Solar Forecast

30 May 31 May 01 Jun Activity Very low to low Very low to low Very low to low Fadeouts None expected None expected None expected 10.7cm/SSN 80/20 75/13 75/13 COMMENT: Solar X-ray flare activity was Very Low during 29 May UT. Active region 2548 produced several B-class flares. The largest flare, B7.2, peaked at 0656 UT. A smaller flare, B6.5, peaked at 0904 UT and was accompanied by a CME, which does not seem to have a geoeffective component. No Earth-directed CMEs were observed in the available LASCO imagery. Expect Very Low to Low solar activity due to a chance for C-class flares. The solar wind speed varied in the range 420-550 km/s. At the time of the report it is gradually increasing and fluctuating in the vicinity of 510 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) varied in the range 3-8 nT and its component Bz was fluctuating between about -5 nT and +5 nT. For the next 24 hours expect the solar wind speed to reach values up to 550-580 km/s due to coronal hole effects.

Solar Activity levels are explained in the SWS Solar Terrestrial Glossary.
