Topband: solarwind and 160 prop

[N1BUG]

Hi Wolf,

I'm not sure if I understand your question. If you are looking for 
real time solar wind monitoring, you might start here:

http://www.aurorasentry.com

I have assembled a collection of solar, solar wind, and geomagnetic 
real time data, originally to forecast and track VHF and UHF radio 
reflection from aurora. The site needs updating. I haven't had time 
for it in a while.

Of particular interest is the ACE MAG & SWEPAM plot which you can 
find on the "Solar Wind & Dst" portion of that site, or directly here:

http://www.swpc.noaa.gov/ace/MAG_SWEPAM_24h.html

The red "Bz" trace in the top panel is the north-south orientation 
of the interplanetary magnetic field. It couples most heavily with 
Earth's magnetic field (producing geomagnetic disturbance) when it 
is south oriented. Note that there are versions of this plot 
available for time spans of 2, 6, or 24 hours, 3 or 7 days.

While on the subject, I never have liked, and still do not, the ever 
popular NOAA POES Auroral Activity plots:

http://www.swpc.noaa.gov/pmap/index.html

These have to me proven very unreliable for the intended purpose of 
correlating to VHF auroral propagation, but also do not track as 
well with intensity of real time auroral disturbances at MF and HF. 
Much better I think, but not yet adopted by hams, is OVATION Auroral 
Forecast:

http://helios.swpc.noaa.gov/ovation/

or

OVATION Prime Real-Time:

http://www.ngdc.noaa.gov/stp/ovation_prime/

Unfortunately this one lacks a good map overlay and takes some 
practice to read it correctly.
