Sources for HF Propagation Information
Emily/N1DID's preferred source is:
They have a lot of information that comes from everywhere - look at the Solar Flux Index from Penticton BC, The NOAA Sunspot Number and the Solar Activity Report.
I really recommend that everyone listen/watch to the Space Weather Woman Tamitha Skov. She is awesome and will teach you more than I ever could.
QRZ has a Real Time Band Conditions page that gives the MUF and other cool stuff
