Hi all,
Its been about 5 discoveries since we reported here last and we are presenting only the bright ones that are visually available for IIS member observation or ones that are odd/unusual, as is the case below.
I discovered my 10th Supernova (and BOSS teams 81st) the other evening and it is generating some excitement with professional astronomers.
As one astronomer from Las Campanas Observatory in Chile noted " well done Peter, this one will get a lot of attention"
The new Supernova is classed as a rare subliminous Supernova or SN Iax, hopefully madbadgalaxyman can add some comment on this type of event.
Atel 5612 & 5613 (correction to the magnitude are listed below).
The Supernova is in PGC6512 aka ESO114-G7 in Hydrus and is V mag 17.2 and at this time (7.45pm Brissy time) is pretty much on the Meridian at 55 degrees altitude.
A link to the discovery image and data supplied by Greg Bock can be found at - http://www.rochesterastronomy.org/snimages/
As usual this is a BOSS team effort and I thank Greg Bock for pulling the data together and getting it posted. Colin Drescher provided great back up and Stu Parker was stuck under thick cloud. Pat Pearl and Brendan Downs were ready in the background if further follow up was needed. We really work well together.

Oh, and I must say and a BIG thanks to Greg Bryant from Australian Sky and Telescope for his inclusion of the BOSS team efforts in the latest Sky and Telescope article on the amateur hunt for Supernova.

We report the spectroscopic classification of PSN J01462790-5840238 using
a near-infrared spectrum (range 800-2400 nm) obtained on November 30.1
UT with the FoldedPort Infrared Echellette (FIRE) spectrograph on the 6.5-m
Magellan Baade Telescope at Las Campanas Observatory. The near-infrared
spectrum is similar to that of SN 2010ae near maximum light (Stritzinger
et al. 2013). The spectrum separately resolves the 3 components of the
Ca II IR-triplet (854.2, 866.2, 849.8 nm) and the velocity for Ca II is
approximately 5000 km/s, measured at the absorption minima and using a
redshift z=0.007385 for the presumed host ESO 114- G 007 (Koribalski et
al. 2004 AJ, 128, 16, via NED).
We also obtained uBVgri images with the Swope 1-m on Nov 29.0 UT. The un-subtracted
V magnitude is 14.2. Adopting the distance modulus of the presumed host
(32.1, via NED), the absolute V magnitude is approximately -15.0.
