Re: [californiadisasters] Geomagnetic Storm in Progress - Jet Stream Blamed For Weather Extremes

For DXers like me, the band conditions are sucky!   The peak of this solar cycle is expected late summer, then it'll wind down over the next couple years (11 year cycle, more or less).  And this is a lower than usual peak.  :-(   There was a great one two cycles ago, it was outstanding for radio. 

So far we've been fortunate.  The only big CME events have been missing us, we only caught the edges.  

One good direct spit from the sun and we're set back 100 years on the (grossly outdated and abused) power grid.  It can also slag the satellites just from smacking them with energy. 

But the aurora would be prominent in CA while we'd have no lights.   :-/

Not a California Disaster but further to answering a question -
Space is not a friendly place. I just noticed this on the ARRL site about a Coronal Mass Ejection event that will happen! Also contains a more layman's explanation of A- and K-indices.

It's a measure of solar activity upon our atomosphere. 7 indicates a relatively high level of activity (storm) which can affect High and Medium Frequency Band (2-30MHz) communications. A bad enough event as Coronal Mass ejection will cause NASA to warn ISS crews to seek shelter in protected areas of the space station and can even effect other forms of communications on earth.

can anyone tell me what this means, - WARNING: Geomagnetic K-index of 7/greater expected From: Jun 29 0515 UTC To: Jun 29 1000 Onset NOAA Scale: G3 or greater-Strong to Extreme saw this on calfirenewsblog
