Highlights of Solar and Geomagnetic Activity
06 - 12 January 2020

Solar activity was very low. Region 2755 (S34, L=355, class/area
Bxo/020 on 03 Jan) decayed to plage on 07 January and was absent of
significant flare activity during the period. New Region 2756 (N22,
L=017, class/area Cro/030 on 09 Jan) produced dual B1 flares at
10/1159 UTC and 10/1445 UTC before decaying to plage on 11 January.
Both regions, one in the northern hemisphere and one in the southern
hemisphere, presented in satellite imagery with reverse polarity
magnetic field structure. 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
moderate levels on 09-12 Jan due to coronal hole influence. Normal
levels were observed on 06-08 Jan.

Geomagnetic field activity reached active levels on 06 and 09 Jan,
unsettled levels on 08 and 10 Jan due to influence from negative
polarity CH HSS activity. Quiet conditions prevailed throughout the
remainder of the reporting period.

Forecast of Solar and Geomagnetic Activity
13 January - 08 February 2020

Solar activity is expected to remain at very low levels.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach moderate levels on 13-22 Jan and 05-08 Feb due to
recurrent CH HSS influence. Normal levels are expected throughout
the remainder of the outlook period.

Geomagnetic field activity is expected to reach active levels on
14-15 Jan and 02-04 Feb, with unsettled conditions on 13, 16 Jan and
01, 05 Feb due to recurrent CH HSS activity. Quiet conditions are
expected throughout the remainder of the period.
