VSNET Weekly Campaign Summary
*** Last week news ***
(new targets)
Possible Nova Sct 2003 (RA = 18h49m37s.62, Dec = -09d33'50".3)
A bright nova was discovered by H. Nishimura on August 28.577 with
8.5 mag. The eruption was also detected in the ASAS-3
(vsnet-campaign-nova 1364). The nova was soon confirmed by
M. Linnolt and R. Stubbings on August 30 (vsnet-campaign-nova 1365,
1368). W. Liller reported his pre-discovery observation of 9.8mag
on August 26 (vsnet-campaign-nova 1369, 1370). Multi-color
observations by K. Nakajima showed that the colors are not
inconsistent with a moderately reddened nova. T. Kato commented
that the object is likely a moderately remote object reaching its
maximum around the discovery date (vsnet-campaign-nova 1367). A
nearby 16th mag star is unlikely the progenitor of the nova.
H. Yamaoka reported a possible progenitor of a r1mag=17.67mag star
in USNO-B1.0 catalog (vsnet-campaign-nova 1373). W. Liller took a
spectrum showing a very narrow and weak H-alpha emission
(vsnet-campaign-nova 1376). M. Fujii also performed spectroscopy
and confirmed the emission lines (vsnet-campaign-nova 1378).
U. Munari reported that the Balmer line profiles show a weak
absorption component blushifted by 500 km/sec and a second emission
peak red shifted by 650 km/sec with respect to the main emission
line (vsnet-campaign-nova 1379). M. Gavin reported that the
spectrum taken by him did not show the classic nova spectrum but
resembles V838Mon (vsnet-campaign-nova 1380). After a temporary
gradual fading, the object rebrightened on September 1
(vsnet-campaign-nova 1375, 1371, 1374, 1377, 1381, 1382).
SN 2003hn (RA = 03h44m36s.1, Dec = -44d37'49")
A bright SN 2003hn was discovered on Aug. 25.70 UT at visual mag
14.1 by R. Evans. On Aug. 5, there was no object brighter than
15.5. The position of the object is about 47" east and 53" north of
the nucleus of NGC 1448, a nearby spiral galaxy. It is superimposed
on the outer disk region, and there is a bright H II region near the
SN. NGC 1448 has produced two other SNe. SN II 1983S was
discovered (also by R. Evans) at mag 14.5. SN Ia 2001el reached mag
about 12.5. SN 2003hn seems not in a rapid rising phase, and its
color is not very blue, which may suggest that it is a somewhat
young gravitational-collapse event. The spectrum obtained by the
ANU group revealed that it was a type II SN about two weeks after
explosion (vsnet-campaign-sn 678).
SN 2003ho (RA = 21h06m30s.56, Dec = -48d07'29".9)
SN 2003ho is hosted by ESO 235-G58, an open barred-spiral galaxy.
The expected maximum for typical SN Ia is mag about 15.5. The
object was discovered with about 18.6mag, so it is possibly an old
SN or/and a collapsing event (vsnet-campaign-sn 677, 679).
RZ Psc (RA = 01h09m40s.07, Dec = +27d57'28".0)
P. Schmeer reported that RZ Psc is fading (vsnet-campaign-orion 57).
SN 2003hp (RA = 17h40m18s.69, Dec = +51d01'41".3)
SN 2003hp is hosted by UGC 10942, a barred-spiral galaxy
interacting with MCG +09-29-016. The expected maximum for typical
SN Ia is mag about 16.4 (vsnet-campaign-sn 680, 681). The spectrum
taken by the UCB team on August 28 showed that it is probably a SN
with a blue continuum, but certain classification is uncertain. The
recession velocity is measured as 15000 km/s, which differs from the
NED value (6378 km/s) (vsnet-campaign-sn 682).
(continuous targets)
SN 2003hf (RA = 16h50m48s.38, Dec = +45d24'01".8)
The spectrum taken by the UCB team on August 28 showed that it was
probably type II SN, but has very blue continuum for 2 weeks after
explosion (vsnet-campaign-sn 682).
SN 2003hg (RA = 23h51m24s.13, Dec = +20d06'38".3)
The Asiago group revealed that it was a type-II SN shortly after
explosion on Aug. 22.48 spectrum. It seems to be highly reddened by
the interstellar matter (vsnet-campaign-sn 679).
SN 2003hh (RA = 00h00m07s.08, Dec = +08d16'42".3)
The VLT spectrum (on Aug. 20) revealed that it was a subluminous
type Ia SN before maximum. It is reddened by the interstellar
medium in the host galaxy (vsnet-campaign-sn 679).
SN 2003hi (RA = 15h56m33s.80, Dec = +41d53'47".5)
The spectrum taken by the UCB team on August 28 showed that it is
a normal type II SN (vsnet-campaign-sn 682).
SN 2003hj (RA = 15h24m20s.51, Dec = +29d57'11".9)
The spectrum taken by the UCB team on August 28 showed that it was
a SN Ia 2 weeks after maximum. The recession velocity of the host
galaxy was measured as v_r = 23000 km/s (vsnet-campaign-sn 682).
SN 2003hk (RA = 02h46m25s.69, Dec = +03d36'32".3)
The spectrum taken by the UCB team on August 28 showed that it is
a normal type II SN (vsnet-campaign-sn 682).
SN 2003hl (RA = 01h59m21s.28, Dec = +19d00'14".5)
The spectrum taken by the UCB team on August 28 showed that it is
a normal type II SN (vsnet-campaign-sn 682).
SN 2003gv (RA = 01h08m53s.18, Dec = +32d05'59".3)
The spectrum taken by the UCB team on August 28 showed that it is
a normal type II SN (vsnet-campaign-sn 682).
SN 2003hm (RA = 02h48m58s.39, Dec = +03d10'07".6)
The spectrum taken by the UCB team on August 28 showed that it was
a type Ia SN, about 2 months after maximum (vsnet-campaign-sn 682).
SN 2003he (RA = 23h58m57s.05, Dec = -02d14'53".1)
The spectrum taken by the UCB team on August 28 showed that it is
probably a SN, but certain type is uncertain. It has red continuum,
which is atypical for SN (vsnet-campaign-sn 682).
SN 2003hc (RA = 02h31m42s.04, Dec = +39d22'05".5)
The spectrum taken by the UCB team on August 28 showed that it is
a normal type II SN (vsnet-campaign-sn 682).
SN 2003gw (RA = 05h11m47s.68, Dec = +67d29'22".2)
The spectrum taken by the UCB team on August 28 showed that it is
probably a type II SN, but the width of H_alpha is rather small
(2000 km/s) (vsnet-campaign-sn 682).
