Highlights of Solar and Geomagnetic Activity 20 - 26 November 2023
Solar activity ranged from low to moderate levels. Low levels were observed on 21-22 and 25-26 November. Moderate (R1-minor) levels were observed on 20 and 23-24 November. During the period, a total of 55 C-class and 4 M-class flares were observed from 13 different regions. Region 3492 (N19, L=345, class/area Ehi/380 on 24 Nov) was the most active region producing 23 C-class and 1 M-class flare.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at low to moderate levels during the period.
Geomagnetic field activity was at mostly quiet to unsettled levels on 20 and 23-24 November. Active, minor storm (G1-minor) and moderate (G2-moderate) levels were observed on 21-22 and 25-26 November. Quiet to minor storm levels were observed on 21-22
November due to positive polarity CH HSS influence. Minor to moderate storm levels were observed on 25 November due to CME and positive polarity CH HSS influence.
Forecast of Solar and Geomagnetic Activity 27 November - 23 December 2023
Solar activity is expected to be at very low to low levels on 02-12 December, with a chance for moderate (R1-minor) levels on 27-30 November, 01 December and 13-23 December.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach moderate to high levels on 30 November, 01-04 December and 07-09 December due to CH HSS influence.
Geomagnetic field activity is expected to be at unsettled to active levels on 27-28 November, 05-07 and 12-13 December. Unsettled to G1 (minor) levels are possible on 18-20 and 22-23 December. All activity is due to a variety of positive or negative polarity CH HSS influence.
