Noaa solar radio data

NOAA NCEI has solar radio legacy datasets from multiple sources over many decades, including the United States Air Force (USAF) Radio Solar Telescope Network (RSTN) stations. . The structure of the solar corona, the outermost regions of the Sun's atmosphere, can be monitored using radio waves (100's of MHz to 10's of GHz). Variations in the radio wave spectrum reveal characteristics of the corona and upper chromosphere in terms of altitude profile for the local plasma. . Edited Event reports are preliminary solar event reports received at SWPC and manually reviewed and edited by the duty forecaster. Today's list is updated every 30 minutes at 2 and 32 minutes past the hour. For further details see Solar Cycle Progression.
