M66 Supernova

[PeterM]

Discovered last night by ASASSN - a young type 2 SN at mag 16.7 that will brighten, possibly to mag 13 ish.
Greg Bock from Boss was able to confirm the SN last night.
Color images encouraged to be sent the Bright Supernova page.

Very nice and well done :)

Thanks for the alert Peter! And to think I so nearly started an imaging run on these after dusk when they were higher in the sky. Canned another target when I saw your alert :)

It's still pretty faint, I'd estimate 16.8 or 16.9 off my image with comparison stars on skymap.org, though seeing was pretty poor and it was getting pretty low in the sky.

Here it is, 12 x 5 minutes, 200mm f/5 Newtonian, EOS 60D at ISO800. I'll send it in to David Bishop too. Darks, flats & bias subtracted, processed PixInsight. First image is 150% scale.

HI all,
FWIW, this is the confirmation image taken for the ASAS-SN team at the time of their alert..only 10 x 30 second images, Meade 14F7 LX200R, SX Trius 694 binned 2x2. Estimated magnitude then was 16.7v.

Congrats Greg and the team :thumbsup:

Here's my attempt last night...had a couple of technical issues that prevented me from catching it earlier in the evening :mad2:

C8 EdgeHD at f/10, Canon 6D.

Looks pretty bright to me :D

An image from 30th May, the SN appeared to have brightened slightly from my image of 24 hours previously; however the 30th May had both better seeing and the SN was a bit higher in the sky. From comparing last night and tonight, there appears little change in brightness (maybe just a wee bit brighter, ~0.1mag?), though I'd revise my estimate of brightness to nearer mag 16.6 with the sharper view.

Also an animation with an M66 image from last year taken with my old scope, the improvement in resolution from 150mm to 200mm is significant!

The weather (http://www.bom.gov.au/nsw/forecasts/sydney.shtml) probably ensures this will be my last M66 image for a while...

[Greg Bock]

Looks good Andy, weather here is bad now, and will be for days, so no imaging here for a while either..

Gees, I hope Peter is right about the SN brightening to mag 13. If the clouds co-operate we'll see it in the 14" for sure. It'll stick out like the proverbial in fact!

Again, great shot Dunk.

Cheers all!

Very difficult to catch this visually last night. The three stars outboard of the galaxy to the left of the supernova are easy enough in a 25", but the supernova is hiding amongst a few bright HII regions in the spiral arm. Although I knew exactly where to look and managed to snag it at about 250x, there's no way I would have picked this up with a visual search.
cheers,
Andrew.

Congratulations to Greg for another discovery.

I got about an hour's worth of luminance of this SN tonight and added it to my previous HaLRGB image.

This is an iPhone shot of the SN from last night. Not too sure but I think I got it. I'm keen to have another go if it brightens. :D

[alocky]

nice one Barry - definitely got it.

[sn1987a]

Thanks Andrew. I'm thinking I might try again Sunday night if the weather gods allow. :D

[Greg Bock]

Absolutely sensational image there Martin. The detail along the arms is amazing.

Yes, it was a good find in such a close and bright galaxy, I'm very lucky to be associated with the ASAS-SN team through the Ohio State University, and of course independantly, the guys on the BOSS team here and in NZ.

[CAAD9]

We've been cursed with dreadful weather here in Brissie. Does anyone know if the SN is brighter than on the weekend? Or has it dimmed? Is it worth trying to go to a dark spot, say on Wednesday to try to catch it?

Thanks all.

Second Greg's comment. Sensational shot Martin!

[sn1987a]

I could see it a lot easier last night in my 28. Seems to be brighter here's an iPhone shot from last night.

[CAAD9]

Thanks for the reply Barry.

Am I to understand that the SN is the fuzzy patch above the galactic nucleus at about 10:30 position?

I'm going to attempt seeing it in a 14". It's the best I got!

[sn1987a]

This one ( I could be wrong wouldn't be the first time :P )

[CAAD9]

Thanks Barry.

Brother in Law & I went out to our normal "dark" sky sight. I couldn't see it,:shrug: albeit I did enjoy taking the time to observe m66 more closely than what I have before.

I could see some of the spiral structure and a bit of the central region as a semi circle. I found the view through a 9mm EP the best combination of dark background and at 183x, magnification.

Alas in between the clouds, people driving into the lookout and the encroaching LP of Ipswich I couldn't see it. The BiL cought a glimpse of something at about the 10 o'clock position relative to the core as viewed in a reflector, i.e. Opposite the row of three foreground stars. So the right general area. But that could also be one of the bright star forming HII regions... Who knows ?

As disappointed as I was with the whole outing last night, observing is still better than not observing:thumbsup:

Fantastic picture Martin. What did you capture the pic with?
