Supernova SN 2011b in NGC 2655

Recommended Posts

This is a relatively bright supernova (mag. 14) discovered in January in a very accessible galaxy, as it is circumpolar.

Here are shots from the 3 Feb, in colour, fairly wide field taken with a 10" Newtonian, and 8 Feb, in monochrome, close-up with a C-11, longer exposure. Though in the first image the object appears to be outside the galaxy, the longer exposure shows it to be within the spiral arms. In the close-up image, though collimation looks to be a bit off, the galaxy shows interesting structure, with a dark swirl emanating from below the nucleus. The spiral arms go out to at least 3 times the nucleus–SN distance.

David a good astro photo showing this supernova in early February. I tried to view it last Saturday but could no longer see it with the 10" even from my darkish site.

It would be interesting to get a current photo and magnitude position.

Thanks David - that is why I could not see it anymore. Glad I observed it in January.
