Supernova in NGC 7814 (Pegasus)

#1

Post by kt4hx »


If you can wait until after midnight when Pegasus is starting to climb a little bit, the Type Ia supernova 2021rhu is currently listed at magnitude 12.5 in the bright galaxy NGC 7814 (mag=10.6, size=5.5'x2.3', SBr=13.2). This galaxy lies in the southeastern quadrant of the "Great Square" asterism that forms the body of the mythical flying horse. The SN is positioned 6" northeast of the galaxy core on the other side of the dust lane. Good luck and hope some of you can get a shot at it. :)

Here is an image of the SN courtesy of Carlos Segarra via https://www.rochesterastronomy.org/supe ... ml#2021rhu

I did not capture this Greg. I never have and never will do imaging - not my game. I stated the image was courtesy of Carlos Segarra through the linked website. So the image is totally his work. I only included it to illustrate the position of the SN relative to the galaxy core.

My notes from the night of July 9th says, "Core appears to be double."
Now I know why. Thanks!

Thanks for the heads up Alan.

The SN is clearly brighter than the whole core. Awesome!
