Highlights of Solar and Geomagnetic Activity
30 November - 06 December 2009
Solar activity was very low. No flares occurred during the period. The solar disk was spotless during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal background levels during the period.
The geomagnetic field was quiet throughout the period. Solar wind observations from the ACE spacecraft showed the onset of a co-rotating interaction region early on 06 December, which was followed by the onset of a very weak high speed stream. The high speed stream velocities averaged around 380 km/s, and slowly declined thereafter. The high speed stream was associated with an isolated northern recurrent coronal hole as observed in solar EUV
imagery.
Forecast of Solar and Geomagnetic Activity
09 December 2009 - 04 January 2010
Solar activity is expected to be predominantly very low with just a slight chance for brief periods of low. No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal background levels through the period.
The geomagnetic field is expected to be quiet for 9-17 December. An increase to quiet to unsettled levels is expected on 18 December due to a recurrent high speed stream. Quiet levels are expected to predominate for the remainder of the outlook period.
