Supernova SN 2021egh in NGC 3016 galaxy: 10 Mar. 2021.

The image above comes from the average of seven, 120-second exposures, unfiltered, remotely taken with the “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available as part of the Virtual Telescope Project. The supernova is indicated by an arrow in the upper left inset.

The host spiral galaxy is NGC 3016, likely placed at about 450 millions of light years from us. As for the supernova, we estimated SN 2021egh as bright as mag. 18.7 (unfiltered, R-mags for the reference stars from the Gaia DR2 star catalogue). This transient was discovered on 3 Mar. 2021 by the and it is a type II supernova.

Moving upper-right from the transient, the barred spiral galaxy NGC 3020 is also visible.
