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.
