AURORA ALERT] G1 (MINOR) GEOMAGNETIC DISTURBANCE IN PROGRESS (21 March, 2026)

https://www.sws.bom.gov.au/ 

A minor geomagnetic storm (G1) with a Kindex of 5 is presently ongoing. And sure, it is daylight. 

If this storm persists and strengthens (there’s a prediction of G3 main storm ranges), there’s a sturdy chance of aurora.  

As I wrote earlier than, the Moon is in crescent part and won’t intrude with seeing aurora within the night and early morning.  Maintain an eye fixed out and be affected person, because the magnetic polarity of the wind fluctuates considerably and aurora might come and go.

As of now the photo voltaic wind circumstances are:
Photo voltaic Wind Parameters Used:
   Date: 21 03 2026 0601 UT
   Velocity:   452 km/sec
   Bz:   -3.0 nT
   Density =    8.0 p/cc

Calculated Info from Photo voltaic wind parameters:
   Magnetopause Stand Off Distance  =   10.6Re
   Photo voltaic Wind Dynamic Strain Dp =   1.36nPa

Darkish sky websites have the perfect likelihood of seeing something, and at all times enable round 5 minutes in your eyes to grow to be darkish tailored.

As at all times look to the south for shifting pink/inexperienced glows, principally inexperienced for the time being.
