BIG congratulations to Stuart Parker (Park123) for his 8th Supernova discovery SN2010bv in PGC 68345 aka ESO 533-4. As reported in CBET 2255 (official notification from Central Bureau Astronomical Telegrams -International Astronomical Union).
PGC & ESO being catalogue numbers in the Principal Galaxy Catalogue & European Southern Observatory.
Stuart will no doubt have something to say here about his latest as soon as he gets some sleep.
In the meantime, with assistance from other members of the BOSS team (Backyard Observatory Supernova Search) we were able to very quickly check all the data/catalogues etc, and then double check. Member Colin Drescher (data whizz king perfecto) sent the precise details in a report to CBAT.
All in all that brings the BOSS collective count to 11 SN in just over a year (Stu's 8 in 10mths) and this expected to grow very quickly over the next few years.
A big thanks must go to Joseph Brimacombe (Cairns) for his prompt assistance (as usual and at all hours) in obtaining a confirmation image using some of the many professional setups he has access to around the world. Joseph has turned into THE most prolific imager of reported SN discoveries in the world, there is rarely one he doesn't image, just astonishing his contribution to this area alone.
Can't forget to thank Steve Quirk who has been available at a moments notice, again at all hours of the night on recent occasions that ended up being nothing.
The magnitude of the Supernova is 15.4 so a little faint for most backyard visual observers.
We don't yet know if it is brightening and will keep this thread up to date with any relevant information. It's a very early morning object and imagers here encouraged to have a go because it stands out like, well... you know...
We don't know the type yet (the professionals will get a spectra to determine this) i.e. Type 1a, White Dwarf star siphons matter from a companion Red Giant star until it exceeds a certain mass and BANG! or a Type II (2) where a relatively young Gigantic star (several times the mass of the Sun) has exhausted its fuel supply. With the outward pressure that had supported the star for so long now gone, the star collapses in on itself as gravity wins the battle, a shockwave rebounds off the iron core, BANG! there goes a nudder one. For a while outshining its host galaxy, it's light travelling for perhaps tens of or hundreds of millions of years to end up on Stuart Parkers ST8 CCD chip, mounted to his C14 on his Paramount on his dairy farm in NZ, the biggest BANG in the universe (well pretty much) doesn't wake his wife or upset the cows! And Stu is a happy boy, again!
