SOLAR ACTIVITY WAS LOW. ISOLATED C-CLASS FLARES OCCURRED DURING THE
PERIOD. BY AND LARGE, SUNSPOT GROUPS WERE SMALL AND
SIMPLY-STRUCTURED. ONE EXCEPTION WAS REGION 9125 (N25, L = 235,
CLASS/AREA DAI/320 ON 15 AUGUST), WHICH WAS OF MODERATE SIZE AND
MAGNETIC COMPLEXITY. THIS REGION WAS IN A STATE OF GRADUAL DECAY AS
THE PERIOD ENDED.

ACE SWEPAM DATA WERE NOT AVAILABLE DURING 16/1800 - 18/2000UTC AND
IMF DATA WERE NOT AVAILABLE DURING 17/0200 - 2200UTC DUE TO A
STATION-KEEPING MANEUVER. A TRANSIENT PASSED THE SPACECRAFT EARLY ON
15 AUGUST ACCOMPANIED BY A VELOCITY INCREASE (490 TO 610 KM/SEC) AND
INCREASED DENSITIES. IMF BZ WAS NORTH DURING MOST OF THE PERIOD.

THERE WERE NO PROTON EVENTS DETECTED AT GEOSYNCHRONOUS ORBIT DURING
THE PERIOD.

THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS AT
NORMAL TO MODERATE LEVELS.

THE GEOMAGNETIC FIELD WAS DISTURBED DURING 14/2100 - 15/0600UTC WITH
UNSETTLED TO BRIEF MINOR STORM LEVELS. UNSETTLED TO ACTIVE LEVELS
OCCURRED DURING 17/0600 - 1200UTC. QUIET TO UNSETTLED CONDITIONS

SOLAR ACTIVITY IS EXPECTED TO BE AT LOW TO MODERATE LEVELS. ISOLATED
M-CLASS FLARES WILL BE POSSIBLE SOMETIME DURING THE PERIOD.

NO PROTON EVENTS ARE EXPECTED AT GEOSYNCHRONOUS ORBIT.

THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT IS
EXPECTED TO BE AT NORMAL TO MODERATE LEVELS THROUGH MOST OF THE
PERIOD.

GEOMAGNETIC FIELD ACTIVITY IS EXPECTED TO BE AT QUIET TO UNSETTLED
LEVELS DURING MOST OF THE PERIOD, BARRING AN EARTH-DIRECTED CME.
