VSNET Weekly Campaign Summary
*** Last week news ***
(new targets)
V585 Lyr (RA = 19h13m58s.5, Dec = +40d44'09")
An outburst of 13.7-13.9mag was reported on September 14 by
M. Simonsen. This object is a suspected SU UMa-type dwarf nova.
The last reported outburst was on 2001 October 31, reaching mag
about 14.0. This outburst was likely a short outburst
(vsnet-campaign-dn 3913, 3914). R. Novak performed time-series
observation and reported that no periodic variation was detected
(vsnet-campaign-dn 3921). In the light curve observed by J. Pietz
on Sep. 14/15 showed 0.1-mag superhump-like modulations
(vsnet-campaign-dn 3922). Further time-series observations are
encouraged.
SN 2003hv (RA = 03h04m09s.32, Dec = -26d05'07".5)
IAUC 8197 reported the discovery of SN Ia 2003hv (mag about 12.5
on Sept. 9.5 UT) by the KAIT group. It is the brightest supernova
so far in this year (vsnet-campaign-sn 685). The host galaxy, NGC
1201, is a member of Eridanus-Fornax group, which has the nearly
same distance (a bit further) as the Virgo cluster
(vsnet-campaign-sn 686). The Carnegie Observatories team also
reported that it is of type Ia near maximum (Sept. 10.36 UT
spectrum) (vsnet-campaign-sn 687, 689, 690).
NSV 10934 (RA = 18h40m52s.26, Dec = -83d43'10".24)
A bright outburst (12.2mag) was detected by R. Stubbings on
September 14 (vsnet-campaign-dn 3915).
SN 2003hx (RA = 05h46m46s.97, Dec = -16d47'00".6)
SN 2003hx is hosted by NGC 2076, a lenticular galaxy with a dust
lane. The morphology of the host galaxy suggests that it is
probably of type Ia, whose expected maximum is mag about 14.2
(vsnet-campaign-sn 688). The ANU group revealed that it was a type
Ia SN, near maximum on Sept. 13.78 UT (vsnet-campaign-sn 691).
SN 2003hy (RA = 21h54m22s.72, Dec = +15d09'38".7)
SN 2003hy is hosted by IC 5145, a spiral galaxy. IC 5145 also
produced SN Ic 2002dn, which was caught at mag about 18.6 about a
week after maximum. The expected maximum for typical SN Ia is
consistent with the discovery magnitude of SN 2003hy (=16.3-16.6mag)
(vsnet-campaign-sn 691).
SN 2003hu (RA = 19h11m31s.40, Dec = +77d53'35".2)
SN 2003hu is hosted by an anonymous galaxy with a bright nucleus.
If the host galaxy and the new object is at the same distance as UGC
11423, the expected maximum for typical SN Ia is mag about 16.9
(vsnet-campaign-sn 684).
SN 2003hw (RA = 03h01m50s.02, Dec = +35d44'36".4)
SN 2003hw is hosted by 2MASX J03014982+3544343, a small galaxy
located at 1' west-northwest of UGC 2491. The host galaxy is
probably a member of a cluster Abell 407 (v_r = 13850 km/s), on
the other hand UGC 2491 is a foreground galaxy (v_r = 4875 km/s)
(vsnet-campaign-sn 687).
DH Aql (RA = 19h26m12s.05, Dec = -10d15'21".4)
P. Schmeer reported an outburst of this SU UMa star on August 2.
The last superoutburst was detected by R. Stubbings on 2003 July.
The object is still bright (~12.5mag) now, indicating a
superoutburst (vsnet-campaign-dn 3888, 3889, 3890, 3896, 3903, 3905,
3909, 3912). The object is now fading from the superoutburst
(vsnet-campaign-dn 3916).
DV Sco (RA = 16h50m26s.7, Dec = -28d08'00")
According to IBVS No. 5448, DV Sco is now suggested to be a dwarf
nova from photographic plate search. T. Kato noticed that the
object is identified with the ROSAT source 1RXSJ165029.0-280811,
which further strengthens the classification as a cataclysmic
variable. The X-ray spectrum is relatively hard. Further
monitoring for outbursts is encouraged (vsnet-campaign-dn 3893).
