Supernova SN 2021biz in NGC 4227 galaxy: an image – 11 Feb. 2021
We observed supernova SN 2021biz in the lenticular galaxy NGC 4227, as part of our supernova follow-up program: here it is our image.
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 lenticular galaxy is NGC 4227, placed at about 300 millions of light years from us. As for the supernova, we estimated SN 2021biz as bright as mag. 15.3 (unfiltered, R-mags for the reference stars from the Gaia DR2 star catalogue). This transient was discovered on 29 Jan. 2021 by the ATLAS survey and it is a type Ia supernova. As you cansee, there are many galaxies in the same field of view.
Further observations will follow, weather permitting.
