostly quiet conditions are
forecast for 16 - 27 February. Activity is expected to increase to active levels during 28 - 29 February due to another recurrent coronal hole high-speed stream. Quiet to unsettled levels are
expected during 01 - 07 March as the high-speed stream subsides. Activity is expected to increase to active levels during 08 - 09 March with minor to major storm periods possible at high latitudes due to a recurrent coronal hole high-speed stream. Unsettled conditions are expected on the last day of the period as the high-speed stream begins to subside.
