In the galaxy M51 “Whirlpool” appeared an interesting star – AT2019ABN. This is a possible supernova, or “imposter”. The star has already dropped the outer part of the shell, but the nuclear reactions are still burning. It is possible that in a few tens of days its magnitude will increase by 2-4. At the moment, its magnitude in the R-filter is about 16.5m. In principle, it is available for shooting from an aperture of 100 mm or more. I recommend astrophotographers to take pictures of this star – the data may have scientific value, and there is a great chance to photograph a supernova explosion.
