Letter Re: NOAA’s Improved Solar Storm Prediction Web Site


NOAA has updated their web site with an easier to read solar storm prediction description. I’m not sure when they changed this, but I’ve found it helpful.

It breaks down into, ‘Geomagnetic, Solar Radiation, and Radio Blackout’ categories.  Instead of just giving an X# or M#, they now have scale of 1-5 (minor through extreme), with a real world description of impact  on communications and power systems.  The descriptive scales are outlined in the “NOAA Scales Activity”

For me, this is much clearer and easier than trying to figure out than some M# or X# impact.

I thought that others might find it useful. – Robert B.
