Description

Located in Coma Berenices NGC 4559/C36 is an intermediate spiral galaxy. It was discovered by William Herschel in 1785. The distance according to NASA is 30 MLY. From Wikipedia: "The luminous blue variable AT2016blu in NGC 4559 experiences repeated supernova-like outbursts. First observed in January 2012, it burst out again in 2014, 2016, 2017, 2018, 2019, 2020 and 2021". From my sessions in 2017 and 2023 I did not see any difference in that grouping. It seems to  have the same luminosity. See revision B.
