Solar activity was at low levels. Region 198 (S18W12) produced the largest flare of the period, a C3.4/Sf flare occurring at 22/1542 UTC. Region has shown decay this period as penumbral coverage has decreased and gamma portion of the magnetic field has become less discernable, although it is still intact. Region 201 (S16W22) showed some growth today adding several umbra to group's total spot count. No new spot groups were numbered today.

Solar activity is expected to be at low levels. Region 198 has the potential to produce M-class flare activity.

The geomagnetic field was at unsettled to minor storm levels. The transequatorial coronal hole in the western solar hemisphere continues to elevate the high speed solar wind (today's approximate average speed of 625 km/s). The greater than 2 MeV electron flux at geosychronous orbit reached high levels today.

The geomagnetic field is expected to be at quiet to active levels. Isolated minor storm conditions (mostly at high latitudes) are possible through day one as the magnetosphere continues to be under the influence of the high speed solar wind. Days two and three should return to quiet to unsettled conditions as the high speed stream wanes. The greater the 2 MeV electron flux at GOES should reach daily moderate to high levels throughout the forecast period.
