Highlights of Solar and Geomagnetic Activity 02 - 08 October 2017

Solar activity was at low levels. Region 2683 (N13, L=111,  class/area Cko/330 on 03 Oct) produced the strongest flare of the period, a C1 at 05/1341 UTC. All regions remained relatively simple
as they rotated off the visible disk, leaving no sunspots groups by the end of the reporting period. 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 ranged from moderate to high levels. High levels were observed from 02-05 Oct while moderate levels were observed from 06-08 Oct. High levels were associated with activity from a positive polarity CH HSS.

Geomagnetic field activity was at quiet to active levels. A single active period was observed on 02 Oct from the influence of a positive polarity CH HSS. Quiet to unsettled levels were observed
from 03-06 Oct while only quiet conditions were observed for the remainder of the reporting period.

Forecast of Solar and Geomagnetic Activity 09 October - 04 November 2017

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 normal background to very high levels. Very high levels are expected on 27 Oct; high levels are expected on
12-21 Oct, 25-26 Oct and 28 Oct - 01 Nov; moderate levels on 09-11 Oct, 23-24 Oct and 02-04 Nov. Normal levels are expected on 22 Oct. All enhancements in electron flux are anticipated from multiple, recurrent CH HSSs.

Geomagnetic field activity is expected to range from quiet to G2 (Moderate) geomagnetic storm levels. G2 (Moderate) conditions are likely on 13 Oct and 24-25 Oct; G1 (Minor) conditions on 11-12 Oct and 14 Oct; active levels on 15 Oct and 26-27 Oct; unsettled conditions on 10 Oct, 16 Oct, 28-29 Oct and 01-02 Nov. All enhancements in geomagnetic activity is anticipated in response to multiple, recurrent CH HSSs. The remainder of the outlook period is expected to be at quiet levels under a nominal solar wind environment.
