VSNET Weekly Campaign Summary
*** Last week news ***
(new targets)
SN 2003cj (RA = 12h15m51s.90, Dec = +08d59'15".7)
SN 2003cj is hosted by a very dim (mag about 20) galaxy
(vsnet-campaign-xn 592).
SN 2003ck (RA = 13h06m21s.72, Dec = +03d04'21".0)
SN 2003ck is hosted by MAPS-NGP O_557_1733751, also a dim (mag
18.5) galaxy (vsnet-campaign-sn 592).
SN 2003cl (RA = 12h38m50s.11, Dec = -02d49'58."8)
SN 2003cl is hosted by 2dFGRS N186Z103, a distant (v_r = 50000
km/s) galaxy (vsnet-campaign-sn 592).
SN 2003cm (RA = 16h50m55s.02, Dec = +59d43'18".1)
SN 2003cm is hosted by UGC 10590, a face-on barred-spiral galaxy.
The expected maximum for typical SN Ia is mag about 14.8. The
reported magnitude is about 19.4, so it is very subluminous or
reddened or old event (vsnet-campaign-sn 592).
SN 2003cn (RA = 13h07m37s.05, Dec = -00d56'49".9)
SN 2003cn is hosted by IC 849, a face-on spiral galaxy. The Las
Campanas spectrum taken on Mar. 31.31 UT revealed that it was type II
SN about 2-3 weeks after explosion (IAUC 8102). The discovery
magnitude (18.1: mag) is typical for the gravitational-collapse
event (vsnet-campaign-sn 592).
SN 2003co (RA = 10h49m39s.91, Dec = +29d21'44".6)
SN2003co is hosted by 2MASXi J1049404+292152, a distant (v_r =
25000 km/s) spiral galaxy (vsnet-campaign-sn 593).
SN 2003cp (RA = 08h09m11s.13, Dec = +57d41'14".0)
SN 2003cp is hosted by MCG +10-12-78, a spiral galaxy. The
expected maximum for typical SN Ia is consistent with the
discovery magnitude (about 16.2mag) (vsnet-campaign-sn 593).
The CfA team reported that the spectrum taken on Apr. 1.18 resembles
that of SN Ia 2-3 weeks after maximum, but there are some
unusuality. H. Yamaoka reported that it can be somewhat younger
(vsnet-campaign-sn 596).
SN 2003cq (RA = 11h56m14s.17, Dec = +60d31'19".1)
SN 2003cq is hosted by NGC 3978, a face-on spiral galaxy making a
pair with 2' west NGC 3975. The expected maximum for typical SN Ia
is consistent with the discovery magnitude (about 17.0mag)
(vsnet-campaign-sn 593). The CfA team has revealed that it was type
Ia supernova, about a week before maximum on Apr. 3.28
(vsnet-campaign-sn 597).
SN 2003cr (RA = 14h58m35s.53, Dec = +44d53'06".4)
SN 2003cr is hosted by UGC 9639, a spiral galaxy. The expected
maximum for typical SN Ia is consistent with the discovery magnitude
(17.7-17.5mag) (vsnet-campaign-sn 593).
SN 2003cs (RA = 11h20m37s.52, Dec = -04d54'32".7)
SN 2003cs is hosted by 2MASXi J1120375-045437, a dim galaxy. The
discovery (early February) magnitude (about 17.9mag) is consistent
with the expected maximum for typical SN Ia (vsnet-campaign-sn 593).
SN 2003ct (RA = 11h22m56s.20, Dec = -02d56'59".9)
SN 2003ct is hosted by CGCG 011-083, a distant spiral galaxy. The
expected maximum for typical SN Ia is mag about 18.2
(vsnet-campaign-sn 593).
CC Cnc (RA = 08h36m19s.17, Dec = +21d21'05".4)
An outburst to 13th mag was reported by E. Muyllaert and H. McGee
on March 30 (vsnet-campaign-dn 3564).
