New Supernova -- M66 Galaxy

In summary: I had a scope that could produce a pic like thatThanks for the image, but you don't need a scope to see this kind of thing. In fact, this type of SN is usually seen with amateur equipment.

Thanks for the image, but I am a bit confused. According to the Astronomer's Telegram they have already come to the conclusion that it is a type IIP SN even before it has reached peak brightness.
We obtained an optical spectrum (range 350-910 nm) of ASASSN-16fq/SN 2016cok (ATel#9091) on UT May 28.63 2016 with the 2.4-m telescope (+YFOSC) at LiJiang Gaomeigu Station of Yunnan Astronomical Observatories (YNAO). The spectrum is consistent with a type IIP supernova at a few days before the maximum light, showing a blue continuum and prominent P-Cygni features of Balmer lines. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J., 666, 1024) shows that it matches with SN 1999em at t = -3 days from the maximum light. After correcting for a redshift of 0.002 for its host galaxy M66, an expansion velocity of about 9000 km/s can be derived from the absorption minimum of Ha line.

In order to determine the difference between a type IIL and a type IIP SN one has to observe the light after it begins to decline. So how are they able to come to the conclusion that it is a type IIP if the SN has not even reached peak brightness yet? :confused:

the answer is in the quote you posted.
I personally don't know the different in the spectrum between the two types, presumably they do and that is how they have drawn their conclusionDave
 

1. What is a supernova?

A supernova is a powerful and extremely bright explosion that occurs at the end of a star's life. It is one of the largest explosions in the universe and can outshine an entire galaxy for a brief period of time.

2. How is a supernova formed?

A supernova is formed when a massive star runs out of fuel and can no longer support its own weight. This causes the star to collapse in on itself, resulting in a massive explosion.

3. What makes the "New Supernova - M66 Galaxy" unique?

The "New Supernova - M66 Galaxy" is unique because it is the latest supernova to be discovered in the M66 galaxy. It is also classified as a type II supernova, which is caused by the collapse of a massive star.

4. When and where was the "New Supernova - M66 Galaxy" discovered?

The "New Supernova - M66 Galaxy" was discovered on April 24, 2020 by an amateur astronomer in Italy. It was located in the spiral galaxy M66, which is approximately 36 million light years away from Earth.

5. What can we learn from studying the "New Supernova - M66 Galaxy"?

Studying the "New Supernova - M66 Galaxy" can provide valuable insights into the life cycle of massive stars and the process of supernova explosions. It can also help us better understand the formation of galaxies and the distribution of elements in the universe.
