Supernova Number33

[PeterM]

Stu Parker has just discovered the 33rd Supernova as part of the BOSS team collaboration.
It is in PGC62253 aka ESO336-9 in Corona Australis. The Galaxy is a somewhat faint 14.6 magnitude with the supernova at mag 14.5
It may indeed be of interest to imagers on IIS and perhaps those with big scopes to have a go at visually.
Seems there is some excitement yet again from our professional friends who will interupt some other projects tomorrow evening to obtain a spectra with one of the Magellan scopes in Chile. There is some discussion around the brightness of this supernova at a reasonably large distance.
Good onya Stu and the BOSS team members who took time at work with no astro tools available to get a position and report sent off.
Stu will post images shortly, but if its clear where you are the galaxy is on the rise in the SE.
Side note Stu has taken some 6000 images this month, I managed 1000 and Greg had about 500ish.

Well done Stu and the BOSS team
Not much chance of getting a look at the moment as it is raining and possibly going to be for the next few days
I have an image of the galaxy,and it looks like rather small and faint, so maybe out of range of my scope but will give it a try when the weather improves.
Cheers

Congratulations and well done again to Stu & the Boss team.
You guys sure are keeping them busy up there in Chile.

the outline of this galaxy is very small, in the DSS image found at the www.wikisky.org virtual telescope.

Good luck folks.....a very challenging object!!

The outline of this galaxy tentatively indicates that there is some morphological distortion and/or perhaps some galaxy merger/interaction activity that is going on.

The ESO Schmidt (red wavelengths) plate, scanned with MAMA, which can be viewed at
//aladin.u-strasbg.fr/AladinPreview
shows a high surface brightness galaxy that may well have a high Massive Star Formation rate and therefore a high rate of core-collapse supernovae.

HI all,
just a quick note to let you know that Stu's 25th supernova discovery which was reported by Col has now been recognized and named as SN2012ca.

Extract of the report from CBAT reads:

SUPERNOVA 2012ca = PSN J18410706-4147374
Colin Drescher, Calamvale, Queensland, Australia, reports the discovery of an apparent supernova (red mag 14.8) by Stuart Parker (Oxford, Canterbury, New Zealand) in the course of the Backyard Observatory Supernova Search on a 30-s unfiltered CCD image taken on Apr. 25.587 UT using a 35-cm Celestron C14 f/6.3 reflector (+ ST10 camera). The new object is located at R.A. = 18 41 07.25 Dec -41 47 38.4 (equinox 2000.0), which is 8" west and 4" north of the nucleus of the galaxy ESO 336-9.

PEESTO collaboration report that an optical spectrum obtained on Apr. 29.40 UT by the 3.6-m New Technology Telescope (+ EFOSC2) at La Silla, shows it to be a type-IIn supernova, at about 20 days from the presumed explosion epoch.

Stu has updated the BOSS homepage with the new designation, and photos. go here http://bosssupernova.com/
