VSNET Weekly Campaign Summary
*** Last week news ***
(new targets)
XRF 020903 (RA = 22h48m42s.34, Dec = -20d46'09".3)
A. M. Soderberg et al. reported in GCN 1554 that they discovered
a possible optical counterpart of X-ray flash of 3 September 2002.
Their additional observations revealed a brightening of the object,
which they proposed to be a supernova associated with this XRF. If
the optical transient is indeed associated with XRF020903, it is the
first known optical afterglow of an XRF, and may be the most nearby
cosmological high energy transient known yet (vsnet-campaign-sn 479).
GRB 021004 (RA = 00h26m54s.689, Dec = +18d55'41".3)
B. Monard reported his observations of the optical afterglow of
GRB 021004; 17.9CR mag on October 4.809 and at 18.9CR mag on 5.824
(vsnet-campaign-grb 9, 10, 11, 12).
Var73 Dra (RA = 20h23m38s.193, Dec = +64h36m26s.91)
The Kyoto observations (observers: M. Uemura and R. Ishioka) have
detected a bright outburst of Var73 Dra, a long-period (probably in
the period gap) SU UMa-type dwarf nova recently discovered. The
object was rising on October 4, and likely attained its maximum
around October 9-10. The maximum was around 15.0 or possibly
brighter. The object has been confirmed to be still bright on
October 11. Preliminary analysis of the recent data shows
variations of 0.2-0.3 mag, which are likely superhumps
(vsnet-campaign-dn 2888, 2898).
TY Psc (RA = 01h25m36s.87, Dec = +32d23'05".3)
The superoutburst, which was detected on September 27, is still
ongoing. It is now reported to be V~11.5 (vsnet-campaign-dn 2876,
2881, 2871, 2870, 2884, 2887).
RZ Sge (RA = 20h03m18s.49, Dec = +17d02'52".6)
A superoutburst (12.5mag) was detected on September 30
(vsnet-campaign-dn 2877). The superoutburst still continues
(vsnet-campaign-dn 2880, 2885).
SN 2002fs (RA = 22h54m00s.88, Dec = +14d39'24".5)
SN 2002fs is located on 3" due east of an apparent host anonymous
spiral galaxy. A spectrum taken on Sept. 28 with the Baade 6.5-m
telescope revealed that it is type Ia SN a few days past maximum
light. The redshift of the host galaxy is measured as 0.038
(vsnet-campaign-sn 481).
SN 2002ft (RA = 23h15m45s.82, Dec = -16d55'35".2)
SN 2002ft is a type Ia SN soon after maximum on Sept. 28
(vsnet-campaign-sn 481).
SN 2002fu (RA = 22h09m55s.99, Dec = +12d05'06".6)
SN 2002fu is a distant type II SN. The host galaxy is anonymous
spiral one. A foreground star (USNO-A2.0 rmag = 19.2) exist quite
near to SN (about 5" due north of SN)(vsnet-campaign-sn 481).
AG Dra (RA = 16h01m40s.98, Dec = +66d48'10".3)
The object was reported to brightened to 9th mag since the end of
September (vsnet-campaign-symbio 33, 35).
HX Peg (RA = 23h40m23s.37, Dec = +12d37'44".0)
The object is now in standstill (vsnet-campaign-dn 2886, 2896).
(continuous targets)
V729 Sgr (RA = 19h16m49s.15, Dec = -26d14'33".2)
An outburst of 14.4mag was detected on September 30 by
R. Stubbings (vsnet-campaign-dn 2878).
AH Her (RA = 16h44m09s.99, Dec = +25d15'02".1)
The object brightened from standstill (vsnet-campaign-dn 2882).
V348 Sgr (RA = 18h40m19s.94, Dec = -22d54'29".1)
The object is brightening since the end of September
(vsnet-campaign-rcb 72).
V2540 Oph (RA = 17h37m34s.36, Dec = -16d23'18".4)
The object is now slowly fading (vsnet-campaign-nova 1080).
BL Lac (RA = 22h02m42s.86, Dec = +42d16'37".6)
The active phase continues (vsnet-campaign-blazar 275, 276).
UW Pic (RA = 05h31m35s.596, Dec = -46d24'05".54)
About the identification of UW Pic, K. Reinsch commented: The
optical counterpart (later designated UW Pic) of the ROSAT All-Sky
Survey X-ray source RX J0531.5-4624 has been spectroscopically
identified as the most northern component of the apparent stellar
triple visible within the 3-sigma error circle of the X-ray position
(vsnet-campaign-polar 19, 20).
SDSSp J173008.38+624754.7 (RA = 17h30m08s.38, Dec = +62d47'54".7)
The object returned to the quiescent level (vsnet-campaign-dn 2873).
CH UMa (RA = 10h07m00s.90, Dec = +67d32'45".0)
The outburst continues (vsnet-campaign-dn 2883, 2869).
MisV1147 (RA = 22h54m03s.78, Dec = +58d54'02".1)
The object was reported to be faint again (<15.6mag) on September
29 as reported by M. Poxon (vsnet-campaign-unknown 106, 107). The
faint state was confirmed on September 29 - October 2
(vsnet-campaign-unknown 108, 109, 110, 111). The object then
brightened to 13.7mag on October 5 (vsnet-campaign-unknown 112, 113).
KV Dra (RA = 14h50m38.4s, Dec = +64d03m29s)
J. Pietz reported that the humps, which were observed during the
last superoutburst, looks more dip-like. T. Kato commented that the
evolution of the superhumps resembles that of V1028 Cyg, as has been
expected from the similarity in their orbital periods and outburst
properties (vsnet-campaign-dn 2875).
V4743 Sgr (RA = 19h01m09s.38, Dec = -22d00'06".2)
The fading continues (vsnet-campaign-nova 1086, 1083, 1089).
The fading rate became somewhat smaller (vsnet-campaign-nova 1091,
1093).
V4742 Sgr (RA = 18h02m21s.864, Dec = -25d20'32".22)
The object is now fading. The fading rate became somewhat smaller
(vsnet-campaign-nova 1088, 1077, 1082, 1079, 1084, 1087, 1090, 1093).
V838 Mon (RA = 07h04m04s.816, Dec = -03d50'50".94)
The object was reported V=13.60 on October 9 by K. Nakajima
(vsnet-campaign-v838mon 386, 388).
V877 Ara (RA = 17h16m58s.80, Dec = -65d32'58".6)
An outburst of 14.3mag was reported by R. Stubbings on October 11
(vsnet-campaign-dn 2891).
V854 Cen (RA = 14h34m49s.8, Dec = -39d33'18")
S. Otero reported that V854 Cen is fading more rapidly than usual
from a long lasting maximum of the last pulsation cycle. The object
was reported to be about 7.5mag on October 5 (vsnet-campaign-rcb 73).
ES Aql (RA = 19h32m21s.58, Dec = -00d11'31".2)
The fading continues. Some observations reported it to be at 14th
mag (vsnet-campaign-rcb 71).
