Weekly Propagation Summary – 2019 Apr 29 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2019 Apr 29 0213 UTC.
Highlights of Solar and Geomagnetic Activity 22 – 28 April 2019
Solar activity was very low throughout the reporting period. No spotted regions were observed on the solar disk. 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 moderate levels on 22-23 Apr and decreased to normal levels for the remainder of the reporting period.
Geomagnetic field activity ranged from quiet to unsettled. A solar sector boundary crossing was observed late on 23 Apr which caused several periods of unsettled early into 24 Apr. No other significant signatures were observed in the solar wind data. Quiet conditions were observed for the remainder of the reporting period.
Forecast of Solar and Geomagnetic Activity 29 April – 25 May 2019
Solar activity is expected to be at very low levels over 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 02-12 May; moderate levels are expected on 29 Apr-01 Mar and 13-23 May. The remainder of the outlook period is expected to be at normal levels.
Geomagnetic field activity is expected to range from quiet to active levels. Active levels are expected on 01-02 May and 07 May; unsettled levels are expected on 30 Apr, 03 May, 05-06 May, 08-10 May and 19 May. The remainder of the outlook period is expected to be at quiet levels. All enhancements in geomagnetic activity are due to the anticipation of multiple, recurrent CH HSSs.
