I have caught a super nova! So chuffed about this got it in my image of M74 here are the details...
The spectral signature suggests a Type II supernova, a star that collapsed then exploded when it ran out of fuel in its core. According to observations made some time ago with the Hubble Space Telescope, the progenitor star was a 25th-magnitude red supergiant star, exactly the type of star astronomers expect to detonate as a Type II supernova.
M74, a 10th-magnitude face-on spiral galaxy, is located in the constellation Pisces. This time of year, you need to stay up late or rise early to see Pisces well up in the eastern sky and by about 3 a.m.
