Supernova SN 2021bug in NGC 4533 galaxy: an image – 16 Feb. 2021
We observed supernova SN 2021bug in the galaxy NGC 4533, 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 is the spiral galaxy NGC 4533. As for the supernova, we estimated SN 2021bug as bright as mag. 17.7 (unfiltered, R-mags for the reference stars from the Gaia DR2 star catalogue). This transient was discovered on 04 Feb. 2021 by the Zwicky Transient Facility (ZTF) survey and it is a type II supernova.
As you can see, there are many galaxies in the same field of view: among them, we see the the superb NGC 4536 on the right, an intermediate spiral galaxy. Gérard de Vaucouleurs considered NGC 4533 and NGC 4536 a couple of galaxies.
Further observations will follow, weather permitting.
