Highlights of Solar and Geomagnetic Activity 11 - 17 November 2019

Solar activity was very low. Region 2752 (S23, L=286) was numbered on 13 Nov as a unipolar group, but quickly decayed to plage. The region remained an area of plage throughout the balance of the summary 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 was at moderate levels on 11 and 13-17 Nov with normal levels observed on 12 Nov.

Geomagnetic field activity was predominately at quiet levels throughout the period under a mostly nominal wind regime. An isolated unsettled period was observed midday on 11 Nov and again
late on 17 Nov. The unsettled period late on 17 Nov was due to weak, negative polarity CH HSS influence.

Forecast of Solar and Geomagnetic Activity 18 November - 14 December 2019

Solar activity is expected to be a 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 22 Nov through 03 Dec in response to CH HSS influence. Normal to moderate levels are expected for the remainder of the outlook period.

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