SIDC URSIGRAM 30813 SIDC SOLAR BULLETIN 13 Aug 2003, 1230UT SIDC FORECAST (valid from 1230UT, 13 Aug 2003 until 15 Aug 2003) SOLAR FLARES : Eruptive (C-class flares expected, probability >= 50%) GEOMAGNETISM : Quiet (A<20 and K<4) SOLAR PROTONS : Warning condition PREDICTIONS FOR 13 Aug 2003 10CM FLUX: 118 / AP: 015 PREDICTIONS FOR 14 Aug 2003 10CM FLUX: 121 / AP: 010 PREDICTIONS FOR 15 Aug 2003 10CM FLUX: 125 / AP: 010 COMMENT: Geomagnetic conditions have evolved from active to quiet. The solar wind speed has decayed to 600 km/s. The interplanetary magnetic field (IMF) is pointing northwards with very short southward interruptions. For the next day geomagnetic conditions should remain quiet. We expect several C-flares from group 96 (NOAA 0431) which is still growing and from group 90 (NOAA 0424) despite it is at the limb of the disk. There is also a chance for M-flares in group 96.
