Highlights of Solar and Geomagnetic Activity 13 - 19 November 2023
Solar activity ranged from low to moderate levels. Low levels were observed on 13, 15-17 and 19 November. Moderate (R1-minor) levels were observed on 14 and 18 November. Region 3485 (S19, L=205, class/area Dai/080 on 12 Nov) produced an M1.0/Sn at 14/2305 UTC. New Region 3490 (N23, L=355, class/area Eac/150 on 19 Nov) produced three M-class flares; an M1.2 at 19/0542 UTC, and M1.1 at 19/1644 UTC and an M1.0 at 19/2233 UTC.
Early on 16 November, dimming was observed near N10W15. An associated CME was observed in SOHO/LASCO C2 imagery off the WNW limb at 16/0336 UTC. Model analysis of this CME suggested likely Earth impact early on 20 November.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels.
Geomagnetic field activity was at mostly quiet to unsettled levels with isolated active and minor storm (G1-minor) levels early on 13 November. The isolated active and minor storm levels was due to waning CME influence. The remainder of 13 November through 15
November was at quiet to unsettled levels due to positive polarity CH HSS influence. Mostly quiet levels were observed on 16-19 November.
Forecast of Solar and Geomagnetic Activity 20 November - 16 December 2023
Solar activity is expected to be at very low to low levels with a chance for moderate levels from 20 November to 01 December and again from 14 to 16 December.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 25 November through 09 December due to CH HSS influence.
Geomagnetic field activity is expected to be at unsettled to G1 (minor) levels on 20 November due to likely CME influence. Unsettled to isolated active levels are expected on 21-25 and 27-28 November and 04-07 and 12-13 December due to CH HSS inf
