Two teams of scientists utilized several NSF NOIRLab facilities to observe the event and monitor its evolving light profile. They also used data from NSF–DOE Rubin Observatory, Palomar Observatory, and the VLA. NSF NOIRLab is managed by the Association of Universities for Research in Astronomy (AURA) and SLAC is operated by Stanford University for the DOE. France provides key support to the construction and operations of Rubin Observatory through contributions from CNRS Nucléaire & Particules. Rubin Observatory is privileged to conduct research in Chile and gratefully acknowledges additional contributions from more than 40 international organizations and teams.