SN 2003hq (RA = 16h33m40s.90, Dec = +50d22'37".7)
SN 2003hq is hosted by MCG +08-30-27, a spiral galaxy within a
group VV 667. IAUC 8192 informed that the UCB team revealed that it
was a type Ia SN near the maximum light (vsnet-campaign-sn 683).
SN 2003hr (RA = 08h24m39s.06, Dec = +73d24'23".3)
SN 2003hr is hosted by NGC 2551, a spiral galaxy. The expected
maximum for typical SN Ia is mag about 14.2, but the reported
magnitudes (16.8mag) indicate that it seems not the case
(vsnet-campaign-sn 683).
SN 2003hs (RA = 18h11m10s.93, Dec = +49d52'08".9)
SN 2003hs is hosted by UGC 11149, a spiral galaxy. This galaxy
also produced SN Ia 1998dx, whose maximum was mag about 17.9
(vsnet-campaign-sn 683). The UCB team revealed that it was of type
Ia, around maximum light on Sept. 3. It can be slightly subluminous
(vsnet-campaign-sn 684).
SN 2003ht (RA = 02h59m55s.17, Dec = +24d13'36".8)
SN 2003ht is hosted by UGC 2457, a spiral galaxy. The expected
maximum for typical SN Ia is mag about 18.0 (vsnet-campaign-sn 683).
V1294 Aql (RA = 19h33m36s.9, Dec = +03d45'41")
The object is now gradually fading from the normal state
(vsnet-campaign-be 255, 256, 262). Spectroscopic observations show
that the H_alpha emission is active. P. Harmanec reported that
V1294 Aql is known to be an object with an inverse correlation
between the brightness and emission-line strength already since our
1982 study (Horn et al. 1982 BAICz 33, 308) (vsnet-campaign-be 258,
259, 260, 263).
R Aqr (RA = 23h43m49s.5, Dec = -15d17'04")
It reaches the brightest maximum in the recent years
(vsnet-campaign-mira 72, 77).
V1329 Cyg (RA = 20h51m01s.3, Dec = +35d34'53")
The outburst continues. It is now 12th mag (vsnet-campaign-symbio
78, 79).
V1028 Cyg (RA = 20h00m56s.5, Dec = +56d56'37")
As reported by J. Pietz in [vsnet-outburst 5818], recently
discovered (e.g.,Baba et al. 2000) SU UMa-type dwarf nova V1028 Cyg
experienced a bright outburst on September 4 (vsnet-campaign-dn
3886, 3887, 3891). M. Uemura reported that it has faded to 15th mag
on September 7 (vsnet-campaign-dn 3894). No rebrightening has been
reported (vsnet-campaign-dn 3906).
V419 Lyr (RA = 19h10m14s.0, Dec = +29d06'15")

reported on August 28, but soon faded (vsnet-campaign-dn 3892).
IRAS 21443+4329 (RA = 21h46m21s.76, Dec = +43d43'53".7)
J. Greaves and P. Wils reported a new Mira star, which forms a
colorful double with a neighbor companion (vsnet-campaign-mira 73).
B. Skiff reported that it is identified with IRAS 21443+4329 and the
F/G dwarf companion (8" southeast) (vsnet-campaign-mira 74, 75).
1RXS J231603.9-052713 (RA = 23h16m03s.9, Dec = -05d27'13")
B. Monard reported that this polar has been around 16 CR mag since
July 2003, brighter than the recorded magnitude of 17.7B in the CV
atlas. It may be in a high state now (vsnet-campaign-polar 31).
TY Psc (RA = 01h25m36s.87, Dec = +32d23'05".3)
An outburst of 11.9mag was reported on September 7 by E. Muyllaert
(vsnet-campaign-dn 3897). The bright state still continues,
indicating a superoutburst (vsnet-campaign-dn 3904, 3908, 3911, 3918).

above precise position on the DSS 2 red image and the 2MASS public
images (vsnet-campaign-nova 1407, 1408, 1409, 1410). D. West
reported that the H_alpha emission is rather low for a typical novae
(vsnet-campaign-nova 1403). M. Fujii took a spectrum on September
13, which showed a strong H_alpha emission (vsnet-campaign-nova
1418). It is now about 9.0mag (vsnet-campaign-nova 1383, 1385,
