AAVSO ALERT NOTICE 330 (November 30, 2005)

SUBJECT: NOVA LMC 2005 - Nova in the Large Magellanic Cloud

Object: 0511-69 N LMC 05

Discovered By: William Liller, Vina del Mar, Chile

Discovery Magnitude: 11.5 V (Tech Pan film, unfiltered, using a 0.2-m
Schmidt camera)

Discovery Date: November 26.164 UT

Position: Peter Nelson, Ellinbank, Victoria, Australia, forwards the
following position measured from a CCD image taken by him on November
27.5833 UT:
R.A. = 05h 10m 32.68s (2000.0)
Decl. = -69o 12' 35.7" (2000.0)
Please note that this position is not the one given by B. Allen in IAU
Circular 8635; that position is incorrect.

Spectra: A low-resolution spectrogram taken Nov. 28.28 UT by F. M. Walter,
Stony Brook University, A. Pasten, Cerro Tololo Interamerican Observatory
(CTIO), and H. E. Bond, Space Telescope Science Institute, using the
SMARTS/CTIO 1.5-m telescope (+ RC spectrograph), indicates a classical
nova near maximum (IAU Circular 8635, ed. D.W.E. Green).

Chart: A chart (approximately 18x13 arcminutes) made by Mati Morel and
revised by E. Waagen, AAVSO, is available at
www.aavso.org/charts/DOR/N_LMC_05/N_LMC_05.GIF

Report Object to the AAVSO as: 0511-69 N LMC 05

Notes:
a. Liller notes nothing was seen at this position down to magnitude 13 on
earlier images through November 20.

Congratulations to Bill on his latest discovery!

Yet again I wish I lived in the southern Hemisphere!

Me too Bart

I suppose its just a matter of time before a bright one apears in the north again? Are we over due a bright one? Keith whats your thoughts on this?

Clear skies!

Now do you mean Nova or Supernova? The last nova within our galaxy I can remember was Nova Cygni 1992 (V1974 Cygni) in February 1992.

Now, we are due a supernova. The last one in the Milky Way that occured favourably to Northern hemisphere observers was in 1604. The last big supernova altogether was 1987A in the LMC (Taratnula Nebula). So we're not necessarily overdue another supernova as such!

Thanks Seannie, i meant Nova in our own galaxy. What was the mag of the 1992 Nova?

Cheers

The brightest it got to was around magnitude 4.5, so it was readily visible with the naked eye for a couple of weeks. Terry Mosley talked about it at Astrofest '92, as he was in the running for crediting its discovery (which went to someone else in the end!).
