Solar activity was low. Today's largest event was a C4/Sf at 0456 UTC from Region 787 (S10W48). Region 787 is a small, simple, D-type group. Two additional, low level C-class events were produced during the day; both of these were from Region 782 (S17W45) which appears to be decaying slowly. Region 783 (S03E04) continued to grow and is currently the largest group on the disk, but did not produce any flares. The region has developed significant spots with penumbra between the leader and trailer parts of the group and appears to have a beta-gamma magnetic class. Region 786 ( N12E48) is the second largest group on the disk and also appears to have some magnetic complexity, but only managed to produce a B-flare. Region 785 (S18W20), which produced several C-flares yesterday, was quiet and decaying during the past 24 hours.

Solar activity is expected to predominantly low for the next three days (04-06 July) but there is a chance for an isolated M-class flare, with Region 783 or Region 786 the most likely sources.

The geomagnetic field was initially active but has been quiet to unsettled since 03/0600 UTC. The high speed stream continues to weaken as velocities steadily decreased today; values at forecast issue time were around 480-500 km/s.

The geomagnetic field is expected to be mostly unsettled with a chance for some isolated active periods for the first day (04 July). Conditions should decline to predominantly quiet for the second and third days (05-06 July).
