Solar Report - July 14th, 2016
:Product: Forecast Discussion :Issued: 2016 Jul 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. A slow-rising B-level enhancement was observed from Region 2565 (N04E44, Hax/alpha) in the later half of the period. Further coronagraph imagery is needed to determine if CME was associated with the enhancement. All other active regions were relatively quiet and stable or in decay. . Forecast Solar activity is expected to be very low with a chance for C-class flares throughout the forecast period (14-16 Jul). . Energetic Particles (24 hr Summary) ----------------------------------- The greater than 2 MeV electron flux was at normal to high levels while the greater than 10 MeV proton flux continued at background levels. . Forecast The greater than 2 MeV electron flux is expected to be at moderate to high levels on days one through three (14-16 Jul) in response to elevated wind speeds from CH HSS activity. The greater than 10 MeV proton flux is expected to continue at background levels for the forecast period (14-16 Jul). . Solar Wind (24 hr Summary) -------------------------- Solar wind parameters, as measured by the ACE spacecraft, reflected the influence of a positive polarity CH HSS. Total magnetic field strength was predominantly between 4-6 nT. Bz was variable with no notable periods of sustained southward orientation. Wind speeds were in gradual decline, starting the period around 630 km/s and ending near 500 km/s. Phi angle was oriented in the positive sector. . Forecast Enhanced solar wind conditions are expected to continue through days one and two (14-15 Jul) due to continued CH HSS influence. Day three will likely see wind speeds trend towards ambient levels as the CH HSS effects wane. . Geospace (24 hr Summary) ------------------------ The geomagnetic field was quiet to unsettled. . Forecast The geomagnetic field is expected to be at unsettled to active levels on day one (14 Jul). Quiet to unsettled conditions should prevail on days two and three (15-16 Jul) as CH HSS influence wanes.
