NOVA CANDIDATES IN MESSIER 31
W. Pietsch, Max Planck Institut. et. al., report on Astronomer's 
Telegram 850 the spectroscopic confirmation of four recent optical nova 
candidates in M31 using the 2.2 m telescope and the Calar Alto Faint 
Object Spectrograph  CAFOS at CAHA on Calar Alto, Spain.

The outburst of the apparent nova M31N 2006-06a,
(RA 00:43:11.81,DEC +41:13:44.7 (J2000) occurred between 2006 May 12 and 
May 22, with an R band magnitude of 17.6 and white light magnitude of 
18.0 at maximum. A spectrum obtained on 2006 June
27.12713 shows the object to be a Fe II nova.

The outburst of the apparent nova M31N 2005-09a,
RA 00:42:52.30, DEC +41:19:58.3 (J2000)) occurred between 2005 Sep 12 
and 13, with a white light magnitude at maximum of 16.1. Our spectrum 
obtained on 2005 Sept. 19.08361 shows the object to be a Fe II nova.

The outburst of the apparent nova M31N 2005-09b,
RA 00:38:49.49, DEC +40:19:58.3 (J2000)) occurred between 2005 Aug 31 
and Sep 1 with a white light magnitude at maximum of 16.5. An early 
spectrum identified the object as a young Fe II or hybrid nova.

The outburst of the apparent nova M31N 2005-06d,
RA 00:45:05.20, DEC +41:33:39.8 (J2000)) occurred between 2005 Jun 8 and 
15, with a white light magnitude at maximum of 15.7. Our spectra 
obtained on 2005 Jun 16.12269 and Jun 16.14569, show the object to be a 
hybrid nova several days after outburst.

SUPERNOVA 2006dm IN MCG -01-60-21
Discovery by Lick Observatory Supernova Search of a possible supernova 
(IAUC 8728):
SN      2005 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2006dm  July 03.44  23 41 47.84  -03 40 08.4  17.3    7.6"E, 6.3"S
It is a type-Ia supernova found a few days before maximum.
