Supernova SN 2021sgz in IC 3095 galaxy: a image – 9 July 2021.
We observed the supernova SN 2021sgz in the IC 3095 galaxy, as part of our supernova follow-up program: here it is our image.
The image above comes from the average of five, 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. At the imaging time, the target was low (about 25 deg.) above the horizon.
The host galaxy is IC 3095. As for the supernova, we estimated SN 2021sgz as bright as mag. 16.4 (unfiltered, R-mags for the reference stars from the Gaia DR2 star catalogue). This transient was discovered on 6 July 2021 by ATLAS survey and it is a type Ia supernova. On the bottom, the bright star HIP 59847 is visible.
