NGC 5154 and supernova SN 2020bcq: a image – 25 Mar. 2020
We captured supernova SN 2020bcq and its host galaxy NGC 5154, as part of our supernova follow-up program, with a number of other galaxies all around. Here it is our image.
The image above comes from the average of nine, 300-seconds exposures, unfiltered, remotely taken with “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. SN 2020bcq is indicated by an arrow in the upper left insert.
We estimated SN 2020bcq as bright as mag. 18.3 (unfiltered, R-mags for the reference stars from the Gaia DR1 star catalogue). This transient was discovered on 27 Jan. 2020 by the Zwicky Transient Facility (ZTF) group and it is a type Ib supernova. The host spiral galaxy, NGC 5154, is placed at about 250 millions of light years from us; in the same field of view, there is NGC 5149, a barred spiral galaxy: the pair was discovered by William Herschel on May 1, 1785.
There are more galaxies all around, visible as fuzzy spots of light, more or less evident.
Further observations ill follow, weather permitting.
