VSNET Weekly Campaign Summary
*** Last week news ***
(new targets)
Nova Sgr 2003 No.2 (RA = 18h10m10s.42, Dec = -27d45'35".2)
IAUC 8204 informed the discovery of Nova Sgr 2003-2 by
N. J. Brown. W. Liller reported that a grating spectrum showed a
prominent H-alpha emission, indicating its nova nature
(vsnet-campaign-nova 1452, 1456, 1457, 1461, 1462). On photographs
taken by H. Nishimura on September 17, the object was recorded with
10.4mag (vsnet-campaign-nova 1467). K. Haseda's observation showed
that it was 9.7p mag on Sep. 17 (vsnet-campaign-nova 1474).
T. Hishikura's observation shows that it was fainter than 9.9p mag
on Sep. 14 (vsnet-campaign-nova 1471). The object is now fading
(vsnet-campaign-nova 1463, 1465, 1466, 1472, 1478).
V551 Sgr (RA = 18h00m56s.46, Dec = -34d35'45".6)
As reported by R. Stubbings on September 20, the suspected SU
UMa-type dwarf nova (possibly related to WZ Sge-type objects?) V551
Sgr is undergoing a relatively bright outburst. Urgent
time-resolved photometry is encouraged. The last outburst in 2003
April was a short outburst. The last reported long outburst
(superoutburst?) occurred in 2001 May; the reported brightness
(13.8mag by R. Stubbings on Sep. 20) already surpasses the reported
maximum of the 2001 May outburst (vsnet-campaign-dn 3945).
B. Monard reported the light curve only showed low amplitude
modulations on Sep. 21/22 (vsnet-campaign-dn 3961, 3962, 3963). The
outburst is still ongoing (vsnet-campaign-dn 3948, 3957).
New/brighter object near HX PEG?
(RA = 23h40m03s, Dec = +12d36'45")
M. Linnolt reported a possible new object with 14.6mag on
September 20.3479-3715 UT near HX Peg (vsnet-campaign-unknown 212).
T. Kato commented that the ASAS-3 apparently did not positively
record this object vsnet-campaign-unknown 213). M. Simonsen
reported the confirmation of the object with 14.6mag on Sep. 20.409
(vsnet-campaign-unknown 224). After three hours from the first
report, M. Linnolt reported that the object faded by 0.5mag, and
that it might be an optical afterglow of a gamma-ray burst
(vsnet-campaign-unknown 214, 215, 216, 218, 220, 222, 225, 226, 227,
236, 241, 246, 247, 248, 249). T. Vanmunster performed CCD
observation and detected no new object brighter than 16.5mag on
Sep. 20.78 (vsnet-campaign-unknown 217, 229). R. Novak also
reported no apparent new object on his CCD images
(vsnet-campaign-unknown 219). It may be possible that the rapid
fading observed by M. Linnolt is consistent with these negative
observations (vsnet-campaign-unknown 223). No positive detection
had, then, been reported (vsnet-campaign-unknown 231, 235, 232, 233,
228, 245), but in the image taken by Keck 10-m telescope on 07UT Sep
21, M. Linnolt noticed a possible faded object
(vsnet-campaign-unknown 237). T. Kato commented that it more looks
like a faint galaxy (vsnet-campaign-unknown 238, 239, 240).
A. Henden reported that the 155 comp star is variable similar to an
RR Lyr (vsnet-campaign-unknown 242, 243, 244). On Sep. 22,
M. Linnolt reported a rebrightening of the object during 10UT
(vsnet-campaign-unknown 250). The nature of the object? is still
uncertain. Close CCD monitoring is encouraged. The summary of
observations can be seen at [vsnet-campaign-unknown 230].
V344 Pav (RA = 19h16m10.21s, Dec = -62d35'54".4)
An outburst to 14.4mag was reported by R. Stubbings on September
20. The last reported outburst was in 2001 April-May
(vsnet-campaign-dn 3950). The outburst continues (vsnet-campaign-dn
3959).
