VSNET Weekly Campaign Summary
*** Last week news ***
(new targets)
XTE J0929-314 (RA = 09h29m20s.16, Dec = -31d23'02".7)
R. Remillard reported: The RXTE All-Sky Monitor detected a
faint X-ray transient. The average flux was 15 +- 2 mCrab
during 2002 April 13-18, inclusive, rising to 20 +- 2 mCrab
(April 19-24), and 26 +- 1 mCrab (April 25-30). The error
circle does not contain any noteworthy sources in the Simbad
catalogs. The ASM hardness ratios suggest an X-ray spectrum
similar to transients associated with weakly magnetic neutron
stars or some black hole systems (vsnet-campaign 1308,
vsnet-campaign-xray 136). The optical counterpart was reported
in IAUC 7889 by Greenhill et al.. P. Cacella reported V=18.3
on May 1 (vsnet-campaign-xray 137, 138, 139).
SN 2002cp (RA = 09h59m35s.95, Dec = +35d23'57".4)
The LOTOSS team discovered SN 2002cp on images taken on April
28.2 (17.9mag) and 30.2 (17.7mag). SN 2002cp is located about
64" west and 23" north of the nucleus of a face-on open spiral
galaxy NGC 3074. The expected maximum for typical SN Ia is mag
about 15.9. NGC 3074 has produced SN 1965N, whose maximum was
pg = 16.2 (vsnet-campaign-sn 417).
SN 2002cr (RA = 14h06m37s.59, Dec = -05d26'21".9)
A nearby SN was discovered by R. Kushida. It seems to be
rising, and is expected to reach mag 14 if it is of type Ia.
SN 2002cr was discovered on May 1.701 at mag 16.5 and confirmed
on the next night at mag 16.2. The position is about 40" east
and 50" north of the center of a face-on spiral galaxy NGC 5468.
Another SN 1999cp was appeared on the same galaxy. It was of
type Ia, and its maximum was mag around 14.0 (vsnet-campaign-sn 418).

2347). The rapid fading from the outburst was reported on May 4
(vsnet-campaign-dn 2352, 2357).
DI UMa (RA = 09h12m22s.16, Dec = +50d49'39".1)

2340).
EK TrA (RA = 15h14m00s.19, Dec = -65d06'17".1)
As reported by R. Stubbings on May 4, the SU UMa-type dwarf
nova EK TrA experienced an outburst (12.9mag). The last reported
outburst was in 2001 June (vsnet-campaign-dn 2354).
The object rapidly faded (vsnet-campaign-dn 2358).
FG Ser (RA = 18h15m07s.06, Dec = -00d18'53".0)
An observation reported by H. Itoh on May 2 shows that the
object has been very faint (13.4mag). It may be in eclipse
(vsnet-campaign-symbio 14).
HL CMa (RA = 06h45m17s.0, Dec = -16d51'35")
The possible standstill still continues (vsnet-campaign-dn 2350).

The object again showed an outburst (14.3mag) on May 4.
The object was still in outburst on May 5 (vsnet-campaign-v2051oph
6, 7).
IX Dra (RA = 18h12m32s.2, Dec = +67d04'41")

The object experienced a new outburst (14.0mag, 13.9mag) on
May 1, as reported by T. Kinnunen and P. A. Dubovsky
(vsnet-campaign-dn 2341, 2343). The object faded to 14.5mag
on May 2 (vsnet-campaign-dn 2351).
V838 Mon (RA = 07h04m04s.816, Dec = -03d50'50".94)
The object has been further faded, and it is now very red and
fainter than 13.9mag (vsnet-campaign-v838mon 349, 350, 351, 352,
354, 355, 357, 358, 359, 360, 361, 365). A. Henden reported that
the light echo has remained about the same diameter for the past
month (vsnet-campaign-v838mon 354). M. Orio performed R, V, and
narrow fileters imaging and reported that the contour of the shell
("light echo") is irregular, and it is a reflection rather than
an ionization nebula (vsnet-campaign-v838mon 353, 364). In the
echo, HST detected approximately circular concentric rings or arcs,
and several highly structured, non-concentric filamentary features
(vsnet-campaign-v838mon 363). U. Munari provided a good short
review on the light echo around V838 Mon in [vsnet-campaign-v838mon 362].
An emission line of H-alpha appeared in the spectrum taken by
M. Fujii on May 1 (vsnet-campaign-v838mon 356).
V504 Cen (RA = 14h12m49s.36, Dec = -40d21'02".2)
The object is still very faint, as shown by observations by
R. Stubbings (vsnet-campaign-nl 81).
