SOLAR ACTIVITY WAS LOW. THERE WERE TWO C-CLASS FLARES DURING THE PAST 24 HOURS. THE LARGEST OF THESE WAS A C4/SF AT 2009UT FROM REGION 8841 (S30W22). THIS REGION HAS SHOWN A SLOW GROWTH TREND BUT IS STILL MAGNETICALLY SIMPLE. REGION 8848 (S09E54) PRODUCED THE OTHER C-FLARE; A C1/SF AT 0659Z. THE GROUP IS SMALL BUT EXHIBITED RELATIVELY BRIGHT, OCCASIONALLY FLUCTUATING PLAGE. NEW REGION 8849 EMERGED NEAR S16E19 AS A SMALL, B-TYPE SUNSPOT GROUP. (NOTE: TODAY'S 10.7 CM FLUX READING WAS TAKEN FROM THE PENTICTON OBSERVATORY MORNING READING BECAUSE THE NOON TIME VALUE OF 152 WAS FLARE ENHANCED)

SOLAR ACTIVITY IS EXPECTED TO BE LOW. THERE IS A SLIGHT CHANCE, HOWEVER, FOR AN ISOLATED M-CLASS EVENT OVER THE NEXT THREE DAYS.

THE GEOMAGNETIC FIELD RANGED FROM UNSETTLED TO MAJOR STORM LEVELS. MOSTLY ACTIVE LEVELS HAVE DOMINATED THE MAJORITY OF THE PAST 24 HOURS, BUT A PERIOD OF MINOR TO MAJOR STORM LEVELS OCCURRED BETWEEN 0000-0300 UT AND A PERIOD OF MINOR STORM LEVELS OCCURRED BETWEEN 1200-1500 UT. TODAY'S SOLAR WIND OBSERVATIONS INDICATED THE ONSET OF HIGH SPEED, LOW DENSITY CORONAL HOLE CONDITIONS AROUND 28/0000UT: SPEEDS LEVELED TO 700-800 KM/S AND THE DENSITY FELL STEADILY DURING THE UT DAY WITH INITIAL VALUES OF 10 P/CC DECLINING TO 1-2 P/CC BY THE END OF THE REPORTING PERIOD.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE MOSTLY ACTIVE FOR THE NEXT 24 HOURS, AND IS EXPECTED TO BE UNSETTLED TO ACTIVE FOR THE SECOND AND THIRD DAYS. THE ENHANCED LEVEL OF ACTIVITY IS EXPECTED DUE TO CONTINUING CORONAL HOLE EFFECTS.
