Solar Forecast

(last updated 26 Jul 2016 23:52 UT)

27 Jul 28 Jul 29 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 Very Low over the last 24 hours with the largest event being a B9.3 flare at 1535UT from a region beyond the west limb. The sun is currently spotless and there were no earth-directed CMEs observed in the available SOHO LASCO imagery. Solar wind velocity gradually declined from ~400km/s at 00UT to be ~350km/s at the time of this report. Bz ranged between +/-3nT, with sustained southward periods between 09-15UT and 17-22UT. The solar wind is currently at background ambient levels which is expected to change over the next 2 days with the arrival of two high speed solar wind streams, firstly from a northern hemisphere positioned coronal hole (within the next 12-24 hours) and secondly from a equatorial located coronal hole (in the next 36-48 hours). Solar activity is expected to be Very Low to Low for the next 3 days with only slight chance of a C-class flare.

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