Highlights of Solar and Geomagnetic Activity
12 - 18 October 2009
Solar activity was very low. Isolated eruptive activity was observed in a plage region near S28W01 on 16 October. EIT wave activity and weak X-ray enhancements were associated with these eruptions. At around 17/1900 UTC, this plage region (near S28W14) produced a
two-ribbon flare. An associated faint, slow-moving (around 230 km/sec), Earth-directed partial halo CME was associated with this flare. 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 during the period. Geomagnetic field activity was at predominantly quiet levels during the period. Isolated unsettled periods were observed at mid-latitudes early on 16 October. The period began with ACE solar wind velocities at 419 km/s, before reaching a peak of 431 km/s at 12/0114 UTC, and decreasing to 292 km/s at 15/0345 UTC. A second velocity peak reached 439 km/s at 16/0015 UTC and ended the period around 291 km/s. Interplanetary magnetic field activity showed
intermittent periods of southward Bz during the period (minimum -5 nT at 15/1641 UTC). Bt reached a maximum of 11 nT at 15/1033 UTC. Density reached a maximum of 16 p/cc at 15/0912 UTC.
Forecast of Solar and Geomagnetic Activity
21 October - 16 November 2009
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 be at normal levels through the period.
Geomagnetic field activity is expected to be at predominantly quiet levels during 21-23 October. Quiet to unsettled levels, with isolated active to minor storm conditions at high latitudes, are expected on 24-25 October, due to a recurrent coronal hole high-speed stream. Predominantly quiet levels are expected for the rest of the period.
