Solar activity was at moderate levels today. Region 715 (N04E34) produced an M4/2n event that occurred at 30/2218Z along with an associated Tenflare (230 sfu), a Type IV spectral radio sweep, and a Type II spectral radio sweep with an estimated shock velocity of 1378 km/s. A related CME was observed on LASCO imagery which appears to have a slight Earth directed component. A more recent M1 x-ray flare occurred at 31/1445Z from this region, and due to insufficient data, it is uncertain whether this flare produced a CME. White light analysis has shown a decay in sunspot area over the period although a small delta magnetic structure can be seen in the southern most cluster of the penumbral spots. The remainder of the disk/limbs were quiescent today. A new region was numbered today as Region 717 (N07W56).

Solar activity is expected to be at low to moderate levels. Region 715 remains capable of producing M-class flare activity.

The geomagnetic field was at quiet to unsettled levels today.

The geomagnetic field is expected to be at quiet to unsettled levels through day one (1 Jan) of the period. A recurrent high speed coronal hole stream and the CME's that occurred yesterday in response to the M2/Sf event and the M4/2n event that occurred today should induce active to minor storm conditions on days two and three (2-3 Jan).
