Weekly Propagation Summary – 2019 Nov 04 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2019 Nov 04 0117 UTC.
Highlights of Solar and Geomagnetic Activity 28 October – 03 November 2019
Solar activity was very low. Regions 2750 (S28, L=116, class/area = Axx/010 on 01 Nov) and 2751 (N05, L=154, class/area = Bxo/010 on 02 Nov) emerged on the solar disk, where inactive of significant flare activity, and quickly decayed to plage before the end of the reporting period. No Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached very high levels on 28 Oct, high levels on 29-30 Oct, 01-03 Nov, and moderate levels on 31 Oct, in response to recurrent, coronal hole high-speed stream (CH HSS) activity. A peak flux of 58,500 pfu was observed at 28/1755 UTC.
Geomagnetic field activity reached active levels on 31 Oct, unsettled levels on 28-30 Oct, and quiet levels on 01-03 Nov, due to CH HSS effects.
Forecast of Solar and Geomagnetic Activity 04 November – 30 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 04, 21-30 Nov, with moderate levels on 05-11, 20 Nov, and normal levels on 12-19 Nov, in response to CH HSS influence.
Geomagnetic field activity is expected to reach G1 (Minor) storm levels on 21 Nov, with active levels on 06, 20, 22-24 Nov, due to recurrent CH HSS activity. Quiet to unsettled conditions are anticipated throughout the remainder of the outlook period.
