Solar Forecast

(last updated 30 Jul 2014 23:48 UT)

31 Jul 01 Aug 02 Aug Activity Low Low Low Fadeouts None expected None expected None expected 10.7cm/SSN 155/109 160/114 160/114 COMMENT: Solar activity was Low over the last 24 hours with region 2127 (S08E36) being the source of the largest event with a C9.0 flare at 1617UT. Region 2127 along with regions 2130 (S07E57) and 2125 (S13E18) each produced smaller C-class events. A long NE quadrant filament erupted between 0430UT-0530UT (as seen on the Learmonth H-alpha imagery) with an associated northerly directed partial halo CME that may provide a glancing blow on 02Aug. There are currently 7 numbered regions on the visible disk with no observed change in magnetic complexity or increase in size over the last 24 hours. The solar wind gradually declined from 340km/s at 00UT to be ~300km/s at the time of this report. Solar wind speed is expected to remain <400km/s for the next 24hrs. The IMF Bz component ranged between +5 and -3nT over the UT day. Solar activity for the next 3 days is expected to be Low, with a chance of M-class events.

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