"As of June 2026, the delivered image quality from the Vera C. #Rubin Observatory is not yet meeting design specifications for the total system contribution to the PSF FWHM, ellipticity, and uniformity of the PSF size and shape across the field of view. A technical pathway exists to meet all of the SRD design specifications with continued work on the Active Optics System (AOS) and environment control. We present an image quality improvement plan based [on] analyses and experience from the Early Operations system optimization period, including strategy, priorities, and milestones for image quality improvements" - here it is: https://sotn-004.lsst.io/ h/t @…

From a mountaintop in Chile the Vera C. #Rubin Observatory has finally begun the revolutionary Legacy Survey of Space and Time (LSST): https://noirlab.edu/public/news/noirlab2616/ - the ten-year survey is Rubin’s signature campaign to create the most comprehensive, cinematic record of the Universe in history.

Rubin Observatory Opens Deep Window on Famous Cosmic Field: #Rubin image featuring hundreds of thousands of distant galaxies in and around the #COSMOSField marks the Observatory’s first #LSST Camera image and catalog release for science.
