Highlights of Solar and Geomagnetic Activity
12 - 18 January 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 mostly quiet levels during the period. However, brief unsettled to active periods occurred at high latitudes during 14 - 15 January. In addition, a 13 nT sudden impulse (SI) was detected at Boulder at 14/0121 UTC; likely associated with a faint, slow CME observed on 09 January. ACE solar wind measurements indicated minor changes during the period. Velocities ranged from 289 to 433 km/sec. A weak shock was observed
at the ACE spacecraft at 14/0015 UTC, in advance of the SI mentioned above, with minor changes detected in velocity and IMF.
Forecast of Solar and Geomagnetic Activity
21 January - 16 February 2009
Solar activity is expected to be at very low levels. No proton events are expected at synchronous 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 during 21 - 26 January. Activity is expected to increase to quiet to unsettled levels, with isolated active levels at high latitudes during 27 - 30 January due to a recurrent coronal hole high-speed stream (CH HSS).
Activity is expected to decrease to quiet levels during 31 January - 14 February. Activity is expected to increase to quiet to unsettled levels on 15 February with isolated active levels due to a recurrent CH HSS. Activity is expected to decrease to quiet levels on 16 February as the HSS subsides.
