How to Read This Page

Best HF: higher solar flux, lower Kp/A, and no major disturbance text.

Geomagnetic worsening: higher Kp often means more unstable HF paths.

Auroral opportunity: rising Kp can improve auroral visibility and sometimes auroral VHF interest.

Band guidance: this is a simplified quick-look estimate, not a replacement for real-time listening or MUF tools.
