Highlights of Solar and Geomagnetic Activity
05 - 11 November 2007

Solar activity was very low. No flares were detected. The visible disk was spotless during most of the period. Region 973 (S11, L = 019, class/area Axx/010 on 07 November) was numbered on 07 November, but quickly decayed to plage.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels throughout the period.

The geomagnetic field was quiet during most of the period. However, ACE solar wind measurements indicated a recurrent co-rotating interaction region (CIR) and coronal hole wind stream commenced on 08 November. Interplanetary Magnetic Field changes associated with the CIR included increased Bt (peak 10.8 nT at 09/1557 UTC) and variable Bz (range 6.0 nT to -7.0 nT). Velocities gradually increased to a peak of 458.5 km/sec at 10/1438 UTC, then a gradually decreased during the remainder of the period. Proton densities associated with the CIR increased to a peak of 10.2 p/cc at 09/1408 UTC.

Forecast of Solar and Geomagnetic Activity
14 November - 10 December 2007

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 November - 01 December.
Activity is expected to be at unsettled to active levels during 14 - 15 November due to recurrent coronal hole effects. Quiet to unsettled conditions are expected during 16 - 20 November. Activity is expected to increase to unsettled to minor storm levels during 21 - 22 November as another recurrent coronal hole disturbs the field. Activity is expected to decrease to quiet to unsettled levels during 23 - 26 November as coronal hole effects subside. Activity is expected to decrease to quiet levels for the balance of the period.
