    Default New SN alert - SN 2018ivc in Messier 77



    Just a heads up of a new supernova recently found in the galaxy Messier 77 in Cetus. Currently listed as a Type-II at magnitude 13.6. I intend to target this object Wednesday night when I am out. I encourage others to give it a shot when they can.

    Cool Alan. I'll give it a go with the 18" when it is clear - it is raining presently and forecast to do so through Saturday, so boo.

    Good luck Michael - when you get the chance. FYI, it is positioned about 18" NNE of the galaxy's core. So given that M77 is a Seyfert galaxy with a bright stellar core, I expect that it should give the appearance of an uneven double star.

    Looking forward to seeing if you bag this one IN M77 that is a nice thing to look for.

    Thanks Alan. That ought to drag the clouds in hard.

    I almost set the dob out tonight but I keep getting waves of murky stuff floating through. I'll keep an eye on it this evening. 31 days as of today since my last outing.

    I am sitting on this with a 4" APO and if I avert I can see two stellar points, the AGN and either a foreground star or the SN. I am voting for a foreground star. I will put the 12" on it shortly.

    Where are you seeing the other stellar point in relation to the AGN? If you look at it in ST3, you can get a sense of it. But as you will notice, there is a mag 10.8 foreground star about 1.5' ESE of the AGN whereas the SN is about 18" to the NNE of the core. Good luck.

    We are clouded now, but should be clear tomorrow.

    Yeah, it was the 10.8 star I was seeing in the 4". I sat on it with the 12" for about 45 minutes. I saw some things, man.

    I was getting an intermittent point source of light tight in with the AGN, so I remain a bit inconclusive until I can investigate my visual some. I'll be checking ST3.

    While doing that, I had the cam running on the 4", so that may verify my potential sighting.

    EDIT: OK, per some imagery I've looked at (not my own yet), the little intermittent point of light I was catching several times with averted vision matches the position of the SN. Sweet. Man, that sucker is almost Pluto tough. Of course, I was contending with some soupy sky too, and finally a grey finger of doom shut that effort down altogether. But still, yay!
