Solar Tsunami… Satellites Beware! NASA, [SATNEWS]

* Not too many people care about the activity of the sun. Amateur Radio (Ham Radio) operators that use the HF bands might care a little bit. We are a Solar Minimum, a Sunspot Cycle Minimum. But we are in Cycle 24 and on the way up.

This page: http://science.nasa.gov/science-news/science-at-nasa/2008/10jan_solarcycle24/ says: 

“Solar cycles usually take a few years to build from solar minimum (where we are now) to Solar Max, expected in 2011 or 2012.”

And this page: http://www.arrl.org/the-sun-the-earth-the-ionosphere tells you why Amateur Radio Operators would care about this. But basically radio propogation (getting distance or DX) has been in the pits for awhile. When we get to the max then supposedly a lot ham radio bands will jump to life. A lot of frequency bands will open up that haven’t been of much use maybe all the way up to VHF bands.

“allowing the ionosphere to refract higher frequencies (15, 12, 10, and even 6 meters) back to Earth for DX contacts. ”

* But anyway back to Solar Tsunami thing …

That’s a good read … supposedly this solar activity, storms even, Coronal Mass Ejections, can wreak havock on a lot of things that we take for grant it. For example modern power and communications infrastructures.

I found this video, out of many that I found on YouTube, to be interesting … even though it wasn’t a current 2010 Solar Tsunami video … it did show and explain a whole lot more about this stuff. So it got my vote:

Ericsson W35 released in the USA. This you’ve gotta SEE!!
Better looking presentation than W25 (you might not want to
hide this one in the Doghouse!) + High Speed Upload which
the W25 did not have.
