Solar activity reached moderate levels with an M1.5/1N flare on July 8 from Region 4482.

There are currently five numbered regions on the visible disk. Region 4482 demonstrated continued growth and developed a delta spot within its trailing spot group. Region 4485 displayed new flux emergence. Regions 4486 and 4487 were newly numbered during the period. Region 4481 was stable and remained an unremarkable unipolar group.

No Earth-directed CMEs were observed in available coronagraph imagery.

Solar activity is expected to remain at low levels through July 11, with a high chance for M-class (R1-R2/minor-moderate) flares and a slight chance for X-class (R3/strong and greater) events. This flare probability is almost entirely due to the complexity and potential of Region 4482.

Solar wind parameters reflected near ambient background conditions. Solar wind speeds were generally near 400 km/s. The phi angle was predominantly in the positive sector.
