Solar activity was at low levels. Region 775 (N08E08) produced the largest event of the period which was a long duration C1.5 x-ray flare that occurred at 09/1334Z. This region underwent continued growth in sunspot area during the period with the eastern most delta structure from yesterday becoming detached from the dominant central spot. Although the delta structure to the south remains well intact. Region 776 (S06E20) produced a C1 x-ray flare that occurred at 09/1631Z and white light analysis showed minor growth in sunspot area. Region 772 (S18W71) appears to have continued to decay and was quiescent throughout the day. No new regions were numbered today.

Solar a activity is expected to be at low levels. Regions 775 and 776 may both be capable of producing an isolated low level M-class flare.

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

The geomagnetic field is expected to be at predominantly quiet to unsettled levels. Beginning late on 11 June, active conditions may occur due to the arrival of the faint partial halo CME that was observed yesterday.
