PROPAGATION INFORMATION

Everything we do on the air depends on propagation. If propagation is good, we work the DX, if it's poor, we complain about it. On this page we have a movie of the sunspot activity on the Sun for the latest 48 hours (NASA/SOHO keep changing the available movies so expect anything), current propagation data, predictions of conditions for the next 24 hours, a table of solar and ionospheric activity for the past 4 months or so, the very latest K-index and X-Ray data from NOAA/SEC, a graph showing the progression of the latest sunspot cycle, a movie of almost the entire 360 degrees of the Sun's surface from the STEREO satellite, and the latest WWV propagation bulletin. See the description page for a brief explanation of the data.
