Solar activity has been low during the past 24 hours. Two noteworthy C-class events occurred during the day. The first was a C5 which started at 0105 UTC, reached maximum at 0203 UTC, and ended at 0443 UTC. There were no observations of corresponding disk activity, but there was a CME just behind the Northwest limb of the Sun that could be reasonably associated with the event. The other was a C6 with start-max-end times of 1448-1519-1547 UTC: newly assigned Region 9454 (N15E74) was seen to brighten in H-alpha during the event, and a CME became visible on the East limb in C2 observations at 1530 UTC. A type II sweep was also associated with this event. New Region 9454 is now the largest sunspot group on the disk with an area of 300 millionths in an Eao-Beta configuration.

Solar activity is expected to be mostly low, but there is a chance for an isolated M-class event from Region 9454.

The geomagnetic field ranged from quiet to minor storm levels. An initially active geomagnetic field reached minor storm levels between 0000-0900 UTC. Conditions declined thereafter and were quiet to unsettled during the last nine hours of the day.

The geomagnetic field is expected to be mostly unsettled during the next three days.
