Potential Supernova 2020ue in NGC4636

#1

Post by ARock »


They say it is at Mag 12.8 now. There seems to be a good separation from galaxy, so might be easier to pick out.

Still out of range in visual for me, but in range to image with the 80mm frac. From my balcony the best time would be around 5 am :shock:

Good find AR, this one should be within someone's range visually. Though again in the early morning hours since it is in Virgo. The galaxy and SN are both bright, so many folks should have a chance at this one as long as they don't mind getting out of bed for it! :)

The CN post seems to be indicate it will get brighter. Who knows?
But if you try to see a Mag 13 DSO in the early hours of the morning, make sure your cursing does not wake the whole neighborhood up :lol:

Good time to do an observation in Virgo in the early AM. Last month just before sunrise I was scouring the area between Vindemiatrix (Virgo) and Denebola (Leo) and picked up the Virgo cluster (as I have done many times) With a 2 degree field of view in low power in my 6" scope I counted numerous hazy blobs, in fact a few of them overlapped.

Yea I know... My 8dob is just not an adequate tool from my site... I tried it out two nights ago to see what mag. star I can see max. Turned out at 12.6 I already have to use averted vision... and the night was pretty good. And that was a single dot of light. How am I going to try to pick out a 12.8 dot in the haze of a galaxy? At least this last sn gives me hope cuz it is not in the galaxy halo. If it could just brighten 2-3 tens of mag. and I could have a decent sky too... in this season, so many ifs are like a conjunction of Jupiter and Saturn. :D

I'm gonna have a go at it during tonight's dark period (actually early Monday morning). I think.

Supposed to be clear, but as usual, it looks like we'll have our terrible transparency and crap seeing conditions.

But, if your sky is always a pig sty, might as well be a pig. :lol:

Check your references: http://www.rochesterastronomy.org/supernova.html#2020ue

But if your stellar limit with an 8" is only 12.6, then would be a struggle.

Yea the rochester site but it does not put any updates on any of the sn! Frustrating...
And yea I know it will be a tough nut to crack but it will be doable and the first sn I actually have the chamce to see clearly! I haveone more logged but that was last year, the one so close to the core that I used up all my imagination not to come back empty handed... this time it's different!

P.s. guys, can u not do anything for the login to work again? On my phone I cannot log back, the link at the beginning of the forum is no good for the phone and I have had to sign in here from all kinds of foreign devices, so frustrating...

The only estimate for SN2020ue that I've found is a projection of reaching mag 12.1 at its peak. However, you cannot take that as a certainty, but it does bear watching. The difficult task there is identifying which star it is in the field. It forms a sort of "X" pattern with four other foreground stars and is the brightest of the bunch. However, those four stars range from mag 15 to 17 so should not even be visible for you. The bright star south of the galaxy is mag 8.0 HD 110514. The image is courtesy of the British Astronomical Association web site. Hope that helps.

Milan, for your phone, see this: https://www.theskysearchers.com/viewtop ... 776#p54776

This issue is fixed, you just need to clear your cookies/cache.

This SN is fairly easy to pick out. I scored it this morning. Go for it.

Nah, that one eluded me. I think a combination of core proximity, out of practice, and getting way too chilled to properly concentrate. Oi indeed! :lol:

I'll get a report worked up here in a bit. :)

Well, typical. I did everything with my phone that the link said, Bryan, still it says "invalid blahblah", I cannot access the site from my phone. It is scientifically because every electrical gadget hates me. It is a proven fact. Everyone can do it, but I am always special.

Thanks for the encouragement and info Alan, I hope to catch my first real sn on qThursday night when forecast says it will finally clear. I hope!! Fingers crossed!!

Why thank you, Bryan, I love u guys too. In a platonic way... like a good book... or the beach... or a good book...🤪😂

One important question, Bryan... and others, why not.? Did you not see the other sn because it cannot be seen or because you were not trying hard? Do I have a shot with my 8dob and well-advertised home conditions? Because if not, I would not like to waste time with it at 4am, would just go back to sleep after the first sn. Tomorrow it says clear sky, I am so excited for my first sn!!

Re: Potential Supernova 2020ue in NGC4636

Looks like SN2020ue is listed at mag 12.1 now so that should help out a lot of folks.

Milan, the biggest issue with SN2020oi (which has now dropped to 13.6) is its proximity to the core of M100. It is only about 4" north of the core. Because of the brightness of the core it can be difficult to resolve them visually. Look at the image above, that gives you some sense of what I am talking about.
