Solar Forecast

(last updated 05 May 2015 23:30 UT)

06 May 07 May 08 May Activity High High High Fadeouts Probable Probable Probable 10.7cm/SSN 135/89 140/94 145/99 COMMENT: Solar flare activity has been high during the previous 24 hours. AR 2339 produced the largest flare of the day, an X2.7 event peaking at 22:11 UT on May 5. A 10 cm radio burst to 590 sfu occurred at the time of the X2.7 flare. AR 2339 is located on the north east limb and the associated strong CME will not be Earthward directed. AR 2335 has grown in size and complexity and produced an M2.6 flare peaking at 17:24 UT. AR 2335 and AR 2339 produced numerous lesser C class and M class flares. AR 2335 will rotate into the geoeffective zone toward the end of the week. GONG Big Bear H alpha images recorded a Disappearing Solar Filament (DSF) in the Southern Hemisphere just west of the solar meridian at 22 UT, several minutes before the X2.7 flare on the north east limb. The DSF was launched from a potentially geoeffective location. When SOHO LASCO observations become available, they may show an Earthward directed CME. The halo CME launched toward the east during May 2 is expected to arrive at Earth late today, May 6, or possibly early on May 7. The solar wind speed has been approximately 350-400 km/s. The magnitude of IMF has been steady at about 6 nT and the Bz component has been fluctuating mostly in the range -5 nT to +5 nT.
