Solar Weather Report

The South Canadian Amateur Radio Society (SCARS) has collected some solar weather-related information that hams can use to predict their signal propagation.

Today’s Solar-Terrestrial Weather Data

Amateur radio operators use signals that are affected by solar radiation. The good people at HAMQSL provide a great source of information that hams can use to see how the bands are going to act before they turn on the radio.

Current Solar Data

Today’s Sunspot Information

The HF radio signals used by amateur radio operators rely on the storms that occur on the Sun. The Solar and Heliospheric Observatory provides daily images of the Sun and the storms that appear on the surface. The image shown here is the current view of the Sun, and if you click on that image, you’ll view the SOHC website to learn more about the Sun.

Space Weather Information

Dr. Tamitha Skov has a great website, called, that talks about the current solar weather and the solar forecast for the coming days. So, if you’re planning a weekend activity, take a look here to make sure your radio experience is at its best.

Aurora Forecast for Alaska

The University of Alaska Fairbanks puts together a great forecast of the Aurora activity. They also have some great archives. Click here for that web page.

Images of the Sun

NASA maintains a couple of satellites that monitor the sun. One of the satellites is ahead of the earth’s path, and the other trails behind our trajectory. The rotating image combines those two visuals to give a 3D view of the activity on the sun.


ACE-HF Pro Propagation Software

ACE-HF Pro Propagation Software, by Longwave, Inc., is a great tool for the serious contest enthusiast, or DX hunter. Running this software on a Windows PC, the user can predict propagation paths between their home QTH, and any spot on the globe. You can quickly see what bands are open to your a given location, or determine when the best time to connect with your buddy across the globe. This software is developed out of Oklahoma City and is available for use anywhere in the world. Take a look and see how this can help your DX planning.

Continental US Current Band Conditions

This page,, provides current band conditions, updated every 30 seconds, on most of the HF bands. Green here is good, red means crank up the power amplifiers. After a few minutes, the page will go white, and you’ll need to hit the refresh button to tell the servers you are still watching.

Solar Activity & HF Propagation

Paul Harden NA5N has a great PDF document that talks about Solar Activity & HF Propagation. Lots of great tips and tricks to help decode the solar information, and how it can assist us hams.
