[vsnet-campaign 1320] VSNET Weekly Campaign Summary
VSNET Weekly Campaign Summary
*** Last week news ***
(new targets)
KL Dra (RA = 19h24m38s.14, Dec = +59d41'47".1)
M. Wood informed that the helium dwarf nova KL Dra appeared
to be undergoing a superoutburst. The object was observed in
outburst in 2001 July-August. T. Kato reported that the supercycle
could be around 300 d or its 1/N (vsnet-campaign-dn 2555).
T. Kato reported a confirmation of the outburst by K. Matsumoto
on June 14 (vsnet-campaign-dn 2560). G. Masi and U. Tagliaferri
also confirmed and observed the object, and reported R=16.2 on
June 16 (vsnet-campaign-dn 2563). T. Kato reported the detection
of superhumps with amplitudes of 0.1-0.2mag on June 16
(vsnet-campaign-dn 2565, 2572). G. Masi reported a significant
fading (0.05mag during 3+ hours) during their run on June 16
(vsnet-campaign-dn 2574, 2575). The fading was confirmed by
observations at Kyoto (vsnet-campaign-dn 2577). Follow-up
observations are still highly recommended.
EP Car (RA = 10h28m23s.21, Dec = -58d57'58".6)
As reported by R. Stubbings on June 13, this SU UMa candidate
experienced an outburst to 14.5mag. The last outburst was
reported in 2001 April (vsnet-campaign-dn 2556). The outburst
still continued on June 15 without rapid fading
(vsnet-campaign-dn 2568).
FW CMa (RA = 07h24m40s.11, Dec = -16d12'05".2)
S. Otero reported a correct amplitude of this GCAS-type
variable of V= 5.00 - 5.38 (vsnet-campaign-be 188).
SN 2002dj (RA = 13h13m00s.34, Dec = -19d31'08".7)
The host galaxy of SN 2002dj is NGC 5018, an elliptical galaxy
affected by some Galactic extinction (A_V = 0.317). The position
of SN is about 9" west and 3" south of the nucleus of NGC 5018.
The expected maximum of typical SN Ia is mag about 14.8
(vsnet-campaign-sn 438). IAUC 7919 informed that the Padova team
took a spectrum of SN 2002dj on June 14.15 UT at La Silla, which
shows that it is of type Ia well before (~10 days) maximum light
(vsnet-campaign-sn 439).
V348 Sgr (RA = 18h40m19s.94, Dec = -22d54'29".1)
R. Stubbings detected a brightening to 14.0mag of this object
on June 13 (vsnet-campaign-rcb 42).
CAL 86 (RA = 05h46m18s.2, Dec = -68d35'37")
According to Schmidtke et al., the X-ray source CAL 86 in the
direction of the LMC is confirmed to be a short-period cataclysmic
variable with a short period (0.0660 d). The object reaches mag
14 at maximum (amplitude 5 mag). The light curve presented is
typical of an SU UMa-type superoutburst. Please monitor this object,
and make time-series photometry when a new outburst is detected
(vsnet-campaign-dn 2561).
AM Her (RA = 18h16m13s.4, Dec = +49d52'03".1)
The object seems to pass the deep minimum and to be possibly
brightening now (vsnet-campaign-polar 4).
eta Car (RA = 10h45m03s.65, Dec = -59d41'03".7)
S. Otero commented on a possibility that eta Car will again
brighten and become brighter than 5.0mag in the end of this
August (vsnet-campaign-sdor 16). Close monitoring is encouraged.
Suspect object near NGC 6946
A suspected new object was reported near NGC 6946 on June 13,
however, no bright object was confirmed later
(vsnet-campaign-unknown 72, 73, 75, 71, 76, 74, 77, 78, 79,
80, 81, 82, 83, 84, 85, 86).
(continuous targets)
V877 Ara (RA = 17h16m58s.80, Dec = -65d32'58".6)
T. Kato reported a superhump period of 0.08458(3) d using
the light curves obtained by S. Walker, G. Bolt and R. Santallo
(vsnet-campaign-dn 2546, 2548). Superhump periods were variable,
and the inferred period change was reported to be an order of
-2x10^(-4), which is the largest period change ever observed in
long-period SU UMa-type systems (vsnet-campaign-dn 2566).
The superoutburst continues (vsnet-campaign-dn 2545, 2550, 2557,
2562, 2571, 2576).
V729 Sgr (RA = 19h16m49s.15, Dec = -26d14'33".2)
The fading from the outburst was observed on June 11
(vsnet-campaign-dn 2553).
V Sge (RA = 20h20m14s.75, Dec = +21d06'09".0)
The object further brightened (vsnet-campaign-nl 87).
AH Her (RA = 16h44m09s.99, Dec = +25d15'02".1)
The standstill was terminated (vsnet-campaign-dn 2573).
UY Cen (RA = 13h16m31s.90, Dec = -44d42'14".9)
S. Otero commented on different color response and observing
technics, which should be noticed when observers estimate magnitudes
of the object (vsnet-campaign-rcb 40, 41).
SN 2002dh (RA = 15h24m49s.35, Dec = -22d45'57".7)
According to IAUC 7917, this SN turned out to be of type II.
The recession velocity of the host galaxy is measured as 3900 km/s,
which indicate that SN 2002dh has a normal luminosity as of SN II
(vsnet-campaign-sn 437).
V359 Cen (RA = 11h58m15s.29, Dec = -41d46'07".9)
The superoutburst finished (vsnet-campaign-dn 2559).
QW Ser (RA = 15h26m13s.99, Dec = +08d18'03".8)
T. Kato reported that the light curve on June 9 showed the
remarkable evolution of sub-structures of superhumps. The most
prominent feature was likely "late superhumps" between superhump
maxima (vsnet-campaign-dn 2544). The object has faded from
the superoutburst since June 13 (vsnet-campaign-dn 2552, 2558).
Z Cha (RA = 08h07m16s.29, Dec = -76d32'20".9)
The fading from the superoutburst was confirmed on June 15
(vsnet-campaign-dn 2551, 2569).
V4641 Sgr (RA = 18h19m21s.6, Dec = -25d24'25")
The object has remained at quiescent level, but possibly still
active (vsnet-campaign-v4641sgr 93, 94, 96). The observation on
June 13 at Ouda shows a relatively calm light curve
(vsnet-campaign-v4641sgr 95).
delta Sco (RA = 16h00m19s.9, Dec = -22d37'17")
S. Otero reported 1.73mag on June 15 (vsnet-campaign-be 189, 190).
V803 Cen (RA = 13h23m44.5s, Dec = -41d44'30".1)
The object rebrightened to 13.2mag on June 15 (vsnet-campaign-dn
2554, 2567).
CR Boo (RA = 13h48m55s.42, Dec = +07d57'30".3)
The object is still bright at about 14.0mag (vsnet-campaign-dn 2570).
V2051 Oph (RA = 17h08m19.1s, Dec = -25d48m31.1s)
The object is reported to be still rather active
(vsnet-campaign-v2051oph 22, 23).
RS Oph (RA = 17h50m13s.56, Dec = -06d42'30".6)
The object was reported to further brighten (vsnet-campaign-nova
938, vsnet-campaign-symbio 17).
omega CMa (RA = 07h14m48s.70, Dec = -26d46'22".1)
S. Otero reported that the object further brightened over
3.6mag, breaking probably its own record (vsnet-campaign-be 187).
