When gravitational waves are detected by LIGO–Virgo, a notice goes out to other astronomers who then train their telescopes on that region of the sky and look for electromagnetic radiation from the merger. In 2017 the Virgo detector spotted its first signal and since then all three observatories have been upgraded. No light show.
