Highlights of Solar and Geomagnetic Activity 09 - 15 July 2018
Solar activity was very low throughout the reporting period. The visible disk produced several plage regions but no visible spots were observed. No proton events were observed at geosynchronous orbit The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels. Moderate levels were reached on 09-11 Jul and 13-17 Jul.
Geomagnetic field activity was mostly quiet with several periods of unsettled observed on 11-12 Jul. A slow-moving transient signature was observed in the solar wind midday on 10 Jul from a CME first observed in STEREO AHEAD COR 2 imagery early on 05 Jul. A decrease in solar wind speeds was observed, after the onset, which lowered winds from near 385 km/s to 309 km/s at its slowest point on 11 Jul. Total magnetic field strength peaked at arrival with 13 nT. Bz was mostly oriented either near neutral or northward which produced a quiet to unsettled geomagnetic response throughout the duration of the transient.
Forecast of Solar and Geomagnetic Activity 16 July - 11 August 2018
Solar activity is expected to remain very low throughout the outlook period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to range from moderate to high levels. Moderate to high level are expected over 21-31 Jul and normal to moderate levels are
expected through the remainder of the outlook period. All enhancements in the greater than 2 MeV electron flux are due to the anticipated influence of multiple, recurrent CH HSSs. The Geomagnetic field activity is expected to range from quiet to G1 (Minor) at geomagnetic storm levels. Unsettled levels are expected on 16 Jul, 21 Jul and 24 Jul. Active levels are expected on 20 Jul and 22 Jul; G1 (Minor) geomagnetic storm levels are expected on 23 Jul. All increases in the geomagnetic activity are in anticipation of multiple, recurrent CH HSSs.
