Solar activity was low. The highlight of the period was a very long duration, C2 X-ray event that began around 0915Z, peaked at 1257Z, and ended at 1625Z. This event was associated with an impressive coronal mass ejection off the SE limb, near Region 19 (S18E61). This event followed another CME associated with a filament eruption from near S40W10. Neither CME appears earthbound. Region 19 is a moderately complex spot group with a white light area of over 400 millionths. Region 17 (S19W23) has also increased in size and appears to have developed some magnetic complexity.

Solar activity is expected to continue at low levels. There is a chance for an isolated M-class flare from Regions 17 and 19.

The geomagnetical field was quiet to unsettled with isolated high latitude active periods.

The geomagnetic field is expected to continue at quiet to unsettled levels with isolated active periods during local nighttime hours.