IGR J17544-2619 (RA = 17h54m.4, Dec = -26d19')
According to ATEL #190, INTEGRAL discovered a new X-ray transient,
IGR J17544-2619 (vsnet-campaign-xray 261). B. Monard reported no
new object was apparent in the error box of the position, but he
also reported two possibly brightening objects of 19.4 and 19.0mag,
which might be an optical counterpart (vsnet-campaign-xray 262, 263).
He reported later that no significant change in brightness of any of
the field stars was noticed on images of the respective nights 17 to
19 Sep 2003 (vsnet-campaign-xray 264, 265).
SN 2003hz (RA = 05h48m07s.86, Dec = +46d15'22".8)
SN 2003hz is hosted by PGC 17866, a spiral galaxy near the
Galactic plane. The expected maximum for typical SN Ia is
consistent with the discovery magnitude (16.7-16.8mag)
(vsnet-campaign-sn 692). The CfA team also revealed that it is also
a type Ia SN, about a week after maximum with a Sept. 19.51 UT
spectrum (vsnet-campaign-sn 696).
SN 2003ia (RA = 16h17m41s.17, Dec = +35d00'07".2)
SN 2003ia is hosted by NGC 6109, a lenticular galaxy. The
morphology of the host galaxy suggest that it would be a type Ia
SN, whose expected maximum is consistent with the discovery
magnitude (17.2-17.3mag) (vsnet-campaign-sn 693).
SN 2003ib (RA = 20h33m30s.98, Dec = -24d37'15".0)
SN 2003ib is hosted by MCG -04-48-15, a spiral galaxy. There are
several foreground stars around the host galaxy. It is probably a
member of a cluster Abell 3698. If it is the case, the expected
maximum for typical SN Ia is mag about 16.3 (vsnet-campaign-sn 693).
SN 2003ic (RA = 00h41m50s.23, Dec = -09d18'19".0)
SN 2003ic is hosted by MCG -02-2-86, a giant elliptical galaxy in
a cluster Abell 85. It is likely a SN Ia near maximum
(vsnet-campaign-sn 693).
SN 2003id (RA = 02h21m35s.70, Dec = -05d31'51".0)
SN 2003id is hosted by NGC 895, a nearby spiral galaxy. The
expected maximum for typical SN Ia is mag about 14.2. The discovery
magnitude is about 16.7mag, so it seems to be a gravitational
collapsed event and/or absorbed SN (vsnet-campaign-sn 693).
Y Cyg (RA = 20h52m03s.6, Dec = +34d39'27")
D. West reported that the Algol-type eclipsing binary, Y Cyg is
now brighter than usual (vsnet-campaign-ecl 88). M. Zejda
reported that the ascending branch was observed on July 7 2003
(vsnet-campaign-ecl 89).
IX Dra (RA = 18h12m32s.2, Dec = +67d04'41")
The object experienced an outburst with 14.5mag as reported by
M. Simonsen. It may be a superoutburst (vsnet-campaign-dn 3952).
V1316 Cyg (RA = 20h12m12s.68, Dec = +42d45'53".0)
A possible outburst was reported on September 21, but not
confirmed (vsnet-campaign-dn 3953, 3954, 3955, 3956).
3C 66A (RA = 02h22m39s.6, Dec = +43d02'08")
The object is reported slightly brighter (vsnet-campaign-blazar 312).
RR Tau (RA = 05h39m30s.53, Dec = +26d22'26".3)
The object is now 10th mag. It is gradually brightening
(vsnet-campaign-orion 62).
SN 2003ie (RA = 12h03m18s.15, Dec = +44d31'34".6)
SN 2003ie is hosted by NGC 4051, a nearby spiral galaxy. This
galaxy had also produced SN Ic 1983I, whose maximum was mag about
13.7 (vsnet-campaign-sn 696).
