Highlights of Solar and Geomagnetic Activity
23 - 29 November 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 initially quiet. An increase to quiet to unsettled with some isolated high latitude active periods (as well as a single minor storm period at high latitudes) occurred on 25-26 November. Activity returned to quiet levels for the remainder of the period from 27-29 November. Solar wind observations from the ACE spacecraft showed the onset of a co-rotating interaction region mid-day on 24 November, which was followed by the onset of a high
speed stream. The high speed stream continued through 25 November with peak velocities around 470 km/s, and slowly declined on 26 November. The high speed stream was associated with the extension of the southern polar coronal hole as observed in solar EUV imagery.
Forecast of Solar and Geomagnetic Activity
02 - 28 December 2009
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 2-4 December. An increase to quiet to unsettled levels is expected on 5-6 December due to a recurrent high speed stream. Activity levels are expected to be predominantly quiet for 7-17 December, followed by another
increase to quiet to unsettled on 18 December, again due to a recurrent high speed stream. Quiet levels are expected to predominate for the remainder of the outlook period.
