Researchers from the Purple Mountain Observatory (PMO) of the Chinese Academy of Sciences and the Italian National Institute for Astrophysics have proposed a new method to measure moderately saturated sources of the Ultra-Violet Optical Telescope onboard the Swift satellite (Swift/UVOT), and identified GRB 220101A as the most energetic ultraviolet/optical flare ever detected. The study was published in Nature Astronomy on June 26.
