Rubin Observatory Launches Real-Time Alert System
The Vera C. Rubin Observatory (NSF–DOE) released its first near-real-time astronomical alerts on Feb. 24, 2026, issuing about 800,000 notices that night and planning up to 7 million nightly. The public alert stream generates notifications within roughly two minutes from image capture and includes supernovae, variable stars, active galactic nuclei and solar-system objects. The capability enables rapid, coordinated global follow-up ahead of the LSST survey.
Scoring Rationale
Official, large-scale real-time alert launch greatly increases discovery potential; impact limited until full LSST operations and broker ecosystem mature.
