:Product: Forecast Discussion :Issued: 2022 Jul 19 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity was at low levels (no M class or greater flares). The four regions in the northern hemisphere, Regions 3060 (N13E22, Hsx/alpha), 3058 (N14E16, Dri/beta), 3057 (N17W21, Eki/beta) and 3061 (N23W53, Cro/beta) all underwent decay. Region 3056 (S16W42, Dri/beta) was also in decay. Region 3059 (S10E29, Csi/beta) developed a few more trailing spots but was otherwise inactive. Region 3055 (S17W84, Cao/beta) was inactive as it continued to rotate off the disk. No Earth-directed CMEs were detected in available coronagraph imagery. .Forecast... Solar activity is expected to be low with a chance for M-class flares (R1-R2, Minor-Moderate radio blackouts) and a slight chance for X-flares (R3 Strong or greater radio blackouts) through 21 Jul. Energetic Particles .24 hr Summary... The greater than 10 MeV proton flux was at background levels. The greater than 2 MeV electron flux reached moderate. .Forecast... There is a slight chance for a greater than 10 MeV proton enhancement exceeding alert thresholds (S1 Minor) through 21 Jul. The greater than 2 MeV electron flux is expected to be at moderate to high levels. Solar Wind .24 hr Summary... Solar wind parameters at DSCOVR reflected a disturbance in the IMF. Total field peaked at 15 nT and Bz deviated southward on occasion. A maximum southward deviation of -10 nT was observed. Wind speeds were generally steady around 400 km/s. Phi was mostly positive. .Forecast... The solar wind environment is expected to remain above background levels for the next three days (19-21 Jul) with ongoing activity and the arrival of a CME late on 20 Jul. Geospace .24 hr Summary... The geomagnetic field was at mostly quiet levels. .Forecast... Quiet to unsettled conditions, with isolated active periods, are forecast through 19 Jul with intermittent, weak disturbances. The likelihood of active levels increases by 20 Jul with a slow-moving CME that left the Sun on 15 Jul. Activity is expected to carry over into 21 Jul, making G1 (Minor) geomagnetic storming likely.
