M100 - new supernova

[kt4hx]

For those that are up to the wee hours of the morning, there is a new SN in the galaxy M100 (NGC 4321) in Coma. Its designation is SN2020oi and it is 4" north of the galaxy center. I am away from home and optics so this one will escape me, but hopefully someone will give it a shot, particularly you imagers! Discovery mag is listed at 17.3 and it is presently listed at mag 14.6 and should continue to brighten (hopefully). Some links for you below

Thanks for the heads-up Alan. Unfortunately I don't believe it will be visible in the Z10 from home. I hope one of our resident imagers captures it, as you say. I'm still waiting for Betelgeuse.

I'm still waiting for Betelgeuse.

It would be nice, but not in our lifetime buddy!

Thanks for the heads-up Alan, though I won't see it from here or a dark site with a 10" Hope the imager-types get a shot off.

All the best,

Thanks for the heads up Alan. If it drops mag by another unit I will give it a shot.

Thanks for the notification. I've been trying to get an image of all supernovas in Messier objects since I started imaging. I have six since 2011. I think I missed one due to weather. So I'll give it a try if we get some clear skies.

Thanks for the heads up, Alan!
I am always up for a challenge if it were to brighten a tad bit more, but weather here is crap right now and I don't see anything saying "clear" at night in the 10 day forecast. Someone nearby must have ordered some new equipment!

No wonder my forecast is grim. This is an astronomical EVENT. Even Veiled Everywhere, Not Tonight.

I'll keep an eye out though. The Veiling has a knack for unveiling when you least expect it.

Well as Milan stated in the other thread, Rochester now shows it up to mag 13.2, so its certainly visible - clear skies needed of course! Also if you can separate it from core.

Will it still brighten or just fade from now on? The Moon is very near it, and brightening to a bit less than 13mag would also help my 8dob. Cuz of the late hour show, I will only go out once for it. Should it be asap or should I wait a few days?

And how much is the separation from the core? Less than 2"? I will never be able to separate it if it is so. Is it too much to ask for a sn of 11 mag in say Andromeda, wit h a srparation of 6"?

How is your forecast? If you can, I'd let the Moon clear out of the way first, at least by one evening if your forecast will support the wait.

We don't know with absolute certainty how quickly this type 1c will decline. As I stated in the first post it is separated from the core by 4", and as you can see by the linked image there, it is a tight pairing. So agree with Bryan that you should allow the moon to get out of the way. Unfortunately we don't know if in the time it takes for that to occur, the thing will peak and begin its decline. As you well know, SNe observing is a bit of a crap shoot! Good luck, I wish I were at home where I could take a shot at it.

Thanks for the info. I'm always up for a new adventure.

Well forecast says clear but it's so darn foggy like a soup. Guess I will have to wait and that is that. Maybe it will be good and it will brighten and the moon will take a hike as well.

Thanks, Alan... I hope I can actually see something of it. Why, where are you now, by the way?

I am somewhere far, far away, deep inside of a bright city. While I can see stars of at least 3rd magnitude without the moon present, it is not a good place to be with small aperture! So it will not be an observing trip by any means. Not all of them are.

[milanpicard]

Hey guys, what magnitude is the sn now, does anyone know? I cannot believe the Rochester figure, that has been listing it 13.2 for a week now!

P.s. Alan kindly told me what do do if I cannot log in, and now it is up on the forum too... but I usually log in from my phone and that has no windows or google chrome, but some android... I just go to the internet icon and that's that. What operating system is that? What do I do to be able to log on from my phone? I am writing from my laptop now, which can log in ok but I seldom use the laptop...
