Solar Forecast

(last updated 22 Jul 2016 23:30 UT)

23 Jul 24 Jul 25 Jul Activity Low to moderate Low to moderate Low Fadeouts None expected None expected None expected 10.7cm/SSN 0/0 0/0 0/0 COMMENT: Solar activity was Low during 22 July. Three C-class flares were produced by active region 2567. The largest flare is C6.6 peaking at 0651 UT. A 20-degree long disappearing filament was observed in the vicinity of N24E58. The CMEs detected on 20 July do not seem to be geoeffective. No Earth-directed CMEs were found in the available SOHO LASCO imagery. Solar activity is expected to be Low to Moderate during the next 3 UT days, 23-25 July, due to a chance that AR 2565 and AR 2567 will produce relatively weak M-class flares. During 22 July the interplanetary magnetic field Bt varied in the range 6-9 nT. Its Bz component was in the range from -7 nT to 8 nT, being predominantly negative since 0325 UT to 1750 UT. The sector boundary was crossed between 1500 UT and 1720 UT. The solar wind speed varied in the range 370-460 km/s. During the next UT day, 23 July, the solar wind speed is expected to be light to moderate.
