Ngc 5587 possible super nova?

[mdstuart]

So I have just come in from observing a load of galaxies...and I observed NGC 5587 in Bootes at 11.45pm.

A lovely low surface brightness slither.

Now on the NW tip (the side away from the bright field star) was a mag 14 ish star but there is no star on images or my maps so maybe a supernova?

Please can some one image it for me to see if there is a sn evident?

Thanks

There is a star right on the edge of this galaxy,to the right of the brighter star that is just above the centre of the galaxy.

Sorry, meant to add - standard orientation, North down, East to the right.

AND... another thing. You say that this is the side 'away from the bright field star'. The star visible on the E side of the galaxy on the PSS image above is mag 16.0. Was your star 2 magnitudes brighter than this? If so, I guess it might well be a supernova.

To me, the image seems to show a star considerably brighter than 16.0, but that's the magnitude given for the star by the AAVSO. The star's identifier is 4UC520-056155.

Cheers,

Won't be there if Mark's actually discovered it.

That was my point.

Thanks guys. It was about mag 14...not to the edge but at the end of the galaxy halo.....I definitely would not see mag 16....I will recheck tonight hopefully....now if I had any credit left on itelescope......

Hope you are right,it would be amazing to find a nova.

Update..had another look at this last night. It is definitely brighter on one end visually. Remember I can only see the brightest parts of the core and halo. I can see its a patch of brightness rather than a point source now, it looks a bit like a HIII region..

I found this which I think shows an off centre core which might explain what I am seeing.

Go on big dobbers..have a look and tell me what you think.
