Great image John - all I need is a clear sky

Ten days ago a SN found in nearby NGC 3448 - see chart - it's amazing to think its light passed by M82 some 12M years ago and light from both events arrived on earth at nearly the same time after all those eons

There's an amazing picture on Twitter from someone who was able to capture an image with a 66mm refractor:

I imaged this on the 19th and didn't even notice, thought it was a milky way star!

Wow! I observed this SN at 8:30pm on Sunday night 1-19-2014 at a green dark site. I did not recall a star there on M82 and had a fellow observer take a look. He texted me later that night and said it was a field star. Very cool!

Correct me if I'm wrong but is this possibly the closest SN since 1987A?

Not that Wikipedia is always correct, but this article states that it's the closest SN since 1993J.

It's about 6 degrees and windy out, with 6" of snow on the ground. But I was able to sneak in a quick glimpse between the clouds, easily spotted with my 10" f/5 despite some light pollution reflecting off the snow. I'm very glad to see a such a rare event, especially now that I'm warm again!

With the memory of SN 2011fe not so far away, I decided to do a few brief, rough calculations to approximate the M82 supernova's peak brightness. Both of these are white dwarf (Type 1a) supernovae, meaning they each will have the same peak luminosity. This however is different than apparent brightness, which is not difficult to calculate if the distances are known.

In short, I predict a peak brightness of magnitude 8.7, not taking into account any dust absorption. Attached are my calculations.

Very nice! I'm inside warming up while I work on imaging it (even as I type). Hopefully I can get something nearly as nice as your "quickie".

Wow that's the brightest SN I recall seeing. Thanks for posting, Achim.

Showed it to my daughter in my 18-inch tonight--very nice--usually it's kind of hard to tell someone where to look to see the SN; this time it was easy!

I just checked it out with my 8" reflector. I found both M81 & M82 as faint fuzzies. The SN is was not visible to me. I'm in a Red zone near an Orange zone border but viewing North means viewing over the brighter part of town. If the brightness is supposed to peak this weekend I will continue to try.

What about SN 2004dj in NGC 2403? That galaxy is 8 to 10.5 Mly distant according some sources.

Regarding possible maximum magnitude, I've calculated magnitude 8.4 assuming it is not obscured. I used -19.3 absolute magnitude and 11.5 Mly distance.

The Latest Supernovae site is listing now magnitude 10.9! Unfortunately bad weather here...

Hi,

the official name for this supernova is now SN 2014J.

I only read about this supernova as I was about to go to bed last night for an early start this morning. Funnily enough, I'd been using a 12" Newtonian to view galaxies that evening, including M108 and M109 in Ursa Major, but not M82 unfortunately!

So, I delayed my sleep to view SN 2014J with my old 8" SCT (for ease of set up). It was only a quick look, and I was not very dark-adapted, but it was quite easily visible - though more so with averted vision.

Due to lack of time I did no imaging, but I've got my fingers crossed that there will be some clear skies on Saturday night as predicted. Generally the weather has been unsettled and mostly cloudy.

Regards,

Delighted by the maximum estimates above. Of course in a highly inclined spiral like M82 it is likely to be obscured, but on the other hand since it is in a star cloud (as visible from Earth) it is at least between the densest of the dust clouds.

I have just come in from a short session, chasing the supernova through some sucker holes in the clouds. It was very clear between the clouds and the supernova was easily visible in my 63mm Zeiss Telemator at 76x (11mm ES82) and 93x (9mm ES100). It was difficult at 47x (18mm ES82) and not visible on the bright background of M82 at 28x (30mm ES82).

At 93x, I could hold it steady, along with some clumps and dust bands in M82. A fantastic sight! At 28x, in the 3° TFOV of the 30mm ES82, I could see the huge disk of M81, which appeared bigger than normal, and also keep both NGC 3077 and NGC 2976 inside the field. A wonderful view.


Clear skies!

Very cool! Can't wait for a break in the clouds! And maybe a change in the weather ...
