Supernova SN 2024gy in the NGC 4216 spiral galaxy: a image – 16 Jan. 2024.

A new, bright supernova is now shining in the spiral galaxy NGC 4216. We observed it last night and are pleased to share our image here.

On 4 Jan. 2024, Koichi Itagaki, one of the most prolific supernova discoverers of our times, has found a new transient in NGC 4216, quickly confirmed to be a type Ia supernova.

The host galaxy, NGC 4216, is a member of the Virgo cluster and it is an almost edge-on spiral galaxy.

The image above comes from the average of 16, 120-second exposures, unfiltered, remotely taken with the ARTEC250+Paramount ME+C3Pro61000EC robotic unit available as part of the Virtual Telescope Project facility in Manciano, Italy. The image was gently processed to show all the finest details and structures visible in the original data.

Together with the supernova and its host galaxy (see the upper left inset), many beautiful cosmic islands are also visible in our image. Below, we labelled the most impressive ones.

We estimated SN 2024gy as bright as mag. 13.2 (unfiltered, R-mags for the reference stars from the Gaia DR2 star catalogue); please note that this is a very preliminary estimate.
