Highlights of Solar and Geomagnetic Activity
06 - 12 August 2007
Solar activity was very low to low. Region 966 (S06, L = 067,
class/area Dso/040 on 09 August) produced isolated B- and C-class flares on 06 August during a period of modest growth. Activity decreased to very low levels during the rest of the period with no flare activity observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during 07 - 12 August.
Geomagnetic field activity ranged from quiet to major storm levels during 06 - 07 August. Activity decreased to quiet to unsettled levels during 08 - 09 August. Activity increased to quiet to active levels during 10 - 12 August with minor storm periods observed at some high latitude stations. ACE solar wind data indicated the 06 - 07 August activity was due to a recurrent coronal hole high-speed stream. The high-speed stream commenced on 06 August and eventually reached a peak velocity of 661 km/sec at 07/1320 UTC. The density increase associated with the onset of the high-speed stream reached a peak of 28 p/cc at 06/1343 UTC while IMF Bt increased to a maximum of 19 nT at 06/3332 UTC and IMF Bz decreased to a minimum of -14 nT at 06/2308 UTC. ACE data indicated the 10 - 12 August disturbance was also due to a recurrent high-speed stream. This stream commenced on 10 August and reached a peak velocity of 593 km/sec at 10/2129 UTC. The density increase associated with the
onset of the high-speed stream reached a peak of 24 p/cc at 10/1248 UTC while IMF Bt increased to a maximum of 16 nT at 10/1345 UTC and IMF Bz decreased to a minimum of -11 nT at 10/1339 UTC.
Forecast of Solar and Geomagnetic Activity
15 August - 10 September 2007
Solar activity is expected to be at very low levels.
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 18 - 19 August and 28 August - 10 September.
The geomagnetic field is expected to be at quiet levels on 15 August. A recurrent coronal high-speed stream is expected to disturb the field during 16 - 17 August with unsettled to active levels expected. Quiet to unsettled conditions are expected during 18 - 24 August. Another recurrent high-speed stream is expected to disturb the field during 25 - 28 August with unsettled to active conditions expected. Activity is expected to decrease to quiet to unsettled
levels during 29 August - 02 September. Activity is expected to increase to unsettled to minor storm levels on 03 September due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to quiet to unsettled levels during 04 - 05 September.
Unsettled to active conditions are expected during 06 - 07 September as another recurrent high-speed stream disturbs the field. Activity is expected to decrease to quiet levels for the rest of the period.
