About This Report

This transient was identified by citizen scientists using the Black Hole Finder app, developed by the Dutch Black Hole Consortium. When experienced users confirm a promising candidate, the system automatically triggers follow-up observations using Las Cumbres Observatory's global robotic telescope network. These high-resolution images help astronomers characterize transient phenomena and contribute to our understanding of black hole formation.
