For those who once ventured to my "On-line HF Propagation Prediction page" and got an obscure browser error, I have good news:

The page has been recently updated with new material and is now again
compatible with most internet browser brands.

Give it a try he
http://HAMwaves.com/propagation/index.html

and see if next weekend some new sunspots will glimpse in view or find
out whether a coronal hole will produce a geomagnetic storm within a
couple of days.

Enjoy!
