Description

A type II Supernova was discovered on April 11, 2024, by ATLAS in NGC3621. The new transient was mag. 18.915 at the discovery, but it’s rapidly rising. I took this picture last April 15 from a Chilean remote telescope, measuring a mag. 12 (confirmed by Pan-STARRS Group photometry on April 16).Today it’s the brightest SN discovered this year and the closest to Earth since SN 2023ixf, discovered on May 19, 2023.NGC 3621 is a field spiral galaxy located at a distance of approximately 22 million light-years (6.7 Mpc) in the equatorial constellation of Hydra. It is relatively bright and can be well observed with moderate-sized telescopes. The galaxy has a diameter of about 93,000 light-years (29,000 pc) and is inclined at an angle of 25° relative to the edge-on view.The morphological classification of NGC 3621 is SA(s)d, which indicates that it is an ordinary spiral galaxy with loosely wound arms. There is no evidence of a central bulge.Detailed information and updates can be found at Latest Supernovae (rochesterastronomy.org).
