THE BANDS RIGHT NOW — LIVE MAP & SPACE WEATHERlive map by Jose CT1BOH from PSK Reporter data · imagery from NOAA SWPC

SWX OVERVIEW · X-RAY / PROTON / GEO
NOAA space weather overview: solar wind, Kp index, and X-ray flux panels
AURORAL OVAL · NORTH POLE
NOAA OVATION aurora forecast, northern hemisphere: the auroral oval over the north pole
AURORAL OVAL · SOUTH POLE
NOAA OVATION aurora forecast, southern hemisphere: the auroral oval over the south pole
When the ovals swell, the polar paths close and the low bands get loud. After Jose CT1BOH, who teaches it at Contest University.

THE GRAY LINEour namesake
Twice a day the terminator sweeps your QTH — and for those minutes, low-band signals ride the boundary between day and night ionosphere with absurdly low loss. 160M and 80M openings that shouldn't exist, do. That's the gray line. It's why we're named Greyline.
