Solar Forecast

(last updated 22 Nov 2020 23:31 UT)

23 Nov 24 Nov 25 Nov Activity Low Low Low Fadeouts None expected None expected None expected 10.7cm/SSN 90/34 92/37 94/40 COMMENT: Solar activity was low on UT day 22 November. Three C flares occurred, the largest, a C3.3. New spot region AR 2785 (S23E76) was the source of this and another flare and is an Hsx/alpha group. AR 2783 (S22E03) maintains its Hsx/alpha classification. AR 2784 (N34E16) class is Bxo/beta and has decayed. Solar activity is expected to be low. A CME was observed in STEREO A images at 0324 UT and appears faint but broad in LASCO C3. This may be related to filament activity at S30E08 at 21/1540 UT. The solar wind speed range was 485-649 km/s. The peak total IMF (Bt) was 11 nT and the north-south IMF (Bz) range +8/-10 nT, predominantly southward. The solar wind speed is expected to be moderately enhanced on 23 Nov due to continuing coronal hole effects. Coronal hole effects should begin to wane on 24 Nov. There remains the chance of a weak CME impact on 23 or 24 Nov.
