VSNET Weekly Campaign Summary
*** Last week news ***
(new targets)
Peculiar Variable in Crux (RA = 12h23m16s.2, Dec = -60d22'34")
According to IAUC 8184, V. Tabur discovered a possible nova of
mag 10.2 (CCD) on Aug. 20. On Aug. 21, Tabor reported that it had
brightened about 1 mag. B. Monard had confirmed the brightening,
9.2C on Aug. 21 (vsnet-campaign-nova 1358). The Cerro Tololo
spectrum showed weak H_beta emission with P-Cyg profile, from which
the reporter H. E. Bond suggested that it would be a classical nova
before the maximum. The other reporter M. Della Valle et al.,
however, commented a lack of the typical signatures of classical
novae. They suggested that it would be a flare up of post-AGB star,
like V4332 Sgr, or V838 Mon (vsnet-campaign-nova 1360). W. Liller
reported that the color of the object supports the post-AGB star
scenario (vsnet-campaign-nova 1363). The object is now about 10mag
(vsnet-campaign-nova 1361, 1362).
SN 2003hg (RA = 23h51m24s.13, Dec = +20d06'38".3)
SN 2003hg is hosted by NGC 7771, a barred-spiral galaxy
interacting with a lenticular galaxy NGC 7770. The expected maximum
for typical SN Ia is mag about 14.7, and the object was discovered
with 16.9:C mag, so this SN seems a core-collapse event
(vsnet-campaign-sn 673).
SN 2003hh (RA = 00h00m07s.08, Dec = +08d16'42".3)
SN 2003hh is hosted by UGC 12890, an elliptical galaxy within a
compact cluster. This SN seems to be of type Ia soon after
explosion, which is consistent with the discovery magnitudes
(18.7-18.1 mag) (vsnet-campaign-sn 673).
SN 2003hi (RA = 15h56m33s.80, Dec = +41d53'47".5)
SN 2003hi is hosted by MCG +07-33-16, a spiral galaxy. The
expected maximum for typical SN Ia is mag about 17.5
(vsnet-campaign-sn 674).
SN 2003hj (RA = 15h24m20s.51, Dec = +29d57'11".9)
SN 2003hj is hosted by MCG +05-36-28, a dim galaxy. The expected
maximum for typical SN Ia is mag about 19, but the object was
discovered with 17.5-17.9C mag, so further photometry and spectral
type determination (or the redshift of the host galaxy) is urged
(vsnet-campaign-sn 674).
SN 2003hk (RA = 02h46m25s.69, Dec = +03d36'32".3)
SN 2003hk is hosted by NGC 1085, a spiral galaxy. The expected
maximum for typical SN Ia is mag about 16.6 (vsnet-campaign-sn 674).
SN 2003hl (RA = 01h59m21s.28, Dec = +19d00'14".5)
SN 2003hl is hosted by NGC 772, a nearby spiral galaxy. The
expected maximum for typical SN Ia is mag about 14.7
(vsnet-campaign-sn 675).
SN 2003hm (RA = 02h48m58s.39, Dec = +03d10'07".6)
SN 2003hm is hosted by UGC 2295, a spiral galaxy. The expected
maximum for typical SN Ia is mag about 15.6 (vsnet-campaign-sn 676).
(continuous targets)
V4641 Sgr (RA = 18h19m21s.6, Dec = -25d24'25")
T. Scarmato reported a possible flare to 10.8mag on August 21
(vsnet-campaign-v4641sgr 218, 219).
AM Her (RA = 18h16m13s.4, Dec = +49d52'03".1)
According to the data from D. Starkey and L. Cook, this object
seems to be largely varied superimposed on a fading trend
(vsnet-campaign-polar 27).
