Highlights of Solar and Geomagnetic Activity
11 - 17 March 2019

Solar activity was very low throughout the period. Region 2734 (N09,
L=60, class/area=Cro/60 on 06 Mar) briefly contained spots early
this period, but was quiet. A slow-moving CME off the east limb
observed early on 12 Mar was determined to have a possible
earth-directed component with an early 17 Mar arrival, based on
ENLIL model output. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 11-12 Mar. 

Geomagnetic field activity reached G1 (Minor) geomagnetic storm
levels early on 17 Mar, likely due in part to the arrival of the 12
Mar CME. Quiet to active conditions were observed on 16 Mar and
quiet or quiet to unsettled conditions were observed throughout the
remainder of the period. 

Forecast of Solar and Geomagnetic Activity
18 March - 13 April 2019

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 reach very high levels on 29-30 Mar with high levels
expected on 27-28, 31 Mar and 01-07 Apr. 

Geomagnetic field activity is expected to reach G1 (Minor)
geomagnetic storm levels on 27-28 Mar and active conditions are
expected on 26, 29 Mar and 12 Apr, all due to the influence of
multiple recurrent CH HSSs.
