GREATER THAN 10 MEV AND GREATER THAN 100 MEV ALERTS CONTINUE TO BE IN EFFECT FROM THE X1/3B FLARE YESTERDAY. GT 10 MEV FLUX HAS REACHED VALUES OF 209 PFU AT 25/2300UT, AND APPEARS TO REMAIN AT A CONSTANT LEVEL. GT 100 MEV FLUX HAS DECLINED FROM ITS PEAK OF 3.6 PFU AT 25/0055UT, BUT HAS REMAINED STEADY AT 0.7 PFU OVER THE LAST 12 HOURS. WHEN THE SHOCK FROM THE FLARE REACHES EARTH, PROTON DENSITIES ARE EXPECTED TO CLIMB BY 1 TO 2 ORDERS OF MAGNITUDE. THE SHOCK IS EXPECTED BETWEEN 26/1200-2400UT.

THE SOLAR ACTIVITY OCCURRING LATE ON AUGUST 24 PRODUCED A SMALL PROTON EVENT THAT EXTENDED UP TO INCLUDE VERY ENERGETIC PARTICLES. GREATER THAN 10 MEV PROTONS BEGAN RISING AT 24/2230 UT AND CROSSED THE SEC EVENT THRESHOLD AT 24/2355 UT. FLUXES REACHED A MAXIMUM OF 190 PFU AT 25/0435 UT THEN DECLINED TO ABOUT 100 PFU AND REMAIN STEADY AT THAT LEVEL. GREATER THAN 100 MEV PROTONS BEGAN RISING AT 24/2230 AND REACHED EVENT THRESHOLD AT 24/2245 UT. THESE PEAKED AT ABOUT 3.5 PFU AT 23/0055 UT BUT CURRENTLY REMAIN ELEVATED AT ABOUT ONE PFU. NEUTRON MONITOR DATA AND THE GOES ENERGETIC PARTICLE SENSOR MEASURING PROTONS ABOVE 850 MEV SHOWED A SMALL RISE BEGINNING ABOUT 24/2210 UT. THE THULE RIOMETER HAS REGISTERED BETWEEN ONE AND TWO DB ABSORPTION SINCE THE PARTICLE EVENT BEGAN. THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED. SMALL PERTURBATIONS PASS THE ACE SATELLITE AT RANDOM INTERVALS OF ABOUT ONE TO TWO HOURS. MID-LATITUDE K-INDICES HAVE RANGED FROM 1 TO FOUR OVER THE PAST 24 HOURS.
