V834 CARINAE = NOVA CARINAE 2012
John Seach, NSW, Australia reported his discovery of a possible new nova 
of mag 10.2 on three CCD images (limiting mag 11.0) obtained on 2012 
Feb. 26.543 UT with an SLR camera and 50-mm f/1.0 lens. The new object 
is located at:
RA 10h50m20s DEC -64 06'48" (2000); nothing is present at this position 
on his image from Feb.23.42 (limiting mag 11) or on a red Palomar Sky 
Survey image.

Additional observations: Mar. 1.155, V = 10.55 (Arto Oksanen and C. 
Harlingten, 0.50-m telescope at San Pedro de Atacama, Chile; position 
end figures 19s.66, 46".7); 5.323, V = 10.87 (Oksanen);
7.296, V = 11.21; 10.375, V = 11.54 (Oksanen); Oksanen notes that a 
nearby very faint star is visible near the plate limit (mag perhaps
19) on a red U.K. Schmidt telescope IIIa-F plate (RG610 filter) taken on 
1994 Apr. 9, but he adds that the star is not exactly at the position of 
the presumed nova.

F. M. Walter, Stony Brook University; and M. Hernandez, Cerro Tololo 
Interamerican Observatory, obtained a spectrogram on Mar. 7.01 UT 
suggesting a classical "Fe II" nova near maximum.
(extracted in part from IAUC 9251).

SUPERNOVA 2012au IN NGC 4790 (CSS)
2012au  Mar 14.45   12 54 52.18  -10 14 50.2  13.8   3.5"E    2.0"N
J. M. Silverman et. al., spectrum Mar 15 shows type-Ib with very 
well-developed He I lines, likely near maximum brightness.

Mar 15.319, 13.6 (Joseph Brimacombe, Cairns, Australia; remotely using a 
51-cm RCOS telescope + STL11K camera + luminance filter at the New 
Mexico Skies Observatory near Mayhill, NM, U.S.A.; position end figures

As the image on the extreme right shows, the supernova is very close to 
the nucleus of the galaxy.
