Solar Forecast

(last updated 25 Jul 2016 23:53 UT)

26 Jul 27 Jul 28 Jul Activity Very low to low Very low to low Very low to low Fadeouts None expected None expected None expected 10.7cm/SSN 70/5 70/5 70/5 COMMENT: Solar activity was Low over the last 24 hours with active region 2567 (located on the west limb) the source of a C1.8 flare at 0909UT. No Earth-directed CMEs were observed in the available SOHO LASCO imagery. The solar wind has been influenced by minor coronal hole effects over the last 2 days. Solar wind velocity ranged between 400-500km/s between 00UT and 17UT, declining to be ~390km/s at the time of this report. Bz underwent a sustained southward period of -4nT between 00UT-14UT and is currently fluctuating between +/-2nT. Solar wind speed is expected to remain at these levels over the next 3 days as recent coronal hole influence diminishes. Solar activity is expected to be Very Low to Low for 26July-28July.

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