Solar activity was moderate due to a single M-class event during the period. Region 213 (N14E50) produced an impulsive M2/2n event, with associated tenflare and Type II/IV radio sweeps, at 04/2249 UTC. The region appears to be a relatively small sunspot group with minor magnetic complexity, near the somewhat larger Region 212 (N12E35) which remained quiescent during the period. Single C- and B-class x-ray enhancements were also observed without optical correlation later in the period, but otherwise the x-ray emissions from the sun have remained relatively flat. Two new regions were numbered today: 214 (N12W27) and 215 (S18E74). The latter appears to be a return of old Region 191 (S18, L=203) but limb proximity prevents detailed analysis.

Solar activity is expected to be predominantly low, with an increasing trend in chances for isolated moderate flare activity over the course of the next three days.

The geomagnetic field was quiet to unsettled. Flux levels for greater than 2 MeV electrons at geosynchronous orbit were observed to briefly exceed threshold for high values around the time of local satellite noon.

The geomagnetic field is expected to be quiet to unsettled through day two of the forecast period, with a trend toward more active conditions by day three, due to expected coronal hole effects. Greater than 2 MeV electron flux at geosynchronous orbit is expected to be below the high value threshold for the period.
