Highlights of Solar and Geomagnetic Activity
03 - 09 November 2008
Solar activity was very low to low through the period. New-cycle polarity Region 1007 (N35, L = 252, class/area Dso/080 on 03 November) produced isolated low-level C-class flares on 03 and 04 November.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit increased to high levels on 06 and 09 November.
Geomagnetic field activity was at quiet levels during 03 - 06 November. Activity increased to unsettled to active levels from early on 07 November to midday on 09 November, During this same period, high latitudes observed active to minor storm levels with an isolated major storm period midday on 08 November. Activity decreased to quiet levels midday on 9 November through the end of the summary period. ACE solar wind measurements indicated a
recurrent coronal hole high-speed stream (CH HSS) commenced on 07 November. Solar wind velocities increased from a low of 279 km/sec at 06/1704 UTC to a high of 601 km/sec at 08/2003 UTC. Velocities began to gradually decrease early on 09 November as the HSS
subsided. Interplanetary magnetic field changes associated with the onset of the CH HSS included increased Bt (peak 12 nT at 07/2007 UTC) and intermittent periods of southward Bz (minimum -10 nT at 07/2057 UTC).
Forecast of Solar and Geomagnetic Activity
12 November - 08 December 2008
Solar activity is expected to be at very low levels. However, there will be a slight chance for low activity (isolated low-level C-class flares) during 20 November - 03 December with the return of (old) Region 1007 (N35, L=252) to the visible disk.
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 12 - 15 November, 26 November - 03 December, and again during 06 - 08 December.
Geomagnetic field activity is expected to be at quiet levels during 12 - 23 November. Activity is expected to increase to mostly unsettled levels during 24 - 28 November due to a recurrent CH HSS. Quiet levels are expected during 29 November - 02 December followed by an increase to unsettled to isolated active levels during 03 - 06 December due to another recurrent CH HSS. Activity is expected to be mostly quiet during 07 - 08 December as the HSS subsides.
