There can not be a GEOMAGNETIC storm on the sun! :roll: :roll:
(Rant on) I wish science reporters knew something about SCIENCE! (Rant off) :evil: :evil:
As for the answer, the SOLAR EVENT (on the sun) will cause a GEOMAGNETIC storm on EARTH (Hence the term GEO) which can disrupt communicatuions due to noise, but will enhance the charge in the ionospere and improve some modes of transmission that rely on it!

Sometimes these storms enhance VHF and UHF propagation. There has been auroral activity the last two nights which can bring some strange conditions... Listen to your AM radio at night during such auroral events and you will find signals coming in from "strange" areas while normally strong nighttime AM stations might be totally missing. VHF is often enhanced on the ham bands (6 meters [50 mHz] in particular).
Earlier this evening, I was able to talk to buddies in Ohio and Northern Indiana on 3.87 mHz, but signals were somewhat weaker than usual. Also talked to a friend on 14.314 in Florida. He was strong, but with lots of QSB (fading).
So...what I am saying, just because the sun blows up like it just did, does not mean ALL radio will suffer. I like to look for "propagational opportunities" during such events. By the way, the K-index reached 9...Which is the highest possible level of disturbance. It will probably affect radio propagation for a few days before gradually returning to normal.
A good place to read about all this (in easy to understand lingo) is the American Radio Relay League's (ARRL) site. Here's the link:

Ah! So THAT'S why I can hear Ne State Patrol the last day or so! (42 mhz) Usually I can see them before I can hear them!
Which ain't good when it's in my rear view mirror! :shock:

You expect science from WorldNutDaily? :roll:N_Jay said:
If you aren't familiar with it, the VHF / UHF Tropospheric Ducting Forecast web page can help explain some of those unusual distant signals you hear.

Hmm... no wonder I couldn't hear squat on the HF Air bands...
Yeah, the HF bands were terrible over the weekend. I was very dissapointed after runsh shipping my new IC 718 and antenna tuner to have it for the weekend! However last night it seemed the bands had recovered somewhat. I wish I had a good 6 meter setup, it sounds like it was booming over the last couple of days.

Nothing else to do since I'm home under the weather...sucks since it's a nice day...but the HF bands are crap again today. Normally, 6577 CAR A booms in here during the early morning; it's quite feeble, as is WWV.
Guess I'm restricted to VHF/UHF today... :x

If you want to be able to see the solar situation quickly, look at the upper-left corner of http://www.n3kl.org/sun/noaa.html. I have a live link to the situation and geofield on one of my pages, http://www.Webdingers.com
