=================================== Weekly Space Weather Highlights =================================== 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.
