Highlights of Solar and Geomagnetic Activity 23 - 29 December 2019
Solar activity was very low. New Region 2753 (S29, L=122, class/area Bxo/010 on 25 Dec) developed on the visible disk on late on 23 December while Region 2754 (N25, L=191, class/area Axx/010 on 25 Dec) developed on 24 Dec. Both regions were inactive and decayed to plage on 26 Dec. No Earth-directed CMEs were observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels on 27-29 Dec and reached moderate levels on 23-26 Dec. The maximum flux of the period was 462 pfu observed at 25/1810 UTC.
Geomagnetic field activity ranged from quiet to unsettled levels. A slight enhancement in solar wind parameters occurred beginning late on 25 Dec as a weak negative polarity coronal hole high speed stream (CH HSS) became geoeffective. Total field increased to a maximum of 9 nT at 25/1920 UTC while solar wind speed reached a maximum of 415 km/s at 26/1435 UTC. The geomagnetic field responded with an isolated unsettled period early on 26 Dec.
Forecast of Solar and Geomagnetic Activity 30 December - 25 January 2020
Solar activity is expected to continue at very low levels.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels on 06-14 and 23-25 Jan while moderate levels are expected on 30 Dec-05 Jan and 15-22 Jan.
Geomagnetic field activity is expected to reach unsettled levels on 30 Dec-01 Jan due to weak CH HSS activity. Unsettled to active levels are expected on 14-15 Jan due to recurrent CH HSS activity.
