Watching propagation change due to the flare

As you know, we had a X class flare this week with a Coronal Mass Ejection (CME).  Lots of auroras and unusual propagation phenomena as a result.  I have a profile on my 6500 that puts up 3 pan adapters with WWV at 5, 10, and 15 MHz.  Usually, I can see all three and I pick the strongest for an RX calibration, if needed.  I also use this as a  propagation indicator. 

The recent flare has spiced things up a bit.  The other day, I watched the 5MHz signal fade to nothing.  I found out later that the fade happened at about the time the CME hit Earth.  Kinda of neat to see something like that in real time. 

Tonight 5 MHz is back, 10 MHz is blasting in about 20 dB higher than usual, and 15MHz is fading in and out.

Nothing like a little “disturbance in the force” to shake things up.  And it's fun being able to look at so much spectrum at once to see it in action.

Greyline has just passed us on this side of the pond and most of digital DX is happening on 40 meters.
Hoping for openings on 30 and 20 meters...Alex - DH2ID

The NCDXF Beacon Network was built and is maintained for assessing propagation paths in the ham HF bands.  See: http://www.ncdxf.org/beacon/intro.html

Yes, I've used the beacon network in the past but its a bit more involved and takes more time.  My objective for the 3 WWV profile is to make a quick, end to end assessment of the station before proceeding.  So when I see a "dead" band I know it's not likely to be a problem with my station.
