Highlights of Solar and Geomagnetic Activity
19 - 25 January 2009
Solar activity was very low. No significant flare activity was observed. Region 1011 (S12, L305, class/area Bxo/010 on 20 January) formed on the disk on 19 January and decayed to spotless plage by 20 January.
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 mostly quiet levels during the period. A single active period was observed at all latitudes early on 19 January. This activity was due to a recurrent coronal hole. A 12 nT sudden impulse was detected at Boulder at 25/2225 UTC. During the early part of the summary period, ACE solar wind velocities ranged from a high of 501 km/sec at 19/1931 UTC to a low of 265 km/sec at 25/1056 UTC. The Bz component of the IMF ranged primarily
between -4 nT to +3 nT. At the beginning of the summary period, the Bz component varied between -10 nT to +8 nT. At the end of the period, the Bz component ranged between -7nT to +4 nT. The Bt varied from 0-13 nT during the entire summary period.
Forecast of Solar and Geomagnetic Activity
28 January - 23 February 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 to unsettled levels on 28 January. Activity is expected to decrease to quiet levels during 29 January - 14 February. Activity is expected to increase to quiet to unsettled levels on 15 February, with isolated active levels 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. Activity is expected to decrease to mostly quiet levels on 23 February.
