OUTBURST OF CATACLYSMIC VARIABLE 1RXS J231935.0+364705
D.V. Denisenko, Moscow reports on The Astronomer's Telegram 2282 the 
first real-time detection of the outburst (from 19.0 mag to 14.5 mag on 
2009 Nov. 5 of an optical counterpart of the poorly studied ROSAT X-ray 
source 1RXS J231935.0+364705 in Andromeda.

In 2007 it was identified with NSVS 9022680
(see http://hea.iki.rssi.ru/~denis/NSVS9022680.gif).
NSVS 9022680 showed a dwarf nova-like outburst in 1999 November. Due to 
the poor angular resolution of ROTSE-I (14") this object is actually a 
blend of two stars separated by 18.5". The fainter (north-western) star 
is showing outbursts. The name and coordinates of the new cataclysmic 
variable are: USNO-B1.0 1267-0564384
RA 23h 19m 36.06s DEC +36 47' 00.3" (2000).

The colour-combined (BRIR) 10'x9' DSS finder chart of RX J2319.6+3647 is 
available at http://hea.iki.rssi.ru/~denis/J2319+3647-comps.gif 
(position of the variable object is marked with dashes). Another 
outburst was recorded on the POSS-II infrared plate taken on 1995 Aug. 
28.

The new variable was monitored with the Bradford Robotic Telescope since 
2009 October. The following photometry has been obtained: Time (JD) 
YYYY-MM-DD.ddd   R mag
2455121.542  2009 10 17.042  18.74
2455127.552  2009 10 23.052  18.96
2455140.522  2009 11 05.022  14.48

The outburst amplitude (about 4.5 mag) and duration of the 1999 outburst 
in ROTSE data suggest that the new variable is a dwarf nova of the SU 
UMa (UGSU) subtype.

SUPERNOVA 2009iv IN ANONYMOUS GALAXY
Discovery by the ROTSE collaboration of a possible supernova (CBET 
1940):
SN      2009 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2009iv  Aug 21.43   02 58 14.19  +05 58 19.3  17.6
The object is consistent with the core of the apparent host galaxy, 
2MASX J02581424+0558189, at a redshift of z = 0.023 (according to the 
SIMBAD database). Two spectra of Aug. 29.43 and Sept. 9.72 with the 
9.2-m Hobby-Eberly Telescope, show 2009iv to be a type-Ia supernova.

SUPERNOVA 2009iw IN IC 2160
Discovery by Stuart Parker, Oxford, Canterbury, New Zealand of a 
possible supernova (CBET 1942):
SN      2009 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2009iw  Sep 15.62   05 55 25.63  -76 55 15.9  15.0R   10  "W, 3  "S
The peculiar-type-Ia supernova 2009J also appeared in IC 2160

SUPERNOVA 2009ix IN ANONYMOUS GALAXY
Discovery by LOSS of a possible supernova (CBET 1943):
