Solar Forecast

(last updated 28 Mar 2017 23:32 UT)

29 Mar 30 Mar 31 Mar Activity Low Low Low Fadeouts None expected None expected None expected 10.7cm/SSN 84/26 84/26 83/24 COMMENT: Solar activity has increased over the the last 24 hours,with several B- and C-class flares emanating from both active regions 2645(S09E44) and 2644(N13E17). Region 2644 has a beta-gamma magnetic class, it is expected to continue to produce C class x-ray flares with a slight chance of an M class flare over the next three days. The two other active regions on the visible disk show simple magnetic complexity and are not expected to produce any significant flares at this time. A number of narrow CMEs have been detected over the past 24 hours, they will not affect Earth. The solar wind speed was high, ~ 700km/s, due to a high speed stream associated with the recurrent coronal hole. The IMF Bt decreased over the last 24 hours, starting at around 8 nT and currently around 4 nT. The Bz component reached a minimum of -7 nT at 0004UT but varied for most of the day between +/-5 nT. The effect of the coronal hole is expected to keep the solar wind stream strong for the next three days.

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