Highlights of Solar and Geomagnetic Activity 19 - 25 November 2018
Solar activity was was very low throughout the summary period. Region 2727 (N01, Lo=110, class/area Cao/beta on 17 Nov),the largest region, produced no significant flare activity before it decayed to plage on 20 Nov. 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 background levels throughout the summary period.
Geomagnetic field activity ranged from quiet to unsettled. A weak, negative polarity high-speed stream produced isolated unsettled periods on 20-21 Nov. Quiet conditions were observed throughout the remainder of the summary period.
Forecast of Solar and Geomagnetic Activity 26 November - 22 December 2018
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. Moderate levels are expected on 07 Dec and 14-16 Dec; high levels are expected on 02-06 Dec and 08-13 Dec. The remainder of the forecast period is expected to be at normal levels. All enhancements in electron flux are anticipated in response to multiple, recurrent coronal hole
high-speed streams.
Geomagnetic field activity is expected to range from quiet to G1 (Minor) geomagnetic storm levels. G1 (Minor) geomagnetic storm levels are expected on 02 Dec; active conditions are expected on 01
Dec and 07-08 Dec; unsettled conditions are expected on 26-27 Nov, 03-06 Dec, 09 Dec and 17-18 Dec. Quiet conditions are expected for the remainder of the outlook period. All enhancements in geomagnetic activity are expected in anticipation of multiple, recurrent,
coronal hole high-speed streams.
