Highlights of Solar and Geomagnetic Activity
27 October - 02 November 2008
Solar activity was very low through the period. New-cycle polarity Region 1007 (N35, L = 250, class/area Bxi/060 on 02 November) produced isolated B-class flares on 02 November.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit increased to high levels during 30 October - 02 November.
Geomagnetic field activity was at quiet levels during 27 - 28 October. Activity increased to active levels during 29 - 30 October. Activity decreased to quiet to unsettled levels on 31 October.
Activity decreased to quiet levels during the remainder of the period. ACE solar wind measurements indicated a recurrent coronal hole high-speed stream (CH HSS) commenced on 28 October. Solar wind velocities increased from a low of 287 km/sec at 28/0056 UTC to a
high of 741 km/sec at 29/1648 UTC. Velocities began to gradually decrease on 31 October as the HSS subsided. Interplanetary magnetic field changes associated with the onset of the CH HSS included increased Bt (peak 14 nT at 28/1841 UTC) and intermittent periods of
southward Bz (minimum -10 nT at 29/0447 UTC).
Forecast of Solar and Geomagnetic Activity
05 November - 01 December 2008
Solar activity is expected to be at very low levels. However, there will be a chance for low activity (isolated low-level C-class flares) during 20 November - 01 December with the return of (old) Region 1007 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 05 - 15 November and 26 November - 01 December.
Geomagnetic field activity is expected to be at quiet levels on 05 November. Activity is expected to increase to unsettled levels on 06 November. A further increase to active to major storm levels is expected during 07 - 08 November due to a recurrent coronal hole high-speed stream (CH HSS). Activity is expected to decrease to unsettled levels on 09 November as the HSS subsides. Quiet conditions are expected during 10 - 24 November. Field activity is expected to increase to unsettled to active levels during 25 - 27 November due to a recurrent CH HSS. Activity is expected to decrease to quiet levels during 28 November - 01 December as the HSS
subsides.
