My Top 4 auroras of Solar Cycle 25:

#1 - 10-11 May 2024 G5 Gannon storm
#2 - 10-11 October 2024 G4 storm
#3 - 19-20 January 2026 G4 storm
#4 - 5 November 2023 G3 storm (tied with the 11-12 November 2025 G4)

Yours? 

The most interesting part? All of the aurora of SC25 happened in the last three years. All of the action, big geomagnetic storms, big aurora - only the last 3 years.

AR 4566 decays + new development! 4566 has decayed quite significantly over the past 24 hours, particularly in the intermediate part. It has lost magnetic complexity and polarity mixing. The rate of flaring and X-ray flux have dropped somewhat. Meanwhile, AR 4568 is showing some growth (trailing AR 4566).

#OTD: 22 years ago - we got a short break in clouds during the G4 storm and some aurora. View from Križna Gora, NW Slovenia. A brief, seven minute appearance, but I still remember it vividly. Photos: Jure Zakrajšek.

What a spectacle! And how different high latitude auroras are from mid and low-latitude auroras.

#OTD: 22 years ago - the thrid day of intense geomagnetic activity, with a second high-end G4 storm (Kp=9- reached twice, DSTmin = -263 nT). This was #10 storm of SC23. It would currently be #3 of SC25. Did you see it?
