Highlights of Solar and Geomagnetic Activity
12 - 18 November 2007
Solar activity was very low. Only minor flare activity was observed.
New Region 974 (N13, L=201, class/area, Dao/040 on 17 November) formed on the disk on the 16th, but decayed to plage by 18 November.
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 13 November. Interplanetary Magnetic Field changes associated with
the CIR included increased Bt (peak 15.4 nT at 13/0156 UTC) and variable Bz (range +9.3 nT to -11.8 nT). Velocities gradually increased to a peak of about 690 km/sec at 14/1051 UTC, then gradually decreased during the remainder of the period. ACE proton densities associated with the CIR increased to a peak of 23.1 p/cc at 13/0224 UTC.
Forecast of Solar and Geomagnetic Activity
21 November - 17 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 21 November - 01 December and again on 16 December.
Activity is expected to be at unsettled to minor storm levels during 21 - 22 November as a recurrent coronal hole high-speed stream 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 mostly quiet levels for the balance of the period.
