Highlights of Solar and Geomagnetic Activity
22 - 28 February 2010

Solar activity was at very low levels during the period. Region 1051 (N15, L=321, class/area Cso/040 on 26 February) produced the largest flare of the period, a B3.5 event at 24/0223 UTC. Region 1050 (S19, L=054, class/area Bxo/030 on 26 February) appeared on the disk on 23 February. Region 1051 (N17, L=322, class/area Cao/100 on 24 February) rotated on to the disk on 24 February.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal background levels.
Geomagnetic field activity was at predominantly quiet levels during the period. Real-time solar wind observations from the ACE satellite showed frequent weak fluctuations in the interplanetary magnetic field (IMF). The total field, Bt, varied primarily between 3 and 8
nT, while the southward component, Bz, varied from +8 and -6 nT. Solar wind speeds ranged between 283 km/s and 409 km/s.

Forecast of Solar and Geomagnetic Activity
03 - 29 March 2010

Solar activity is expected to be very low, with isolated periods of low levels, through the period.

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.

The geomagnetic field is expected to be predominantly quiet on 03-14 March. Quiet to isolated unsettled levels are expected on 15-16 March, due to a recurrent coronal hole. Activity is expected to return to quiet levels for the rest of the period.
