Thanks to Bob VA3QV I found this very useful website from K5BIZ.
This is the description:
The purpose of this experimental website is to provide 24-7-365 actual ( REALTIME ) band condition information to CW QRPp, QRPe and CW / SSB Contesters interested in increasing their scores. It can also be of benefit to other Radio Amateurs to determine band condtions for Nets and casual QSO's. This information is NOT based on any software predictions or any kind of satellite based readings. It's is based on a new Ionospheric sounding method called "HF Ionospheric Interferometry" which operates very similarly to the PolSAR system used by NASA.
Curious? Just go there and read and view it yourself:
Don't forget to read the INSTRUCTIONS and choose the right region. For us here in the Netherlands the UK would be best choice.
