Solar activity increased to moderate levels. Newly assigned Region 269 (S09E76) produced the largest flare during the period, an M1.9 x-ray event with associated loops occurred at 21/1526 UTC (no optical flare reported due to source center being just beyond the east limb). Based on NASA/LASCO imagery, this event produced a CME and it is doubtful that it will become geoeffective. Unable to determine how mature this region is at the time of this writing due to it's proximity to the east limb. Region 260 (N14W00) produced several C-class events throughout the interval and became slightly more magnetically complex during the past 24 hours. A C8.1 flare (correlated using SOHO/EIT imagery) occurred at 21/0228 UTC with an associated Type II radio sweep that had an estimated shock velocity of 700 km/sec. A C4.1/Sf event occurred at 21/0557 UTC that had an associated Type II radio sweep (shock velocity estimated at 700 km/sec) and a Tenflare. A 36 degree disappearing solar filament was observed at the beginning of the period that produced a CME which does not appear to be earth-directed. Region 268 (N12E23) was also numbered today.

Solar activity is expected to be at low levels. There is a chance of further M-class flare activity from region 269 pending further analysis as it rotates onto the visible disk.

The geomagnetic field was at quiet to active levels. A lingering southern coronal hole extension high speed stream is believed to be responsible for the elevated conditions. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.

The geomagnetic field is expected to be at predominantly unsettled levels for day one of the forecast period. By day two a transequatorial recurrent high speed stream coronal hole should become geoeffective producing active to minor storm conditions with isolated major storm periods possible.
