Solar activity was moderate. Region 9468 (N05E25) produced an M1/1n flare at 24/1944Z. Minor centimetric bursts, a Type II radio sweep (620 km/s), and a CME also accompanied this flare. Region 9468 is a moderately complex group covering 150 millionths of white light area and produced frequent brightness fluctuations throughout the period. A pair of long duration C1 events were observed at 24/0706Z and 24/0901Z, and were likely associated with an impressive CME originating just behind the NE limb. A weak Type II sweep was observed at 24/1712Z, associated with a filament eruption and faint CME near the west limb. The largest region on the visible disk - Region 9463 remains stable in a simple beta configuration.

Solar activity is expected to be low to moderate. An isolated M-class event is possible from Regions 9463 and 9468.

The geomagnmetic field was quiet to unsettled. We have been under the influence of a high speed coronal hole stream for almost 40 hours, but the geomagnetic response so far has been weak.

The geomagnetic field is expected to be quiet to unsettled with isolated active periods through days one and two. Active to minor storm conditions are possible on day three in response to the CME at 24/1955Z.
