Hello! A unique astronomical phenomenon occurs in the sky: there are three supernovae in one galaxy (NGC 5605). All of them were discovered by ATLAS in January 2022: SN 2022bn (type Ib) on 2022-01-05 https://www.wis-tns.org/object/2022bn , SN 2022ec (type II) on 2022-01-07 https://www.wis-tns.org/object/2022ec and SN 2022pv (type II) on 2022-01-14 https://www.wis-tns.org/object/2022pv . I obtained the photos of this galaxy (in the constellation of Libra) remotely using 0.43-m f/6.8 reflector T32 (of iTelescope.Net) at Siding Spring Observatory, Australia. I attach stacked image (12x180 sec. with luminance filter) with mid time 2022-02-17 16:24 UTC. True, they are all now fainter than 18 magnitudes in brightness, but this can still be seen in photographs with long exposures. ------------ Also I report that I discovered supernova candidate AT 2022bsi https://www.wis-tns.org/object/2022bsi in NGC 5902 galaxy (in the constellation of Bootes), now it's fainter than 19 magnitudes in brightness (but keeps getting brighter): I am attaching my stacked image (5x300 sec.) from photos taken on 2022-02-18 (12:03 UT mid time) remotely at iTelescope T24 (0.61-m f/6.5 reflector of Sierra Remote Observatory at Auberry, California, USA). With best regards, Filipp Romanov (amateur astronomer from Russia, discoverer of 80 variable stars https://filipp-romanov.livejournal.com/27664.html ).
