Highlights of Solar and Geomagnetic Activity 20 - 26 January 2025
.jpg)
Solar activity ranged from low to moderate levels (R1-Minor). Moderate levels were observed on 21 Jan from Region 3967 (S14, L=148, class/area Eai/110 on 21 Jan) with an M3.3/Sf observed at 21/1039 UTC. This flare also produced a Type II sweep with an estimated shock velocity of 565 km/s. Region 3961 (S09, L=181, class/area Fkc/800 on 20 Jan) produced an M1.3/1f at 22/1108 UTC with a Type II sweep with an estimated shock velocity of 561 km/s. This region also produced an M2.7/1f flare at 24/2104 UTC. All other active regions were either quiet or contributed only C-class events. Potential Earth-directed CMEs were observed on 21 and 22 Jan.
No proton events were observed at geosynchronous orbits.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 20, 22, and 23 Jan. Normal to moderate levels were observed on 21 and 24-26 Jan.
Geomagnetic field activity was at quiet to active levels. Isolated active periods were reached on 20 Jan with unsettled levels observed on 20-24 Jan. Quiet levels were observed on 25-26 Jan. All elevations in geomagnetic activity were attributed to influence from multiple, negative polarity CH HSSs.
