Radio Propagation

Solar-terrestrial indices

Indices from the U.S. NOAA Space Weather Prediction Center in Boulder Colorado, updated every three hours and published here in real time:

The propagation indices are temporarily unavailable. The Propagation page is also out of use. We are very sorry for the inconvenience and hope to fix the problem soon. Meanwhile, you can get the latest solar weather situation and forecast by clicking here.

What does this mean for DXers?

Forecast: A-Index & flux

The propagation indices are temporarily unavailable. The Propagation page is also unable to retrieve the indices from NOAA. We are sorry for the inconvenience and hope that the problem will be fixed soon. Meanwhile, you can get the latest A-Index and Solar Flux forecast by clicking here.
