<p>On 15 December, the Large-Sized Telescope (LST) Collaboration announced through an <a href="https://www.astronomerstelegram.org/?read=16381" target=" blank">Astronomer’s Telegram (ATel)</a> the detection of the source OP 313 at very high energies with the LST-1. Although OP 313 was known at lower energies, it had never been detected above 100 GeV, making this the LST-1’s first scientific discovery. With these results, OP 313 becomes the most distant Active Galactic Nuclei (AGN) ever detected by a Cherenkov telescope, further showcasing the LST prototype’s exceptional performance while it is being commissioned on the CTAO-North site on the island of La Palma, Spain.</p>
