This web site is by Dr. Tony Phillips.
Today's Space Weather NOAA's Space Environment Center space weather page. The content of this page is somewhat technical. Includes graphs of solar activity and a 3 day space weather outlook. This is the web wolf's favorite space weather oracle.

D Layer Absorption Prediction This page is important only during the daytime or if you're trying to work into a daylit area of the world. The D-layer is not present in dark areas of the world. When it's blasted by a solar flare, it blacks out higher frequency bands in daylit parts of the world starting with the highest frequencies first. Extreme flares can wipe out the whole of the HF spectrum.
The Auroral Oval In The Northern Hemisphere A map of the aurora over the northern hemisphere. Geomagnetic storms can produce aurorae which are visible in the lower 48 states.
