Solar Forecast

(last updated 24 Jul 2016 23:30 UT)

25 Jul 26 Jul 27 Jul Activity Low to moderate Low Very low to low Fadeouts Possible None expected None expected 10.7cm/SSN 75/13 75/13 70/5 COMMENT: Solar activity was Moderate during 24 July. Active region 2567 produced two M-class flares: M2.0 peaking at 0620 UT and M1.9 peaking at 1743 UT. No Earth-directed CMEs were observed in the available SOHO LASCO imagery. Solar activity is expected to be Low to Moderate during 25 July due to a chance that AR 2567 will produce M-class flares, then it will be Low and Very Low to Low because there is a chance that C-class flares may occur. During the last 24 hours the interplanetary magnetic field Bt was almost constant, 5-8 nT, with its Bz component being predominantly positive and varying in the range from -6 to +7 nT. A relatively weak shock-like feature was observed in the solar wind at 1434 UT. The feature included an abrupt increase of the total magnetic field Bt from 5 nT to 13 nT, electron number density from 8 to 13 particles/cm3, and bulk velocity from 390 km/s to 460 km/s. During the feature crossing the Bz component varied in the range from -5 nT to +2 nT and it was negative from 1457 UT to 1740 UT. During the next UT day, 25 July, the solar wind is expected to be slightly enhanced due to coronal hole effects.
