Another new SN in the south found by the BOSS team here in Australia and NZ.
This one is the brightest yet at V = 11.8 when I took a spectra.
I have put the data on a page here

Terry,
Well done!
I'm surprised there's be no comments by other members of the forum....
It's certainly not every day a bright SN like this is found and amateur spectra obtained so quickly.....

Terry's second transient confirmation in a few days. Great stuff !
Just beaten to the post by the pros on this one

but first with GR Ori

With this SN being so bright (and still on the rise?) it should be possible to track its evolution spectroscopically for some time. Looking forward to more spectra
Cheers
Robin

I now have taken 4 nights of spectra of this SN over a 4 week period. The weather was very poor for the first 3 weeks so there is a big gap in the data.

Hello Terry,
Excellent. A good survey of this SN.
The comparison with Gelato spectra is very interesting. A great tool.
Bonne continuation
François
