Weekly Propagation Summary – 2019 Oct 28 16:10 UTC

Weekly Propagation Summary (2019 Oct 28 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2019 Oct 28 0109 UTC.

Highlights of Solar and Geomagnetic Activity 21 – 27 October 2019

Solar activity was very low. The solar disk was spotless throughout the period. A faint, slow-moving, possibly Earth-directed CME was observed in satellite imagery at 25/0654 UTC, with a potential arrival late on 29 Oct or early on 30 Oct.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 25-27 Oct with a peak flux of 36,223 pfu observed at 27/1900 UTC. Electron flux was at normal levels throughout the remainder of the reporting period.

Geomagnetic field activity reached G2 (Moderate) storm levels on 25 Oct, G1 (Minor) storm levels on 26 Oct, and active levels on 24 Oct in response to a recurrent, positive-polarity CH HSS. Quiet to unsettled conditions were observed throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 28 October – 23 November 2019

Solar activity is expected to be 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 28-31 Oct, and 21-23 Nov, with moderate levels on 01-15, and 20 Nov, in response to coronal hole high speed stream (CH HSS) influence.

Geomagnetic field activity is expected to reach G1 (Minor) storm levels on 21-22 Nov, with active levels on 28-30 Oct, and 20, 23 Nov, due to recurrent CH HSS activity. Quiet to unsettled conditions are anticipated throughout the remainder of the outlook period.
