Highlights of Solar and Geomagnetic Activity
06 - 12 October 2008
Solar activity was very low. No flares were observed. New-cycle polarity Region 1005 (N26, L = 119, class/area Cro/070 on 12 October) emerged on 11 October and was quiet and stable during the rest of the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during 06 - 10 October and 12 October.
Geomagnetic field activity was at mostly quiet levels during 06 - 10 October. Activity increased to as high as severe storm levels on 11 October. Activity decreased to active levels on 12 October with minor storm levels observed at high latitudes. ACE solar wind observations indicated a recurrent coronal hole high-speed stream (CH HSS) disturbed the field during 11 - 12 October. A co-rotating interaction region (CIR) was observed on 11 October in advance of the CH HSS. Solar wind changes associated with the CIR included a plasma density increase (peak 40 p/cc at 11/0648 UTC), increased IMF Bt (peak 16 nT at 11/0729 UTC), and periods of sustained southwar IMF Bz (minimum -14 nT at 11/0729 UTC). The velocity increase associated with CH HSS began early on 11 October and continued into 12 October with a peak velocity of 598 km/sec observed at 12/0432 UTC.
Forecast of Solar and Geomagnetic Activity
15 October - 10 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 15 October, 30 October - 06 November, and 08 - 10 November.
Geomagnetic field activity is expected to be at quiet levels during 15 - 27 October. Activity is expected to increase to active levels during 28 - 29 October due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to unsettled levels during 30 - 31 October as the high-speed stream subsides. Quiet conditions are expected during 01 - 06 November. Activity is expected to increase to minor to major storm levels on 07 November due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to active levels on 08 November and then decrease to unsettled levels during 09 - 10 November as the high-speed stream
subsides.
