Highlights of Solar and Geomagnetic Activity
27 January - 02 February 2020

Solar activity was very low. Region 2757 (N05, L=089, class/area
Cso/100 on 27 Jan) decayed to played before rotating around the W.
limb. 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 was at
normal to moderate throughout the reporting period.

Geomagnetic field activity range from quiet to active. Isolated
active conditions were observed on 30 Jan while unsettled conditions
were observed on 28-27 Jan, 31 Jan and 02 Feb. Solar wind
measurements suggested all enhancements in geomagnetic activity were
in response to intermittent influence from the Southern Crown
coronal hole. The remainder of the reporting period was quiet.

Forecast of Solar and Geomagnetic Activity
03 February - 29 February 2020

Solar activity is expected to be very low 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 to high levels. High levels are
expected on 07-13 Feb, in response to a negative polarity CH HSS.
The remainder or the outlook period is expected to be at normal to
moderate levels.

Geomagnetic field activity is expected to range from quiet to active
levels. Active conditions are likely on 06 Feb and 26 Feb; unsettled
conditions are likely on 07-09 Feb, 25 Feb and 27 Feb. Enhancements
in geomagnetic activity are in response to influence from multiple,
recurrent, coronal hole high speed streams. The remainder of the
outlook period is expected to be at quiet levels.
