Forecast Discussion :Issued: 2017 Aug 14 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity was very low. Region 2670 (S07W85, Hsx/alpha) remained quiet and stable over the past 24 hours. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to continue at very low levels over the next three days (14-16 Aug). Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was steady at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to high levels on days one through three (14-16 Aug) following elevated solar wind speeds from the CH HSS. The greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period. Solar Wind .24 hr Summary... Solar wind parameters, as measured by the DSCOVR spacecraft, continued to indicate the weak influence of a negative polarity CH HSS. Total magnetic field strength was fairly steady at 4-6 nT. The Bz component was variable between +/-5 nT. Solar wind speeds were mostly between 550-600 km/s. Phi angle was oriented in a negative sector. .Forecast... A gradual decrease in solar wind speeds will likely be observed through day one (14 Aug) and into nominal conditions on day two (15 Aug) as CH HSS influences wanes. Another enhancement is expected late on day three (16 Aug) due to the beginning effects of a CIR followed by a recurrent, polar connected, positive polarity CH HSS. Geospace .24 hr Summary... The geomagnetic field was quiet. .Forecast... The geomagnetic field is expected to be mostly quiet on days one and two (14-15 Aug) with an isolated unsettled period possible on day one. Unsettled conditions are expected late on day three (16 Aug) due to the arrival of a CIR and the onset of a recurrent polar connected, positive polarity CH HSS.
:Product: Geophysical Alert Message wwv.txt :Issued: 2017 Aug 14 0610 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # # Geophysical Alert Message # Solar-terrestrial indices for 13 August follow. Solar flux 68 and estimated planetary A-index 7. The estimated planetary K-index at 0600 UTC on 14 August was 1. No space weather storms were observed for the past 24 hours. No space weather storms are predicted for the next 24 hours.
