Highlights of Solar and Geomagnetic Activity
01 - 07 October 2007
Solar activity was very low. A single B-class flare occurred on 05
October.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels throughout the period.
The geomagnetic field was at quiet to unsettled levels during 01 - 02 October. Activity increased to unsettled to active levels during 03 - 04 October. Activity decreased to quiet to unsettled levels on 05 October. Activity decreased to quiet levels during the remainder of the period. ACE solar wind data indicated a recurrent coronal hole high-speed stream (HSS) was in progress at the start of the period (peak velocity 572.6 km/sec at 01/0152 UTC), but was gradually decreasing. Velocities continued to decrease through 02 October and eventually reached a minimum of 396.9 km/sec at 02/1959 UTC. Another recurrent coronal hole HSS began on 02 October and ended near the close of the period. The co-rotating interaction region (CIR) that preceded the HSS began late on 02 October and was associated with a gradual increase in velocities (peak 611.1 km/sec at 03/1555 UTC), a minor density increase (peak 8.6 p/cc at 02/2108 UTC); and a period of enhanced IMF Bt and Bz variability. CIR-related IMF changes included a period of increased Bt (peak 8.7 nT at 03/0130 UTC) and Bz fluctuations in the + 7.6 nT to - 6.7 nT range. The HSS began to subside on 04 October and velocities gradually decreased during the remainder of the period.
Forecast of Solar and Geomagnetic Activity
10 October - 05 November 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 on 10 October and again during 21 October - 05 November.
Geomagnetic activity is expected to be at quiet levels during through 16 October. An increase to quiet to unsettled levels is expected during 17 - 19 October. A further increase to unsettled to active levels is forecast for 20 October as a recurrent coronal hole high-speed stream affects the field. Activity is expected to decrease to quiet to unsettled levels during 21 - 24 October as the high-speed stream subsides. Activity is expected to increase to unsettled to minor storm levels during 25 - 26 October due to another recurrent coronal hole high-speed stream. Activity is
expected to decrease to quiet to unsettled levels during the rest of the period.
