SOLAR ACTIVITY REMAINED AT HIGH LEVELS. REGION 8647 (S18W75) PRODUCED AN M6/1N FLARE AT 04/0557Z ASSOCIATED WITH A WEAK TYPE II RADIO SWEEP (EST. SHOCK VELOCITY 400 KM/SEC) AND A 230 SFU TENFLARE. IT ALSO PRODUCED AN M1/SF FLARE AT 04/1607Z. THIS REGION SHOWED LITTLE CHANGE DURING THE PERIOD AND WAS OF MODERATE SIZE AND MAGNETIC COMPLEXITY. REGION 8651 (N25W31) REMAINED A LARGE F-TYPE GROUP OF MODERATE MAGNETIC COMPLEXITY, BUT APPEARED TO BE SLOWLY DECAYING. IT PRODUCED TWO SUBFLARES DURING THE PERIOD. REGION 8645 (S26W66) REMAINED MODERATE IN SIZE AND MAGNETIC COMPLEXITY AND SHOWED LITTLE CHANGE AS IT PRODUCED ISOLATED SUBFLARES. NEW REGION 8660 (S34W25), A SMALL B-TYPE GROUP, WAS NUMBERED TODAY.

SOLAR ACTIVITY IS EXPECTED TO BE MODERATE. ISOLATED M-CLASS FLARES ARE POSSIBLE FROM REGIONS 8645, 8647, AND 8651. THERE IS ALSO A CHANCE FOR ANOTHER MAJOR FLARE FROM REGION 8647.

THE GEOMAGNETIC FIELD WAS AT QUIET TO ACTIVE LEVELS. A SUDDEN IMPULSE OCCURRED AT 04/0225Z (25 NT, AS MEASURED BY THE BOULDER USGS MAGNETOMETER). FIELD ACTIVITY INCREASED FOLLOWING THE IMPULSE WITH ACTIVE LEVELS DETECTED DURING THE 04/0300 - 0600Z INTERVAL. ACTIVITY DECREASED TO QUIET TO UNSETTLED LEVELS DURING THE REMAINDER OF THE PERIOD.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE AT QUIET TO UNSETTLED LEVELS THROUGH THE PERIOD. THERE APPEARED TO BE NO EARTH-DIRECTED CORONAL MASS EJECTIONS ASSOCIATED WITH THE MAJOR FLARES OF 02 AND 04 AUGUST.
