SIDC URSIGRAM 30809 SIDC SOLAR BULLETIN 09 Aug 2003, 1230UT SIDC FORECAST (valid from 1230UT, 09 Aug 2003 until 11 Aug 2003) SOLAR FLARES : Active (M-class flares expected, probability >= 50%) GEOMAGNETISM : Quiet (A<20 and K<4) SOLAR PROTONS : Quiet PREDICTIONS FOR 09 Aug 2003 10CM FLUX: 134 / AP: 017 PREDICTIONS FOR 10 Aug 2003 10CM FLUX: 130 / AP: 012 PREDICTIONS FOR 11 Aug 2003 10CM FLUX: 127 / AP: 007 COMMENT: The solar wind speed is gradually decreasing. Over the past 24 hours it went down from 750 km/s to 650 km/s, a trend that is expected to continue for the next 24 hours. The interplanetary magnetic field is mostly northwards, so that in spite of the still elevated solar wind speed, we expect geomagnetic conditions to be quiet, with occasional excursions to active conditions. Solar activity has been low again over the past 24 hours, with just 2 small C-flares. Catania sunspot group 90 (NOAA 0424) has stopped growing but seems to be developing magnetic complexity. C-class flares from this group seems almost certain, and we now estimate that it has a significant chance for an M-flare as well.
