OVRO-LWA is a highly versatile, multi-use radio interferometer operating in the 13–87 MHz frequency range. Its all-sky coverage enables imaging of the Sun and its extended corona (among many other radio sources across the sky), effectively making it a solar-dedicated instrument. These observations complement microwave data obtained by the Expanded Owens Valley Solar Array (EOVSA; 1–18 GHz), and enable studies of metric-decametric solar bursts, CMEs, and transients in the middle corona. Please refer to https://www.ovsa.njit.edu/ for a general overview of the solar facilities at the Owens Valley Radio Observatory.
This new data release includes calibrated solar spectral images (obtained via interferometry) and high-resolution dynamic spectra (obtained via beamforming) from 2024 April 1 to present, accessible through our data query system, along with documentation and example Jupyter notebooks to support users. We invite the community to explore these new data resources and pursue cross-facility studies and new discoveries.
