Solar activity was at low levels today. Region 687 (N10E52) produced multiple C-class flares during the period, the largest was a C9.9 x-ray flare that occurred at 21/1948Z. At 21/0040Z this region produced a C7/Sf flare with an associated CME that was observed in LASCO. The CME does not appear to be Earth-directed. Close scrutiny of available data indicates that the penumbral area of Region 687 is a single polarity structure yielding a CSO beta-gamma sunspot classification. Region 682 (S13W46) produced two C-class flares during the period, a C1/Sf that occurred at 21/1442Z and a C4/Sf event occurring at 21/1522Z. Although the overall sunspot count went down the sunspot distribution of intermediate spots matured during the period which accounts for the compact classification. Region 689 (N12E74) seen on the solar east limb was numbered today.

Solar activity is expected to be at low to moderate levels. Region 682 and 687 are both capable of producing M-class flare activity.

The geomagnetic field was at quiet to unsettled levels.

The geomagnetic field is expected to be at quiet to unsettled levels throughout the period.