SN 2003cu (RA = 10h53m02s.66, Dec = -00d41'03".9)
SN 2003cu is hosted by SDSS J105303.06-004107.1, an apparently
edge-on spiral galaxy. The expected maximum for typical SN Ia is
comparable to the observed magnitude (~20mag) (vsnet-campaign-sn 595).
SN 2003cv (RA = 11h17m48s.36, Dec = +19d09'08".5)
SN 2003cv is hosted by MAPS-NGP O_433_0206212, an apparently
disturbed spiral galaxy with mag about 19 (vsnet-campaign-sn 595).
SN 2003cw (RA = 11h24m03s.88, Dec = +23d20'44".8)
SN 2003cw is hosted by 2MASXi J1124038+232034, a dim galaxy
(vsnet-campaign-sn 595).
SN 2003cx (RA = 13h57m06s.46, Dec = -17d02'22".6)
SN 2003cx is hosted by a dim (mag about 18) galaxy, which has
stellar appearance on DSS images (vsnet-campaign-sn 596).
SN 2003cy (RA = 10h46m04s.27, Dec = +27d20'57".2)
SN 2003cy is hosted by an anonymous dim (rmag about 17) galaxy
(vsnet-campaign-sn 597).
SN 2003cz (RA = 12h05m53s.57, Dec = +33d27'13".0)
SN 2003cz is hosted by MAPS-NGP O_267_0568522, a dim (mag about
18.5) galaxy (vsnet-campaign-sn 597).
V729 Sgr (RA = 19h16m49s.15, Dec = -26d14'33".2)
The eclipsing dwarf nova V729 Sgr is in outburst as reported by
R. Stubbings on April 5 (vsnet-campaign-dn 3569).
AG Hya (RA = 09h50m30s.94, Dec = -23d45'03".7)
The outburst, which was detected by R. Stubbings on April 2, was
still ongoing on April 6 (vsnet-campaign-dn 3570).
Possible supernova in M3
A possible supernova was reported in M3. T. Kato reported that it
may be the Cepheid M3 V154, but further observations anc
confirmation are required (vsnet-campaign-sn 591).
KT Mon (RA = 06h25m18s.5, Dec = +05d26'32")
The 15-th mag magnitude in some catalogs refers to an incorrect
quiescent identification by Khatisov, A. S. (1971), which referred
to a GSC 2.2 star at 06:25:19.69 +05:26:32.9. The actual location
of KT Mon is void of a quiescent counterpart down to mag 20.
According to Kato and Yamaoka (2000), KT Mon can be either a WZ
Sge-type dwarf nova and an X-ray transient (vsnet-campaign-nova 1117).
theta CrB (RA = 15h32m55s.8, Dec = +31d21'33")
S. Otero reported that theta CrB is active again
(vsnet-campaign-be 227).
(continuous targets)
GRB030329 (RA = 10h44m50s.030, Dec = +21d31'18".15)
B. Monard reported that the afterglow remained constant at 16.7CR
between 19:51 and 23:35 UT on March 31 (vsnet-campaign-grb
16). Observations of the afterglow were reported to VSNET
(vsnet-campaign-grb 17, 18, 23, 25, 27, 19, 20, 21, 22, 24, 26).
CR Boo (RA = 13h48m55s.42, Dec = +07d57'30".3)
Reported observations may indicate that it is now in a oscillating
phase (vsnet-campaign-dn 3573).
AK Cnc (RA = 08h55m21s.21, Dec = +11d18'14".7)
The superoutburst continues (vsnet-campaign-dn 3562).
AD Men (RA = 06h04m28s.60, Dec = -71d25'15".6)
The light curve taken by B. Monard did not reveal a definte
periodicity, although there is a slight increase of a power around
period 0.06 d. Combined with the fading reported on March 31, the
object is likely an SS Cyg-type dwarf nova (vsnet-campaign-dn 3561, 3565).
