2012fr New Type Ia to Watch in NGC 1365 Fornax;
      #5496856 - 10/30/12 08:43 PM

Edit: It is 2012fr now. This one is low, not too bright yet but is is brightening and should continue to brighten nicely I think. Time will tell. I know for me it is a 1:00 a.m. type of object when the moon is gone. Anyway, it is PSN J03333599-3607377 in NGC 1365 (offers a wonderful image or sketch here). Here is an image by Ivan Curtis. He estimates that estimate the R mag at 14.2 and rising. He also states that "during one hour it brightened in R mag by approximately 25 mmag." Watch this one and if you image or sketch and can catch it with the moon out of the way, it should make for a nice sketch or image if it continues to brighten like it is.

Thanks for the heads up, I will definitely be looking for this one this weekend or when I go to the Deep South Regional Stargaze the following weekend.

I appreciate the heads-up. NGC 1365, coincidentally, is one of the remaining Dunlop 100 objects that I haven't seen and that I wanted to attempt from my home latitude this season. At midnight this new moon it will culminate 12 degrees above the horizon here. Going so low with my equipment will require some special preparation but the SN should be a sufficient inducement!

Thanks for the heads up. I plan on a trek to Kansas next week with great southern horizons, will give it a go.
Is that NGC 7479 in Pegasus for your sig pic? Great galaxy, saw the arms fainty on a near perfect night in August this year.

Hi Jeff. Yes, that is NGC 7479 in my pic. One of my favorite fall galaxies. NGC 1365 is also another wonderful Great Barred Spiral as well. I love the late Scott Mellish's capture of it as found at ASOD.

Wow, that is a fantastic sketch. The latitude, the master, the object. A perfect confluence.

Hi Jay, et al;

Viewed this SN last night under mediocre skies and it was easy in a 16 inch at 150X. There is a nearby foreground star that is about 1.5 magnitudes fainter. I am hoping that by this weekend I will have some decent skies and will report again if I get a peek.

See ya;

On November 6.59 UT, I estimated SN2012fr as mag 12.3 (or slightly brighter). This was according to ASAS-3 magnitudes and the SN was slightly fainter than the bright GSC "12.2 mag" star 8' to the NW. ASAS-3 says it is of V=11.7. With my 10-inch telescope in Western Australia I could clearly see the new star with only 50 magnification and was much brighter than the close neighbour star.

In this area I counted some 30 galaxies in the Fornax galaxy cluster and its vicinity. Incidentally, I had a look at NGC1365 with my Canon 18x50 IS binoculars on Oct. 25, just two days before SN2012fr exploded! It was my 5th supernova this year.

Clouds part! Clouds part! Grrrr, we are supposed to have more than 300 clera nights a year, why all the cloudy ones have to happen around new moon and when ther is a supernova easily observable from 34N????

I was sure it would be futile but I gave SN 2012fr a try last night from the ASH Naylor Observatory anyway. The 17" f/15 classical Cassegrain was almost horizontal when I trained it on the location of NGC 1365.

The supernova SN2012fr has brightened to magnitude 11.9 (Nov. 11.59 UT). With my 10-inch Dob, I could discern the long, beautiful spiral arms of NGC1365.

Clouds did partially part. In between clouds, and just above a line of distant thunderstorms lining up on the Lebanese coast 120 miles away full of lightning, I managed to get a glimpse of NGC 1365 and sn2012fr last night. The continuous ligtning was not helpful in allowing any details to be seen in NGC1365, but I could see the SN which appeared brighter than the other superimposed stars on the galaxy. If weather allows we will have another go on Thursday or Friday..

Hi Timo, I guess that was not from Sweden, right???

It seems the weather has decided not to allow me to have a good look at this supernova. I had three attempts. My first attempt a week ago was foiled by continuous high clouds blocking all the south horizon. My second attempt on Wednesday evening was by far the most succesful. Excellent transparency, highest ever SQM reading for the given location at 21.11, but I was only with my 4" refractor. Still, managed some details. last attempt on Thursday evening, again partially foiled by thin cirrus clouds. The view through my 18" was not significantly different than the previous evening's view through 4 inches! Hopefully I will manage another attempt tomorrow evening, otherwise I will have to wait until December!

Any news on this SN? With the moon getting out of the way it's again becoming available. Has anyone observed it lately? Anybody from the southern areas?

Last view was on November 18th with a 24-inch f/3.7 from the Southern Tablelands in New South Wales. Still seemed 12th magnitude at that time and pretty impressive -- both the supernova and the galaxy ;-)

Good to know! Hopefully I'll get a chance with this week, provided weather cooperates...

Nice place to keep a 24" at, Steve
