SOLAR ACTIVITY BECAME MODERATE. REGION 8392 (S23W05) PRODUCED A M1/2N AT 27/0743Z. THIS EVENT HAD MODERATE CENTIMETRIC BURSTS INCLUDING 390 SFU'S AT 2695 MHZ. A TYPE II SWEEP WITH 700 KM/S SHOCK SPEED WAS ALSO OBSERVED WITH THIS EVENT. THE NORTHERN HALF OF A 15 DEGREE LONG FILAMENT SHOWED STRONG LINEAR CHANGE SHORTLY BEFORE THE FLARE BEGAN AND ERUPTED AS THE FLARE OCCURRED. REGIONS 8395 (N19E44) EXHIBITED LITTLE CHANGE IN THE PAST 24 HOURS AND CONTINUES TO PRODUCE OCCASIONAL MINOR C-CLASS SUBFLARES. REGION 8393 (S19E24) MAINTAINS A BETA-GAMMA CONFIGURATION IN A MODERATE-SIZED F-TYPE SPOT GROUP. IT DEVELOPED FURTHER MAGNETIC COMPLEXITY ALONG THE EASTERN PORTION OF THE REGION AND THE SOUTHERN EDGE OF THE LEADER SPOTS WHERE FREQUENT FLUCTUATIONS AND SURGES WERE NOTED. REMAINDER OF THE DISK AND LIMB WAS QUIET.

SOLAR ACTIVITY IS EXPECTED TO REMAIN LOW TO MODERATE. REGION 8395 WILL CONTINUE TO BE THE PRIMARY FLARE PRODUCER WITH THE BEST CHANCE OF ISOLATED LOW M-CLASS ACTIVITY. REGION 8393'S RECENT GROWTH BEARS WATCHING - MOSTLY C-CLASS FLARES EXPECTED WITH A SMALL CHANCE FOR A LOW M-CLASS. REGION 8392 WAS IN DECAY WHEN THE M1/2N FLARE OCCURRED. THE REGION CONTINUES TO DECAY SLOWLY - FURTHER M-CLASS ACTIVITY IS UNLIKELY.

THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED

THE GEOMAGNETIC FIELD SHOULD REMAIN QUIET TO UNSETTLED FOR DAY 1 AND 2. ACTIVE CONDITIONS MAY DEVELOP ON DAY 3 IN RESPONSE TO THE M1/2N FLARE OBSERVED TODAY.
