Congrats to Greg Bock who has discovered his second supernova (last night) bringing the BOSS total to 30 in just on 3 years. Ok its listed as a PSN until a spectra is taken, hopefully that will happen in the next few days.
Roger Groom in WA was able to very quickly supply the confirmation image and I am looking forward to when Roger is ringing us to get a confirmation image for his first Supernova. Onya Roger.
This is a particularly good achievement being the furthest North discovery for the team - far more groups/people searching to the North of us.
It's probably a bit faint at mag15.5(U) but well worth taking follow up images.
Been a long time between drinks for me but this year I have taken over 7000 images and I reckon 2012 will be an absolute SN bonanza for the whole BOSS team. We really have the process down to a fine art now and a 100 target has got to be looking good in the next few years.

Greg and Roger will post images soon I imagine.
Details are as below
PSN J02580760-1021541, CBAT TOCP (http://www.cbat.eps.harvard.edu/unconf/followups/J02580760-1021541.html) discovered 2011/12/27.552
Found in NGC 1154 (http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=NGC+1154&img_stamp=YES&extend=no) at R.A. = 02h58m07s.59, Decl. = -10°21'54".0 (http://www.wikisky.org/?ra=2.968778&de=-10.365027&zoom=10&show_box=1&box_width=50)
Located 1" west and 7" south of the center of NGC 1154 (http://archive.stsci.edu/cgi-bin/dss_search?v=3&r=02+58+07.6&d=-10+21+54.1&h=8.0&w=8.0&f=gif)
Mag 15.5:12/27, Type unknown

HI all,
I thought that I'd post a couple of images for those who may wish to image this possible SN (PSN) too. With luck, a spectrum will prove this one too, and make it my second discovery within 10 weeks after 2011gv in IC4901 on October 19, after more than 10 years of searching.

Thanks to Roger for making his time available last night to get the confirmation image 24 hours after my discovery image was taken.
I imaged the new object on December 27th on 2 separate images, but I only checked them a day later to find that I had two images of the new object only about 1 minute apart , so I knew the object was real, but the next question is "Is it moving?" A 1 minute time difference is unlikely to tell me, but Roger's image taken on the following day, the 28th, showed that the new object was stationary..great news.

Now, all I need is a spectrum to prove it, and I have recent advice that the details and coordinates have been passed on to various people around the world. SALT (in South Africa) won't get at it, but observers in the north likely will, so fingers crossed!

And more breaking news,

I have been advised that spectra have already been obtained of my PSN (now SN) in NGC 1154!

I'm told it looks to be a Type II. At 15.5 mag, this would put it on the brighter end of the Type II luminosity distribution.

So, number 2 in the bag...
Now, I must get back to finding number 3.

Hats off to the BOSS team congrats :bowdown:
Science is really going forward at the moment.

What a fitting post to bring up 3000 posts

Cheers Kev

Greg
Well done again and it's great to see Boss hitting it's straps at a great pace.
You must get that great tingle when you know that you are the only person to have seen that Sn before it's confirmed.

Thanks guys,
yes Allan, a tingle and thrill once I start the usual pre-existence checks that shows that its not recorded anywhere before...then the chase is on to make sure that the report is done asap and lodged with CBAT to make sure no-one else claims it..it's an intense hour or so while we do those checks and determine the location and magnitude.
Then of course, The Wait...until we get it confirmed...that's the most nervous part, and can take days...did we really get a SN?, or something else, only the spectrum can prove it.

In the case of NGC1154, The Wait was only about 14 hours which is very short, but it can take days, such as Stu's recent discovery in NGC10.

Hi all,
now this is great news..the Central Bureau for Astronomical Telegrams (CBAT) has issued an electronic telegram advising that the SN in NGC1154 is now recognised as SN2011jp, and even better, it follows consecutively from Stu's latest find in NGC10 (that I analysed and reported) as SN2011jo...


So, BOSS has a pair of discoveries, both type IIP, together in the SN list for 2011....yes, yes, yes.

CONGRATULATIONS Greg and BOSS TEAM.
That sure does look like a beauty. All your hard work is inspirational to us all.
Well deserved admiration.:thumbsup:

HI All,
thanks for your best wishes, I really appreciate them.
We had clear skies last night, so I took a 15 minute image of SN2011jp and posted it here to help anyone who is interested in locating it for themselves. If you do, just remember that this galaxy lies at a distance of about 200 million light years, so it will be small and faint when you see it!

Good luck,

Can I use that image for the Event HorizonGreg?
Or will you send me a copy and some further blurb?
What you sent is pre confirmation

Hi Jen,
I'll send some info soon to you for EH.
