Solar activity was low. Though several regions currently reside on the visible disk, none show significant potential for greater than C-class flare activity. Two new regions; 450 (S18E66) and 451 (S10W65) were numbered today.

Solar activity is expected to be low. Regions 450, 449, and 445 have a fair chance of producing C-class flare activity. No other activity is expected.

The geomagnetic field has been at quiet to minor storm levels. Two periods of minor storming occurred one at 1200 and another at 1700 UTC. The solar wind speeds continue to be elevated above 450 km/s, reaching over 600 km/s toward the end of the period. This combined with a sustained southward interplanetary magnetic field polarity have kept the geomagnetic field elevated. The greater than 2 MeV flux at geosynchronous orbit reached high levels today.

The geomagnetic field is expected to be at quiet to unsettled levels for the next two days. By late on day three, geomagnetic activity should increase to unsettled to minor storm levels due to a co-rotating interaction region associated with a coronal hole.
