Solar activity increased to high levels. Region 95 (N07E65) produced an X1/Sf flare at 30/1329 UTC that had an associated Type II radio sweep with an estimated shock velocity of 457 km/s, a 780 sfu Tenflare, and significant discrete radio bursts. It appears to have fully rotated on to the visible disk and it appears to contain a beta-gamma magnetic structure. This region was also responsible for multiple C-class flares during the period. Region 87 (S08W33) continued to show steady decay in penumbral structure as the magnetic delta complex is no longer evident. New Region 96 (S14E75) was assigned today.

Solar activity is expected to be at moderate levels. Regions 87 and 95 are both capable of producing isolated major flare activity.

The geomagnetic field was at quiet to unsettled levels.
