Solar activity decreased to very low levels. Region 1226 (S20W81) produced an isolated B-class flare. Region 1226 continued to gradually decay as it approached the west limb and was classified as a 1-spot Axx type. The remaining numbered regions were inactive. No new regions were numbered.

Solar activity is expected to be very low through the period (09 - 11 June).

Geomagnetic activity was at quiet to minor storm levels. Unsettled to minor storm levels occurred during 07/2100 - 08/0600Z, associated with elevated solar wind speeds combined with increased IMF Bt and periods of southward IMF Bz. Mostly quiet conditions occurred after 08/0600Z. The greater than 10 MeV proton event that began at 07/0820Z reached a maximum of 73 pfu at 07/1820Z and ended at 08/1710Z. The greater than 100 MeV event that began at 07/0735Z reached a maximum of 4 pfu at 07/1025Z and ended at 08/0210Z.

Geomagnetic activity is expected to be at quiet to active levels on day 1 (09 June) due to the arrival of the halo coronal mass ejection (CME) observed on 07 June. Unsettled to active levels are expected on day 2 (10 June) with a chance for minor to major storm levels as CME effects persist. Activity is expected to decrease to quiet to unsettled levels on day 3 (11 June) with a chance for active levels as CME effects subside. There is a chance for a greater than 10 MeV proton event at geosynchronous orbit on days 1 - 2 (09 - 10 June) due to the arrival of the CME mentioned above.
