Solar and Propagation Data

The DXrobot is a free and strictly non-commercial service to the VHF ham radio community provided by Allard, PE1NWL. Every 5 minutes, the DXrobot retrieves the latest DX spots from the DX Summit website and the 144 MHz Propagation Logger and scans all the spots for any Aurora or E-skip related text.

If the number of E-skip or Aurora related spots per time interval exceeds a certain threshold this Propagation Monitor will show an alert and DXrobot will immediately post a short warning email to subscribers to the E-skip or Aurora warning mailinglist.

Visit the DXrobot website for more detailed information and/or to obtain a free subscription to these services.

The graph below, prepared by Jan Alvestad of the DX Listeners Club, shows the solar flux values, sunspot number and planetary A index during the past two months and is generally updated once a day. Pay a visit to the Solar Page of the DXLC for more information on recent solar events as well as predictions for the next days. Charts of all sunspot cycles from cycle 1 are also available as well as comparisons of the most recent cycle with previous cycles.
