SN 2014as (PSN J14005449+4058596)

Follow up image on Supernova PSN J14005449+4058596 discovered by Dave Grennan in Raheny a hour or two earlier. Dave was conducting his supernova hunt the other night and mentioned that he might have something interesting in a facebook post. After hearing what it was I rushed up to my observatory to try and get follow up images. I got the first image at 00:18 UT. Then followed a nervous hour or more waiting to see if the there would be a discovery announcement, but there wasn't so it looks like this will be Dave's 3rd supernova discovery! I can probably claim to be the second person on the planet to see it though Since then it's been confirmed as a broad spectrum Type1c supernova by an observatory in China who got a spectrum of the star. A Type 1c supernova is what you get when a massive star that has blown away all its outer hydrogen and helium gravitationally collapses in on itself as the nuclear fusion at the core has stopped. The resulting explosion can easily outshine other stars in the galaxy. Galaxies are estimated to have one supernova on average every 50-100 years.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
