[AURORA ALERT] GEOMAGNETIC WARNING possible G3 storm on the 23rd
After a series of disappointments where geomagnetic storms occurred after 2 am (after I had given up and gone to bed) or in the evening twilight, or in daytime there is a further chance of periods of G3 due to ongoing coronal hole effects.
While G1-G2 geomagnetic conditions are most likely, G3 may be possible for sustained southward solar wind parameter Bz. If this occurs there is a strong possibility of aurora.
The Moon is in still in crescent phase and although setting around 10 pm it will not significantly interfere with seeing aurora in the evening and early morning. Keep an eye out and be patient, as the magnetic polarity of the wind fluctuates significantly and aurora may come and go.
As of now the solar wind conditions are
Solar Wind Parameters Used:
Date: 23 03 2026 0453 UT
Velocity: 694 km/sec
Bz: 2.0 nT
Density = 2.0 p/cc
Calculated Information from Solar wind parameters:
Magnetopause Stand Off Distance = 11.8Re
Solar Wind Dynamic Pressure Dp = 0.80nPa

*****************************************************************************
Dark sky sites have the best chance of seeing anything, and always allow around 5 minutes for your eyes to become dark adapted.
As always look to the south for shifting red/green glows, mostly green at the moment.
