SOLAR ACTIVITY REMAINED AT MODERATE LEVELS. REGION 8603 (S14W11) SHOWED MINOR GROWTH AND A SLIGHT MIXING OF POLARITIES. IT PRODUCED TWO IMPULSIVE M-CLASS FLARES DURING THE PERIOD. THE FIRST WAS AN M1/1B AT 30/1130Z ACCOMPANIED BY MODERATE DISCRETE RADIO EMISSION AND A FAINT HALO-CME. THE SECOND WAS AN M2/2B PARALLEL-RIBBON FLARE AT 30/1808Z ASSOCIATED WITH MINOR DISCRETE RADIO EMISSION. REGION 8611 (S26E21) CONTINUED TO GROW GRADUALLY AND PRODUCED AN M2/1N FLARE AT 30/0446Z WITH MINOR DISCRETE RADIO EMISSION. THE FINAL M-CLASS FLARE OF THE PERIOD WAS AN M1/SF AT 30/2012Z FROM REGION 8598 (N24W49) WITH MODERATE DISCRETE RADIO EMISSION. REGION 8598 DISPLAYED GRADUAL DECAY PRIOR TO THE FLARE. REGION 8602 (N18W20) SHOWED A SLIGHT INCREASES IN PENUMBRAL COVERAGE AND MAGNETIC FIELD INTENSITY. IT PRODUCED ISOLATED SUBFLARES, NONE OF WHICH WERE ASSOCIATED WITH SIGNIFICANT X-RAY EMISSION. BRIGHT SURGING WAS SEEN NEAR NE18 AROUND 30/1230Z AND MAY PORTEND THE RETURN OF OLD REGION 8569 (N19, L=189), WHICH WAS OF MODERATE SIZE AND MAGNETIC COMPLEXITY DURING ITS PREVIOUS ROTATION. NEW REGION 8613 (N18E67) WAS NUMBERED.

SOLAR ACTIVITY IS EXPECTED TO REMAIN AT MODERATE LEVELS. ISOLATED, LOW-LEVEL M-CLASS FLARES ARE LIKELY. THERE IS ALSO A SLIGHT CHANCE FOR A MAJOR FLARE SOMETIME DURING THE PERIOD.

THE GEOMAGNETIC FIELD WAS AT MOSTLY QUIET LEVELS.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE AT QUIET TO UNSETTLED LEVELS. THERE IS ALSO A CHANCE FOR ACTIVE LEVELS DURING THE LAST TWO DAYS OF THE PERIOD IN RESPONSE TO THE HALO-CME MENTIONED ABOVE.
