Here is this week's space weather and geophysical report, issued 2019 Dec 02 0130 UTC.

Highlights of Solar and Geomagnetic Activity 25 November - 01 December 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 reached high levels on 25-28 Nov and decreased to moderate levels on 29 Nov - 01 Dec.

Geomagnetic field activity was mostly quiet. A single isolated period of unsettled was observed late on 29 Nov in response to a prolonged period of southward Bz.

Forecast of Solar and Geomagnetic Activity 02 December - 28 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 range from moderate to high levels. High levels are expected to be reached on 20-25 Dec in response to CH HSS influence; moderate levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to be at quiet to active levels. Active levels are expected on 18-19 Dec due to interaction with a positive polarity CH HSS; unsettled levels are expected on 03 Dec and 20-21 Dec; quiet levels are expected for the remainder of the outlook period.
