Solar activity was at low levels today. Flare production was limited to C-class activity throughout the period. Region 508 (S19W44) produced the largest flare of the day, a C3 x-ray flare that occurred at 28/0913Z. This region underwent a slight growth in magnetic complexity and areal coverage in the spot group over the past 24 hours. Region 507 (N07W56) produced a single event, a C1 x-ray flare that occurred at 28/0555Z. No significant changes were observed in this group during the period. Region 510 (S23E11) produced a C1 x-ray flare at 27/2210Z. This region has nearly doubled in penumbral coverage since yesterday while the magnetic field appears to remain a simply structured complex. Regions 515 (S02E68) and 516 (S17E70) were newly numbered today.

Solar activity is expected to be at low to moderate levels.

The geomagnetic field was at quiet to unsettled levels. The greater than 2 MeV electron fluxes at geosynchronous orbit reached high levels today.

The geomagnetic field is expected to be at predominantly quiet to unsettled levels. Isolated active conditions are possible throughout the period, mainly at higher latitudes. A transequatorial coronal hole is expected to become geoeffective by 30 Nov, enhancing the potential for isolated active periods.
