Supernova SN 2021J in NGC 4414 galaxy: an image – 11 Feb. 2021

We observed the bright supernova SN 2021J in the spiral galaxy NGC 4414, as part of our supernova follow-up program: here it is our image.

Supernova SN 2021J in NGC 4414 galaxy: 11 Feb. 2021.

The image above comes from the average of five, 120-seconds 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 4414 and it’s placed at about 60 millions of light years from us. As for the supernova, we estimated SN 2021J as bright as mag. 13.1 (unfiltered, R-mags for the reference stars from the Gaia DR2 star catalogue). This transient was discovered on 1 Jan. 2021 by the Zwicky Transient Facility (ZTF) survey and it is a type Ia supernova. As you can see, there are many galaxies in the same field of view.

Further observations will follow, weather permitting.
