Unexpected Jump in Space Weather Kp Index! Already Unstable Earthquakes

 stock here:

Found a new site, where this guy describes the space weather in slightly different, and informative ways, then a few other favorites. 

And 2-19-21 a very unexpected (to the experts) jump in Kp to level 4 for at least 6 hours.   

"They" missed the huge pop in plasma density to 20.    And they don't understand how density affects magnetic much more than velocity or temperature.   This is not a simple fluid flow scenario, it is not like fluids flowing in a pipe in which the effects of density, speed, and temperature make fully know the reactions of the fluid and surroundings.
