Solar activity was low during the past 24 hours. There were two C-class events. The first was a C3/Sf from Region 772 (S18W44) at 1342 UTC, and the second was a C2.5 from Region 776 (S06E47) at 1914 UTC. Neither of these regions has shown dramatic changes during the past 24 hours. However, Region 776 continues to be the largest group on the disk. There was some new flux emergence and growth in Region 775 (N10E35), but the group didn't produce any flares. A quiescent filament erupted from the northeast part of the disk at about 0900 UTC and was associated with a CME observed by LASCO. The CME is centered over the northeast limb and is about 75 degrees wide: it does not appear to have any earthward directed component.

Solar activity is expected to be low, but there is a slight chance for an isolated M-class event. Regions 772 and 776 are the most likely sources for activity although Region 775 might also contribute if the current growth trend continues.

The geomagnetic field ranged from quiet to minor storm levels during the past 24 hours. The interplanetary magnetic field component Bz went through an interval between 06/1800-07/0400 UTC with weakly but persistently negative values ranging from 0 nT to -7 nT. This resulted in unsettled to active levels between 06/2100-07/0300 UTC followed by a minor storm interval from 0300-0600 UTC and another active period from 0600-0900 UTC. Conditions have been at quiet to unsettled levels since 0900 UTC. The greater than 2 MeV electron flux was at high levels during the past 24 hours.

The geomagnetic field is expected to be predominantly unsettled with a chance for isolated active periods for the first day (08 June). Conditions should be unsettled for the second day (09 June) and are expected to decrease to quiet to unsettled for the third day (10 June).
