Highlights of Solar and Geomagnetic Activity
11 - 17 January 2021

Solar activity was very low throghout the period. Regions 2796
(S21,L=089, class/area=Cro/020 on 15 Jan) and 2797 (S18, L=340,
class/area=Hsx/090 on 17 Jan) produced only B-class activity
throughout the week.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
moderate levels for the highlight period.

Geomagnetic field activity reached active levels on 11-12 Jan due to
possible weak CME activity combined with recurrent coronal hole high
speed stream (CH HSS) influence. Unsettled conditions were observed
on the latter half of the 12 Jan as activity waned. Quiet conditions
were observed 13-17 Jan.

Forecast of Solar and Geomagnetic Activity
18 January - 13 February 2021

Solar activity is expected to be at very low levels during 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 20-22 Jan due to recurrent CH HSS
influence. the remainder of the period is expected to be at normal
to moderate levels.

Geomagnetic field activity is expected to reach active levels on
18-20 January due to recurrent CH HSS influences. Unsettled levels
are expected on 21 Jan, 25-26 Jan, 01-02 Feb, and 07-08 Feb. Quiet
levels are expected for the remainder of the outlook period.
