Supernova fireworks in NGC6946

[Red meteor]

A supernova was discovered in NGC6946 by Patrick Wiggins of Utah, USA at about mag 12.8 on 14 May - he had an image on 12 May when the object was not shown. The Fireworks Galaxy is about 22M light years away and has had several supernovae in the last 100 years. Is that how it gets the name?

The image below is with Lum filter; clouds prevented any colour data.

Captured 14 May 22.32UT (SGP)

SW ED80 on EQ6, guided

Ought to be visible with my 12" dob if it holds it's brightness (and the clouds clear off !)

Very profilic galaxy for SN's

Nicely captured much better than i did 13 years ago

here is one I did back in 2004 with one very poor frame

Thank you Ibbo.

Thanks for sharing your image. It is a nice record of the event. The cameras have moved on in the last 13 years.

Ah yes,  sn2004et.  Another type II, around the same magnitude. I was imaging with a modified video camera back then and just starting to do spectroscopy. http://www.threehillsobservatory.co.uk/astro/spectra_8.htm

Tonight I am collecting photons from this latest one for a spectrum using considerably more sophisticated (and more expensive !) kit

Thanks Robin. It was your post on the BAA forum alerted me to the supernova.
