Solar activity was at low levels. Region 177 (N16W09) produced the two largest flares during the period, a C7.5/Sf event occurred at 05/1257 UTC and a slightly smaller C6.4/Sn flare maximum was recorded at 05/1610 UTC. Magnetic analysis indicates slight growth in complexity while the average white-light area is now at 390 millionths with 17 spots. Region 180 (S10E17) only managed to produce minor C-class flares today. Even so, the magnetic structure to this region has shown significant growth during the period with the dominant lead spot exhibiting a distinct delta complex. New Region 186 (N20E02) was numbered today.

Solar activity is expected to be at low to moderate levels. Both Regions 177 and 180 have M-class flare potential.

The geomagnetic field was at unsettled to active levels. The Bz component of the interplanetary magnetic field remained mostly southward today. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the past 24 hours.

The geomagnetic field is expected to be at unsettled to active levels into the first day of the period. The elevated solar wind speeds in response to a geoeffective high speed coronal hole stream should begin to diminish by the end of day one, returning to predominantly quiet to unsettled conditions on days two and three. The greater than 2 MeV electron flux at geosynchronous orbit should reach moderate to high levels again tomorrow, 06 November.
