NCEI has recently reorganized their Space Weather portfolio with improved access to centuries of Solar and Space Weather digital data that they curate, archive, and disseminate.
Scientists monitor the structure of the solar corona, the outer most regions of the Sun''s atmosphere, using radio waves (100â s of MHz to 10â s of GHz). Variations in the radiowave spectrum reveal
On February 4, 2026, the Sun unleashed an intense X4.2 solar flare, sparking significant radio blackouts across parts of Africa and Europe. This powerful eruption was triggered by sunspot group
Edited Event reports are preliminary solar event reports received at SWPC and manually reviewed and edited by the duty forecaster. SWPC compiles these lists from preliminary reports received from
A variety of datasets related to solar radio emissions.
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 NASA POWER project''s Data Access Viewer (DAV) is an interactive web-mapping application providing access to NASA solar and meteorological data.