(continuous targets)
V585 Lyr (RA = 19h13m58s.5, Dec = +40d44'09")
In an early outburst phase, the light curve only showed a possible
small modulations. A periodicity of ~0.1 day was suspected
(vsnet-campaign-dn 3928, 3929, 3934). J. Pietz reported 0.3-mag
clear humps on September 17 (vsnet-campaign-dn 3933). T. Krajci
confirmed similar modulations on September 18 (vsnet-campaign-dn
3938). With these observations, the SU UMa nature of V585 Lyr was
established, and T. Kato calculated a preliminary superhump period
of 0.0603(3) d. The period is relatively short, and T. Kato
commented that the object seems to bear some resemblance to SW UMa
in its outburst properties and superhump profiles (vsnet-campaign-dn
3939). The superhump period was refined to be 0.06022 d on Sep. 22
(vsnet-campaign-dn 3941, 3943, 3960). R. Novak reported superhumps
were clearly visible on Sep. 21/22 (vsnet-campaign-nova 1477). As
expected from the shortness of the superhump period, T. Kato
reported on Sep. 22 that there is already evidence of positive
period change. The preliminary superhump period derivative is at an
order of dot(P)/P = +6x10^(-5) (vsnet-campaign-dn 3960). The
superoutburst is still ongoing (vsnet-campaign-dn 3926, 3930, 3935,
3940, 3942, 3947, 3958).
SN 2003hx (RA = 05h46m46s.97, Dec = -16d47'00".6)
An ESO spectrum taken on Sept. 15.4 UT suggest that it is affected
by significant dust extinction (vsnet-campaign-sn 693).
ES Aql (RA = 19h32m21s.58, Dec = -00d11'31".2)
It was reported to be 14.5mag on Sep. 21. It may be recovering
from the deep minimum (vsnet-campaign-rcb 155).
SN 2003gx (RA = 01h02m55s.09, Dec = +37d40'10".3)
The CfA group obtained a spectrum of this SN on Sept. 18.42 UT,
which revealed that it is type II SN (vsnet-campaign-sn 695).
SN 2003hu (RA = 19h11m31s.40, Dec = +77d53'35".2)
The CfA team has revealed that it was type Ia SN near maximum on
Sept. 19.20 UT. The redshift of the host galaxy was quite larger
than that of UGC 11423 (vsnet-campaign-sn 696).
TY Psc (RA = 01h25m36s.87, Dec = +32d23'05".3)
The superoutburst continues (vsnet-campaign-dn 3936).
CH UMa (RA = 10h07m00s.90, Dec = +67d32'45".0)
The object is now in outburst. It reaches 11th mag now
(vsnet-campaign-dn 3925, 3937, 3951).
IP Peg (RA = 23h23m08s.7, Dec = +18d24'59".1)
A faint outburst was reported on September 15 (vsnet-campaign-dn
3927, 3949).
V475 Sct (RA = 18h49m37s.60, Dec = -09d33'50".85)
C. Buil reported that the H-alpha and H-beta line significantly
start to fading (vsnet-campaign-nova 1438, 1470). The
object is now brightening (vsnet-campaign-nova 1446, 1475).
V Sge (RA = 20h20m14s.75, Dec = +21d06'09".0)
The object is now fading again (vsnet-campaign-nl 137).
Z UMi (RA = 15h02m01s.35, Dec = +83d03'48".7)
It is now 15th mag, keeps fading (vsnet-campaign-rcb 154).
AM Her (RA = 18h16m13s.4, Dec = +49d52'03".1)
The faint state continues (vsnet-campaign-polar 36).
MisV1147 (RA = 22h54m03s.78, Dec = +58d54'02".1)
A new fading event was reported in mid-September
(vsnet-campaign-orion 61, 63).
AG Car (RA = 10h56m11s.6, Dec = -60d27'13")
S. Otero reported that the brightening of the SDOR star, AG Car is
now slow and gradual. It is now 6.2mag (vsnet-campaign-sdor 50, 51, 52).
