Highlights of Solar and Geomagnetic Activity
26 November - 02 December 2007
Solar activity was very low. Region 977 (S05, L = 290, class/area Bxo/020 on 02 December) produced several subflares during 01 - 02 December. Region 977 emerged on 01 December and gradually developed during the remainder of the period, but remained simply structured.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels throughout the period.
The geomagnetic field was quiet to unsettled during 26 - 27 November. Activity decreased to quiet levels for the rest of the period. ACE solar wind measurements indicated a gradual decrease in velocities during 26 - 30 November as a recurrent coronal hole high-speed
stream subsided. Peak solar wind velocity was 655 km/sec at 26/0517 UTC. Velocities decreased to as low as 310 km/sec by the end of the period. Minor IMF variations occurred during the period with Bt in the 01 to 06 nT range and Bz in the +5 to -4 nT range.
Forecast of Solar and Geomagnetic Activity
05 - 31 December 2007
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 19 - 31 December.
The geomagnetic field is expected to be at mostly quiet levels during 05 - 16 December. Activity is expected to increase to unsettled to active levels during 17 - 19 December due to recurrent coronal hole effects. Minor storm levels are also expected on 17 December.
Activity is expected to decrease to quiet to unsettled levels during 20 - 23 December as coronal hole effects subside. Activity is expected to decrease to quiet levels for the balance of the period
