“THE GRID”, a real-time space weather monitoring panel tailored for amateur radio operators, exclusively on SolarCdx.com.

If there is one page on this website you go to, make it this one. Put it up on a screen and watch it work for you.

It visually summarizes the current solar-terrestrial conditions using a 5×3 color-coded matrix of critical indices and solar measurements.

Each tile reflects a parameter that impacts HF propagation, such as solar wind speed, geomagnetic and interplanetary magnetic field components, sunspot activity, and radiation levels.

In the “SAMPLE” image,  solar wind is elevated at 762 km/sec, IMF Bx is -7.04 nT, and the Phi angle is 161°, indicating the magnetic field orientation.

The use of color (red, orange, yellow, green, and blue) communicates severity or operational significance at a glance. Each tile is clickable and will lead you to a detailed explainer page,  you can see where the data is from and what it means to HF communications.  The “GREENER” the better!

HAMS: 
This dashboard helps HF operators assess current propagation potential and risks. Look at the “SAMPLE” image on this page.

With a Kp index of 5.33 and A index at 56, conditions suggest moderate geomagnetic disturbance—confirmed by the G1 storm classification. However, the SFI at 135 and Sunspot number of 95 point to favorable ionization, meaning good propagation on higher bands like 15, 12, and 10 meters.

In our sample, the X-ray background at B9.6 and no radio blackout (R0) show that conditions remain stable for daytime operations. Meanwhile, IMF Bz at +2.36 nT and Bt at 7.81 nT suggest limited magnetic reconnection at Earth, reducing the chance of sudden HF disruptions.

Looks great from your mobile phone too! HINT: F11 makes your PC browser full screen to better see the grid or any page on SolarCdx.com 

This tool allows you to quickly judge when the bands are likely to open—or go quiet—based on hard space weather data.
