Check out this new paper, "Photometry of Type II #Supernova SN #2023ixf with a Worldwide #CitizenScience Network" https://iopscience.iop.org/article/10.3847/2515-5172/ace41f

I was a co-author, so I guess I can no longer claim that "I'm not an astronomer"... 😀

The AAVSO light curve of #supernova #2023ixf to date shows the fireball continuing to redden (i.e., it's getting fainter at blue wavelengths more quickly than in the red). There's still some subtype uncertainty; how this proceeds will determine if it's a IIP or a IIL. #astronomy

Capturing Supernova SN 2023ixf in M 101 with a backyard telescope

Dr. John Barentine FRASJun 7, 2023

A gorgeous new image of Messier 101 (aka the 'Pinwheel #Galaxy') taken with the Gemini North 8-meter telescope was released today by #NOIRLab to mark completion of the repair and refurbishment of its primary mirror.

The bright blue star at left with the rays coming off it is supernova #2023ixf, a massive star at the end of life that blew itself up last month. It's still visible in small telescopes.

Astronomers Telegram #16050: likely progenitor of SN #2023ixf found in archival HST data; "we obtain an approximate absolute magnitude (no extinction correction) of -4.66, which is in line with a supergiant progenitor."

Tracked down #Supernova #2023ixf in M101 (the Pinwheel galaxy, just off the great bear’s tail)

A bright pinprick, about mag 12 - not bad for something 21 million light years away🤩

My friend Scott Tucker, of Starizona here in Tucson, made the front page of spaceweather.com today with his excellent image of M101 and SN #2023ixf. The image was taken on Saturday, 20th May, when the brightness of the supernova was still rapidly rising.

Observed SN #2023ixf tonight for the second night in a row. Last night I had it visually at magnitude +12.2; tonight it is considerably brighter at an estimated +11.1.

AAVSO finder chart for the field of #supernova #2023ixf in #M101, plotted with a 1º field of view and a limiting magnitude of 14. Comparison star magnitudes are shown without decimal points, so, e.g., "119" = magnitude +11.9.
