Abstract

We confirm the reported discovery of AT2024ggi in NGC 3621 (AstroNote 2024-100) with GOTO as part of our all-sky survey, detected at L = 16.83 +/- 0.02 (2024-04-11T10:51:22). Data taken 24h prior (2024-04-10T10:56:25) do not detect AT2024ggi down to L = 19.46, with the ATLAS discovery occurring just 16h after this limit, further underscoring the remarkably infant nature of this nearby (7 Mpc) transient. Intensive spectroscopic and multi-wavelength follow-up are strongly encouraged.
