SOLAR ACTIVITY WAS HIGH. REGION 9026 (N23W39) PRODUCED AN M5/3B EVENT AT 10/1702Z. THIS EVENT HAD AN ASSOCIATED 550 SFU TENFLARE AND A TYPE II SWEEP WITH A SPEED OF 700 KM/S. REGION 9026 HAD BEEN IN A SIGNIFICANT STAGE OF DECAY SINCE YESTERDAY AND WAS AN EAO BETA GROUP WITH APPROXIMATELY 8 SPOTS WHEN THE EVENT ABOVE OCCURRED. OTHERWISE, ONLY MINOR C-CLASS EVENTS WERE OBSERVED DURING THE PERIOD. NEW REGION 9037 (N18E51) WAS NUMBERED TODAY.

SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. REGION 9033 (N22E18) NOW APPEARS TO HAVE THE BEST POTENTIAL FOR THE PRODUCTION OF M-CLASS EVENTS.

THE GEOMAGNETIC FIELD RANGED FROM QUIET TO MINOR STORM. AT 09/2350, DATA FROM THE ACE SPACECRAFT DISPLAYED WHAT WAS PRESUMED TO BE THE ARRIVAL OF THE FAINT FULL HALO OBSERVED BACK ON 7 JUNE FROM THE X1/3B EVENT. AS A RESULT, THE GEOMAGNETIC FIELD REACHED ACTIVE TO MINOR STORM LEVELS FROM 10/0600Z - 10/1500Z. THE M-CLASS EVENT DESCRIBED IN PART IA PRODUCED PROTON EVENTS AT GREATER THAN 10 AND 100 MEV FLUX AT GEOSYNCHRONOUS ORBIT. THE GREATER THAN 100 MEV CROSSED EVENT THRESHOLD OF 1 PFU AT 10/1750Z. THE 100 MEV PEAK FLUX WAS 1.6 PFU AT 10/1755Z AND DROPPED BELOW THRESHOLD, ENDING AT 10/1830Z. THE GREATER THAN 10 MEV PROTON EVENT BEGAN AT 10/1805Z AND IS STILL IN PROGRESS AT THIS TIME. THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT REACHED HIGH LEVELS.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE PREDOMINATELY QUIET TO UNSETTLED WITH THE CHANCE OF ISOLATED PERIODS OF ACTIVE CONDITIONS. THE GEOMAGNETIC ACTIVITY MAY INTENSIFY LATE ON THE THIRD DAY IF AN INTERPLANETARY SHOCK ARRIVES AT THE EARTH FROM THE M5/3B EVENT EARLIER TODAY. FURTHER ANALYSIS OF DATA, NOT YET AVAILABLE AT THIS TIME, IS REQUIRED TO DETERMINE IF AN EARTH DIRECTED CME IS IN PROGRESS.
