Highlights of Solar and Geomagnetic Activity
20 - 26 October 2008

Solar activity was very low. No flares were observed. The visible disk was spotless. No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels.

Geomagnetic field activity was at quiet levels during 20 - 21 October. Activity increased to unsettled levels on 22 October. Activity returned to quiet levels during 23 - 26 October. ACE solar wind measurements indicated minor variations during the period. Velocities ranged from approximately 290 - 450 km/sec. IMF Bt ranged from 01 - 10 nT. IMF Bz ranged from +09 to -07 nT. The increase to unsettled levels observed on 22 October was associated with increased velocities coupled with intermittent periods of southward IMF Bz.

Forecast of Solar and Geomagnetic Activity
29 October - 24 November 2008

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 30 October - 06 November and 08 - 15 November.

Geomagnetic field activity is expected to be at unsettled to active levels during 29 - 31 October with a chance for minor storm conditions on 30 October due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to mostly quiet levels during 01 - 06 November as the high-speed stream subsides. Activity is expected to increase to minor storm levels with a chance for major storm conditions on 07 November due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to unsettled to active levels during 08 - 09 November as the high-speed stream subsides. Activity is expected to decrease to quiet levels
during 10 - 23 November. Activity is expected to increase to unsettled levels on 24 November.
