Owens Valley Solar Arrays — Observing Campaigns

Observing-campaign briefs from the Owens Valley Solar Arrays (OVSA), including EOVSA and OVRO-LWA. Each brief summarizes the campaign background and selected solar radio events, with quicklook spectrograms, imaging movies, and links to available data products from one or both arrays.

Campaign	Observing period (UT)	Facilities	Events	Data brief
Parker Solar Probe perihelion #29 — September 2026	2026 September 2–13	EOVSA (1–18 GHz); OVRO-LWA (approximately 13–87 MHz)	23	OVSA observations supporting PSP Encounter 29

Campaign briefs are updated as data are processed. Quicklook plots and movies provide an overview of the observations; available spectrogram and calibrated spectral-image data are linked within each brief. Additional products can be found through the EOVSA Data Browser and OVRO-LWA Solar Data Portal. See individual briefs for product details and access requirements.

The PSP perihelion #29 campaign and its supporting data products are supported by NASA’s PSP Data Support award 80NSSC26K1200. Solar operations of EOVSA and OVRO-LWA are supported by NSF award AGS-2436999.
