Weekly Propagation Summary (2018 Mar 12 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Mar 12 0049 UTC.

Highlights of Solar and Geomagnetic Activity 05 – 11 March 2018

Solar activity was very low throughout the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels on 10 Mar with normal levels observed through the remainder of the week.

Geomagnetic field activity reached active levels late on 09 Mar and early on 10 Mar due to the combined influences of a coronal hole high speed stream and a weak transient solar wind feature.

Forecast of Solar and Geomagnetic Activity 12 March – 07 April 2018

Solar activity is expected to continue at very low levels 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 reach high levels on 18-25 Mar with moderate levels expected on 17, 26-30 Mar. Normal flux levels are expected throughout the remainder of the outlook period.

Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 18 and 26 Mar and active levels are expected on 15-17, and 21 Mar due to the influences of multiple, recurrent coronal hole high speed streams. Generally quiet and quiet to unsettled conditions are expected for the rest of the outlook period as a nominal solar wind regime prevails.
