I had a bit of luck around 11pm last night in finding the BOSS teams 40th Supernova and my personal 5th discovery.
The galaxy ESO145-04 (aka PGC66545) is located in Indus, it is a pretty edge on spiral at magnitude 14 around 140 million light years distant. The suspect SN is around magnitude 15.6
IIS imagers are invited to make follow up images that can be sent to Dave Bishop at the Bright Supernova site below. http://www.rochesterastronomy.org/snimages/
Joe Brimacombe has a follow up image at the link below.
Greg Bock was able to get the necessary discovery data posted quickly on the Harvard TOCP site (see below).
I have attached the discovery image, it's not a Mona Lisa like many of our great imagers here on IIS are producing but it sure made me smile!
We are now awaiting a spectra to determine the type of supernova.
Top stuff Peter - gee you BOSS folks have a prodigious output of discoveries! A testimony to the hours of effort and long vigils spent at the ‘scope and screen!
Thanks for the comments they are all really appreciated. Wo that's 2 for me this year in 6000 images.
Out of interest and just for bit of fun tonight I wanted to see what the shortest exposure would be useful to blink using the 12inch LX200R (@F7) in alt az mode and Starlight XPress SXVHR9 Monochrome camera. Well again it's no oil painting but it is only a 5 second image. Not bad shows a mag15.5(r) supernova quite easily.
Seems the PSN has brightened and has now been queued for a spectra by the professionals.
Thanks again from all in the BOSS team - Greg, Stu, Colin, Pat and Brendan they all share in this discovery and we are proud to let IIS members know about these discoveries almost as they occur and about the same time they are advised to the pros. Also thanks to Roger Groom for his collaboration with us when we need a follow up image from the west - he is always willing to do so at a moments notice.
Thanks guys.
The spectra has now been done and its an energetic type2 supernova caught not long after the core collapse. It is of real scientific interest to the professionals and is brightening. The email BOSS received today from a Harvard astronomer is so encouraging ...noting "you guys are landing some great targets" and ending with "rock on" - really from a Harvard astronomer how cool are these guys.
So we have an Astrofest supernova. I suppose I can autograph images taken of this SN at Astrofest hehe, geez I am sounding like a wacker (that's wacker) - ok I have had a few CCs and Pepsi max.
Will it brighten enough to be a visual object in big scopes at Astrofest.. well maybe. We are just awaiting the official announcement from CBAT with its new name.
HI all,
well, this one is brightening quickly too, about mag 15 last night, so it will be a good imaging target for any astro-imagers using focal lengths of 1500mm or more (rough guess, so don't hold me to that value!) at Queensland Astrofest next week.
Should also be a visual target in larger scopes too, good luck!
hi pet,
tried to find your s/n tonight...i was able to see the galaxy with very averted vision at around 102x up to 296x but but that little speck that you can see with your cameras wasn't seen with my 14"sct bugger...spent around an hour with many eyepieces and double checking my position and i,m 100 percent positive i was on the galaxy..going to keep on trying over the next couple of weeks to see if can be seen...it also sounds as if it's brightening.....
Good onya for trying Mozzie. Will definitely be a good Astrofest target for imagers and crossing fingers I hope to see it in Peter Robbins 30inch - he informs me he will be there on the second weekend.
Regards
Peter

Hi Peter,I also will be giving it a whirl from here on the weekend with the 16', and hopefully it will brighten enough for me to see it
So happy for you and the team
Cheers
Congratulations Peter. Here's hoping it will still be bright enough for imaging and observing at Astrofest.
