Heads up - literally

| No Comments

People in Northern latitudes have a very good chance of seeing a nice Northern Lights display.
Seattle meteorologist Cliff Mass has the details:

Significant Aurora Possible Tonight
Folks in the northern half of Washington State may well see an impressive auroral display tonight.

A major Coronal Mass Ejection (CME) on the solar surface has resulted in a flux of particles moving into the earth's magnetic field.

A measure of the disturbance of the earth's magnetic field is Kp: auroral activity moving southward into our area generally requires Kp of 5 or more. The estimated value right now is 6.

Heading out around 9PM tonight.  Sit for a while to dark-adapt my eyes and see what is happening...
We do live on an amazing planet
