A Couple of Recent Supernovae - SN2022ewj and SN2022eyj

[Bill S]

Over the past couple of clear nights I had a look at a few supernovae. Two recent ones are shown here.

The first is SN2022ewj in NGC 3367. The galaxy is an SB(rs)c 113 Mly away. The supernova is magnitude 15.9 and is a Type II (i.e. core collapse) discovered on 19th March. The misty background in the snapshot is due to clouds that were passing over.

 

The second one is SN2022eyj in UGC6312 in Leo. The galaxy is a spiral type SA at a distance of about 293 Mly (I think). The supernova has a magnitude of about 16 and is a Type Ia i.e. a binary system where material has accreted onto a white dwarf and reached the Chandrasekhar mass and exploded. It was discovered on 22nd March.

 

There's always summat!

Nice work Bill. I hope these are still around when I next get to my scope in a few week's time.

NGC 3367 is a beautiful galaxy in its own right -- good old supernova leading you there!
