Solar activity was low during the past 24 hours. Today's activity consisted of occasional low-level C-class subflares. The majority of these were from Region 132 (N20W53), which continues to be the largest group on the disk and also the most complex with a beta-gamma magnetic configuration. This group has decreased in area during the past 24 hours. Region 134 (N11E50) showed moderate growth and managed to produce a subflare. Region 130 (N06W04) also showed growth.

Solar activity is expected to be predominantly low for the next three days. There is a slight chance for an isolated M-class event from Region 132 or Region 134.

The geomagnetic field was mostly quiet during the past 24 hours.

The geomagnetic field is expected to be mostly quiet for the next three days. There is a possibility for an increase to unsettled to active late on the third day as a positive polarity coronal hole will be rotating into a geoeffective position at that time.
