Here is this week’s space weather and geophysical report, issued 2019 Nov 25 0142 UTC.

Highlights of Solar and Geomagnetic Activity 18 - 24 November 2019

Solar activity was very low. No sunspots were observed on the visible disk. No Earth-directed CMEs were observed in available coronagraph imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels on 18-23 Nov. Moderate to high levels were observed on 24 Nov in response to the influence of a positive polarity CH HSS.

Geomagnetic field activity ranged from quiet to active levels. Quiet to active levels were observed on 21-22 Nov and quiet to unsettled on 23-24 Nov due to influence from a positive polarity CH HSS. Solar wind speeds increased to above 600 km/s over 21 Nov and remained elevated but in slow decline through 24 Nov. The remainder of the reporting period was at quiet levels under nominal solar wind conditions.

Forecast of Solar and Geomagnetic Activity 25 November - 21 December 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 be at normal to high levels. High levels are expected on 25-28 Nov and again on 20-21 Dec. Moderate levels are expected on 01-17 Dec. All enhancements to electron flux are anticipated in response to multiple CH HSSs.

Geomagnetic field activity is expected to range from quiet unsettled. Unsettled conditions are expected on 25-28 Nov, 08 Dec, and 18-21 Dec in response to multiple CH HSSs. The remainder of the outlook period is expected be at quiet levels.
