Supernova in NGC6824 (Cygnus) AT2017glx

[alanjgreen]

Heads-up for a new supernova found on 3rd Sept = AT2017glx (mag. 14.5)

See http://www.rochesterastronomy.org/supernova.html?#2017glx

Its well placed overhead in Cygnus.

 

 

I can also see SN 2017gkk in the list. Its in NGC2748 (located over near Polaris) and shows as mag. 14.7

Happy hunting,

Interesting, but both will have to brighten to be within range of my scope. I see from my notes I haven't bagged NGC 6824 either (which is in range of the scope), so that would be a great option, should the SN brighten further

[michael.h.f.wilkinson]

Just did a back-of-the-envelope calculation, and as it is now classified as a Type 1a supernova, the distance of around 50 Mpc suggests a peak magnitude of about 14, without allowing for extinction by dust. 14.5 may well be its peak, alas

Finally had a crack at this SN last night with the 20".

The galaxy was an easy find - small and bright.

I was not able to separate the SN from the galaxy core (as it is close in) but I am certain that it was the SN that was making the galaxy so luminous.

Hope to get another chance next week...
