Stu mag12 supernova

Hot off the press and writing on iphone while eating in Hungry Jacks. Stu from BOSS has discovered the teams brightest possible SN todate at mag 12.8 in NGC1404. More later, visual obs and images encouraged. Congrats Stu and he will post image.

Wow! Will go and setup the scope and have look.

Congratulations to Stu and the BOSS team.

Just taken several images and this is bright. The PSN is close to the galaxy and my image here is a 2 second image.
This galaxy is in Fornax and is about 50 million light years away. It had a mag 14.2 Supernova (SN 2007on) that was a type 1a and was extensively studied.
Interesting reading below.

I think this may get a lot of professional and amateur attention.

Just came in from observing the the Supernova, it is quite bright and plainly seen with a 6mm Radian in the 16" scope .
The seeing is quite poor with the first quarter Moon and High thin cloud,but the Supernova was still prominent
I hope the cloud stays away till after the Moon goes down so I can get a better observation
Cheers

Well, I was on it. Unfortunately the seeing was the worst I have ever experienced, so this is a really wooly image. The galaxy has quite a bright, condensed nucleus, and the SN is close by. But the SN is BRIGHT!

Cheers Stu and the B.O.S.S. team.

Sure is bright Ivan!

Well done Stu and the BOSS team

here's my set tonight, pretty bad seeing...and focus was bumped
near the start of the set.

Congrats Stu, wish I was there to help out. Mag 12.8 is awesome, this must be a big one, will be interesting to see the spectrum for it, will be almost bright enough to see through the clouds above Paris!!

Wish I could image this one.

Now that is interesting...............
Bang in the middle of the Fornax Cluster of galaxies, in a field which is notable for the lack of any significant number of supergiant stars. (these galaxies are "red and dead", and have very low Current star formation rates)

Accessing my "memory banks", I seem to recall that NGC1404 is arguably an S0 galaxy rather than an elliptical......in other words, there is a subtle zone outside of the spheroidal component in which the surface brightness falls off more slowly than it does in the spheroidal (bulge) component.

Quiescent S0 galaxies like this one have few or no supergiant stars, so core-collapse SNe are rare or non-existent in them, but there are a few of these "old stellar population galaxies" which for some reason get multiple type 1a supernovae.

cheers, bad galaxy man

As you can see from this UV exposure from GALEX, this galaxy (circled) is nearly invisible because it lacks young stars. In contrast,
NGC 1427A at left is vigorously forming stars and lights up "like a candle" in the ultraviolet:

At 12 mag we should be able to get some interesting spectra using the Star Analyser grating....who's going to be first???

Better seeing tonight, can actually see that it is an elliptical galaxy. I played with the curves, and there is a faint halo surrounding it, so I think madbadgalxyman is right about the galaxy type.

Interesting SN in an interesting galaxy.

Very nice Ivan. yep I think the seeing was a little better tonight but
I battled with gully breezes down here south of Adelaide.

I even got a bullseye satellite right through 1365

Great images Ivan and Steve. I feel a bit left out right now away so far from my scope.
Stu told me yesterday that NGC1404 isn't even on his list, it just happened to be in his field of view when he was actually imaging NGC1399...that's why his discovery image is centred on NGC1399. How lucky is that ?

HI guys,
I thought that I'd take the opportunity to highlight the benefits of working as a team here.
Both Pat Pearl and myself have been in France and the UK for work since the 1st of December, so we are basically out of the loop to discover or assist in the process of confirmation and reporting due to time difference constraints.
However, that didn't stop other BOSS team members from helping out. Colin used SLOOH to get the confirming image and also draft the report to CBAT to ensure that Stu's discovery efforts paid off. And, he did that with all the usual demands of very young family. So, well done Col, as usual, you went out on a limb to ensure that everything went smoothly.
