Supernova SN 2021bms in CGCG 539-105 galaxy: an image – 03 Mar. 2021

We observed supernova SN 2021bms in the galaxy CGCG 539-105, as part of our supernova follow-up program: here it is our image.

Supernova SN 2021bms in CGCG 539-105 galaxy: 03 Mar. 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 galaxy is CGCG 539-105. As for the supernova, we estimated SN 2021bmx as bright as mag. 17.5 (unfiltered, R-mags for the reference stars from the Gaia DR2 star catalogue). This transient was discovered on 31 Jan. 2021 by the ATLAS  survey and it is a type Ia supernova.

Further observations will follow, weather permitting.
