BOSS supernova 47, and my 4th supernova discovery.

[Greg Bock (Greg Bock)]

Hi all,
well, this is my 4th supernova discovery in just over 12 months since October last year, and it makes the 47th for BOSS.
I'm glad to say that the Aussie contingent of the BOSS team is picking up the pace a little at last!

Last night, I had taken about 140 galaxy images, and I discovered this new supernova after cheking about 70 images, at about magnitude 17.4R in a very pretty spiral galaxy that lies about 250 million light years away.
While I was checking those galaxy images, the scope was also taking a series of images of the new supernova, 2012fr in NGC1365. I had just finished about 17 minutes worth of images of NGC1365 when I had to stop imaging that galaxy and turn the scope onto a new faint object just west of the nucleus of NGC7298 that had just shown up in one of my SN search images .
It was just as well that I did that because NGC7298 was at a very low elevation of 25 degrees and setting slowly behind the observatory wall.
Luckily, I managed to get 18 30 second images under poor seeing conditions before it set behind the wall that were good enough to show that the new object was still visible, 3 hours after I had originally imaged it.
My luck also stretched out to tonight as well. I have just received advice that an Italian team imaged the new supernova 5 hours after I lodged the report on the Central Bureau's TOCP website. They report that the new object is a highly reddened type II supernova a few days after explosion.
If you wish to see this one, i have provided a finder chart here.
Also, it seems that we haven't kept up to date with the last 3 discoveries of the BOSS team. Sorry about that, I guess we have all been very busy lately.
If you would like to see some details of our previous discoveries, please visit our website here for the latest list of our discoveries.

STOP PRESS - my latest images of the new supernova show that it is brightening quite fast..will post the latest pic as soon as i can.

Clear skies,

Congrats again ... and again... and again...

Well done Greg
I don't think this one will get bright enough
to observe in my scope
Cheers

And here is tonight's image...happy hunting..gtg to bed now, only 4 hours sleep last night.

you never know Ron, until you give it a try mate..

[rogerg (Roger)]

Interesting. In my photo's of it I'm taking now I can't distinguish it from the core of NGC 7298.

Congratulations!!!

[rogerg (Roger)]

Here's my attempt.

10 x 180 seconds.
12" SCT @ 3080mm fl (f/10)
ST8 bin 2x2 @ -25
Image has been stacked (average combine), resized to 150% and sharpened in Photoshop.

I'm ashamed of the image quality. Trailing, awful reduction (both flat and dark), awful separation of the SN from the core.

Viewing conditions were average to poor, enormous star flicker and some cloud about.

Congratulations Greg!

This one's too teensy and faint for me though.

Hi Roger,
well, i wouldn't be ashamed of the image quality if I were you...not much you can do about the sky conditions. It seems that both you and Stu in NZ had poor seeing conditions compared to me on the east coast for a change. Usually, it's the other way around! Cloud rolled in shortly after my last exposure above, so I was lucky to get that image too.

On ya Greg!

[Terry B]

Well done!!

[Forgey (Paula)]

Awesome, well done!

[entity62]

Well done Greg.
I look forward too seeing if my video camera can pick this up. bring on the clear skies.

Congratulations Greg on #4- and what an achievement- four in the last 12 months and two of them were back to back (we were biting our nails in anticipation waiting on that hat trick- oh the pressure...!) which didn't happen BUT you nabbed the next one in good time anyway. It was the end of last year I believe when you got two in a row- I won't forget the excitement of that time easily.

Also a big congratulations to the BOSS team- I am just so ridiculously proud of you guys for such a great achievement. Great work team!
I really wish I could do what you guys are doing but if I'm going to be the next Sue French, I have to put my head down and keeping looking through that tube! Then again, I might surprise you by doing a Bob Evans on you
hmmm only one emoticon up there... soon fix that!

CONGRATULATIONS!!!

Well done Greg,

I will give this a fly visually next week from Coonabarabran in the 30" SDM.

Cheers,
John B

Whooa John, 30", that's just plain cheating. You'll need your sunnies too.

thanks guys, sorry its only a tiny one...i'm still kicking myself for missing the one in NGC1365 by one lousy day....Now that was THE SN find of the year!!

And, considering i did the confirmation image of 2001du in NGC1365 for Bob Evans in August 2001 at 4am, it would have been the icing on the cake to find the latest SN in NGC1365 for myself.

Oh well, back to the scope to find number 5.

I need a head start Greg. It would be a very good get in the 10" SDM

It's going to be tough in the 30 at mag 17+

Cheers,

This is getting soooooo routine, but well done you deserve it - all of you
