Presentation #302.01 in the session From the Photosphere to the Corona, Solar Eruptive Events.
The Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) all-sky imager, operating in the range 15-90 MHz, has recently been upgraded to add longer baselines and implement a new solar-dedicated backend to provide commensal daily solar imaging observations. The 352 antenna elements provide baselines to 2.6 km (5 arcmin resolution at 80 MHz). Modes include (1) a beamformed solar-dedicated beam at 3072 frequencies (24 kHz resolution) over the entire band at 1 ms time resolution, (2) a slow-visibility interferometric imaging mode at 10 s time resolution on all baselines for extremely sensitive imaging of slowly varying emission, and (3) a fast-visibility interferometric imaging mode at 0.1 s time resolution on baselines with 48 selected antennas for stronger bursts of more rapid variability. These capabilities are designed to fulfill the goals of the low-frequency part of the Frequency Agile Solar Radiotelescope (FASR-C), and being co-located with the Expanded Owens Valley Solar Array (EOVSA), provides unique simultaneous coverage of metric and microwave emission from the Sun. Recent examples of spectra and images from OVRO-LWA commissioning observations are shown, and plans for daily automated pipeline processing are discussed.
