Solar Forecast

(last updated 19 Feb 2017 23:30 UT)

20 Feb 21 Feb 22 Feb Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 82/23 82/23 82/23 COMMENT: The solar activity was at very low levels during the UT day 19 February, with no notable flares. Very low levels of solar activity is expected for the next 3 days (20-23 February) with a slight chance of C-class flares. A filament eruption from near the solar centre N14E02 was observed to begin at around 19/0511 UT. However, it was not clear from the satellite imagery if this event had triggered an earth-directed CME. The solar wind speeds peaked to ~625 km/s at around 19/0300 and thereafter had exhibited a slow declining trend. This may be indicative of the beginning of the waning effects of the coronal hole. The solar wind speed at the time of writing was 550 km/s (19/2300 UT). The IMF Bt was steady near 5 nT throughout the UT day. The Bz component varied between -5 nT and +5 nT. The two outlook (20-21 February) is for the solar winds to continue to trend toward nominal levels as the coronal hole effects wane.

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