Solar activity was low. Region 9845 (N18W18) produced the largest flare of the period, a C4/Sf at 02/2016 UTC. Earlier, an impressive prominence erupted off the southeast limb, near S43E90, beginning at about 02/1345 UTC. This event was visible in SOHO/EIT and H-alpha imagery, and a subsequent CME was seen in LASCO imagery, though not appearing earth-directed. A slight x-ray enhancement accompanied this event, and persisted through the remainder of the period. New Region 9853 (S24E69) was numbered today.

Solar activity is expected to be predominantly low. A chance for isolated M-class activity exists for Region 9845.

The geomagnetic field was mostly quiet, with some isolated unsettled periods during 02/1500-2100 UTC.

The geomagnetic field is expected to be quiet to unsettled through day one. Onset of high speed stream effects from a large, positive-polarity coronal hole are expected to develop during day two, and persist for the remainder of the forecast period, with active conditions likely and isolated minor storm periods at higher latitudes possible.
