Highlights of Solar and Geomagnetic Activity
02 - 08 February 2009
Solar activity was very low. No flares were observed. The visible
disk was spotless.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
normal levels.
Geomagnetic field activity was at quiet levels on 02 February. A sudden impulse of 10 nT was observed at the Boulder magnetometer at 2014 UTC on 03 February, following a discontinuity in the solar wind signature observed at the ACE satellite. Quiet to minor storm conditions, with major storm levels at high latitudes, were observed from late on 03 February to early on 04 February. During this period, solar wind signatures from the ACE satellite were consistent
with a possible CME. Activity decreased to quiet conditions for the rest of the period. During the summary period, ACE solar wind velocities ranged from a high of 405 km/s at 04/0050 UTC to a low of 298 km/s at 06/1750 UTC. The Bz component of the IMF ranged primarily between -3.5 nT and +3.8nT. However, between 03/1912 UTC and 05/0155 UTC, Bz varied between -10 nT and +10 nT.
Forecast of Solar and Geomagnetic Activity
11 February - 09 March 2009
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 be at normal levels.
The geomagnetic field is expected to be at quiet levels 11-14 February. Activity is expected to increase to quiet to unsettled levels, with isolated active conditions, on 15 February due to a
recurrent coronal hole high-speed stream (CH HSS). Activity is expected to decrease to quiet levels during 16-21 February as the HSS subsides. Activity is expected to increase to quiet to unsettled levels, with isolated active levels, on 22 February due to another CH HSS. Isolated minor to major storm conditions are possible at high latitudes during this period. Activity is expected to decrease to mostly quiet levels from 23 February - 09 March.
