Solar Forecast

(last updated 25 Jun 2017 23:40 UT)

26 Jun 27 Jun 28 Jun Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 72/8 72/8 77/16 COMMENT: Solar activity was Very Low for the UT day, 25 June. Very Low solar activity is expected for the next 3 days with a slight chance of C-class flares. No Earth-directed CMEs were observed in the available LASCO imagery. The solar wind speed increased over the last 24 hours, starting at approximately 400 km/s, peaking at approximately 530 km/s, and currently around 510 km/s. The B total interplanetary magnetic field peaked at 10.7 nT at 25/1202 UT and is currently around 7 nT. The Bz component varied between -9 to 8 nT. The solar wind is expected to return to nominal values as coronal hole effects wane over the next two UT days, 26-27 June. The solar wind is expected to become enhanced on day three, 28 June, due to the influence of a small positive coronal hole located just south of the solar equator.

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