IGR J17464-3213 (RA = 17h46m15s.61, Dec= -32d13'59".9)
B. Monard reported no bright counterpart was detected
(vsnet-campaign-xray 212, 214, vsnet-campaign 1380BR). E. Kuulkers
reported that apparently IGR J17464-3213's position is quite close
to the catalogued position of the black-hole candidate transient
H1743-322 (vsnet-campaign-xray 213). M. Rupen et al. reported that
the radio flux continues increasing and the spectrum can be
described with a flat spectrum, indicating a bright IR counterpart
(vsnet-campaign 1379, vsnet-campaign-xray 216). According to ATEL
#140, I. Khamitov et al. detected a possible optical counterpart
(I~20) of this new X-ray transient at R.A.=17h46m15.6s,
Dec=-32o14'01.2'' (vsnet-campaign-xray 217).
R CrB (RA = 15h48m34s.40, Dec = +28d09'23".)7
The object is brightening, but the brightening trend has become
slower (vsnet-campaign-rcb 121, 125).
SN 2003cg (RA = 10h14m15s.97, Dec = +03d28'02".5)
Recently reported observations can be seen in [vsnet-campaign-sn 594].
V348 Sgr (RA = 18h40m19s.94, Dec = -22d54'29".1)
The object has been fading again since early March
(vsnet-campaign-rcb 122).
1RXP J113123+4322.5 (RA = 11h31m22s.426, Dec = +43d22'38".51)
The object is now in a post-superoutburst stage (vsnet-campaign-dn 3563).
SN 2003bv (RA = 07h22m11s.92, Dec = +40d28'01".5)
The CfA team revealed that it is a type II supernova. The
recession velocity deduced from the H-alpha emission peak is about
14000 km/s, which is consistent with the NED value. The SN can be a
very luminous event, or the host galaxy has a peculiarly large
proper motion relative to the Hubble flow. The apparent size of the
galaxy seems large, so the latter possibility should be considered
(vsnet-campaign-sn 597).
Z UMi (RA = 15h02m01s.35, Dec = +83d03'48".7)
The gradual brightening continues (vsnet-campaign-rcb 123).
V854 Cen (RA = 14h34m49s.8, Dec = -39d33'18")
The object is now at faint minimum (vsnet-campaign-rcb 124).
SN 2003bw (RA = 14h57m22s.44, Dec = -19d12'45".9)
The Las Campanas spectrum taken on Mar 31.39 revealed that it was
of type II, at least two months after explosion (vsnet-campaign-sn 593).
eta Car (RA = 10h45m03s.65, Dec = -59d41'03".7)
S. Otero reported that Eta Carinae is not acting too much in the
visual. It stays around V=5.2, although it seems to be brightening
slowly (vsnet-campaign-sdor 30).
V4743 Sgr (RA = 19h01m09s.38, Dec = -22d00'06".2)
D. West reported a decrease in H Alpha emission from the 12 Oct
2002 (vsnet-campaign-nova 1178). He also reported that it has
undergone large changes in the V-Rc color during the coarse of the
outburst (vsnet-campaign-nova 1179, 1181, 1182, 1184, 1185).
Time-series observations on April 5 showed no clear short-term
variation (vsnet-campaign-nova 1183).
BR Lup (RA = 15h35m51s.61, Dec = -40d34'25".4)
An outburst to 14.6mag was reported on April 3 by R. Stubbings.
The object further brightened to 14.0mag on April 6, which indicates
that it is definitely a superoutburst (vsnet-campaign-dn 3571).
The data obtained by G. Bolt on April 7 clearly show fully grown
superhumps with an amplitude of 0.20 mag. The data also show some
hint of quasi-periodic oscillations (QPOs). The superhump period
determined from this single-night run is 0.083 d, which is generally
in agreement with, but seems to be slightly longer than the
previously determined period (vsnet-campaign-dn 3574).
V803 Cen (RA = 13h23m44.5s, Dec = -41d44'30".1)
Reported observations show that it is still in a bright state,
which may be a superoutburst or a oscillatory stage
(vsnet-campaign-dn 3572).
