Nobeyama Radioheliograph Event List

ResourceID
spase://NagoyaU/Catalog/NoRH/Flares

Description

The Nobeyama Radioheliograph (NoRH) Event List is a curated catalog of solar flares and radio events, featuring high-cadence microwave images (17 and 34 GHz) captured by the Nobeyama Radioheliograph in Japan. This list documents over 900 flares with 0.1-second temporal resolution and ~10-arcsecond spatial resolution, providing light curves, polarization data, and images for identifying active phenomena.
