In the last 24 hours Solar activity was at moderate levels. Region 3815 produced the only M-class flare of the period, a longduration M1.6 to 1F flare, at 07 to 0749 utc. Regions 3806 , 3808 and 3813 added some C-class flares, the largest being a C7.2 to 1 fflare from Region 3806 at 07 to 2119 utc. Region 3814 was the only region to exhibit growth during the period, gaining a fewperipheral spots. New Regions 3818 and 3819 were numbered this period. The remaining regions weredegenerating and inactive. The coronal mass ejection associated with the M-class flare event, mentioned in theprevious discussion, was analyzed and deemed to be heading well south ofthe ecliptic plane. No Earth-directed coronal mass ejections were observed in availablesatellite imagery. Forecast... R1-R2 radio blackout events are likely, with a slightchance for R3 or greater events, on 08 to 10 september.

In the last 24 hours The greater than 2 mega electron volt electron flux reached moderate levels. Thegreater than 10 mega electron volt proton flux remained elevated, but below the S1 threshold. The greater than 2 mega electron volt electron flux is expected to continue at normalto moderate levels on 08 to 10 september. A slight, but diminishing chanceremains for an S1 solar radiation storm on 08 to 10 september due to thecontinued elevated particle levels.

In the last 24 hours Solar wind parameters continued at background levels. Total fieldaveraged near 8 nano tesla, the Bz component observed only minor southwarddeflections to near to 7 nano tesla, and solar wind speeds dropped below 350 kilometers per secondby the end of the period. Phi was in a negative orientation. Enhancements in the solar wind environment are expected on 08 september as apositive polarity coronal hole high speed stream is anticipated to move into a geoeffectiveposition. Elevated levels are expected to continue through 09 september beforethe HSS moves out of a geoeffective location by 10 september.

In the last 24 hours The geomagnetic field was at quiet and unsettled levels. A positive polarity coronal hole high speed stream is expected to move into a geoeffectiveposition on 08 Sep, increasing conditions to quiet to unsettled levels, with active periods likely. The elevated conditions are expected topersist into 09 september. By 10 Sep, the HSS is expected to move out of itsgeoeffective position, allowing conditions to return to mostly quietlevels.
