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.
Geomagnetic field activity is expected to range from quiet to G1
(Minor) 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 geomagnetic activity are in anticipation of
multiple, recurrent CH HSSs.
