*** Headlines ***
New eclipsing SU UMa-type dwarf nova! ----- SDSSJ170213.26+322954.1
*** Last week news ***
(new targets)
SDSSJ170213.26+322954.1 (RA = 17h02m13s.26, Dec = +32d29'54".1)
P. Schmeer discovered the first outburst of an eclipsing CV,
SDSSJ170213.26+322954.1 on Sep 30 (13.7CR) and Oct 1 (13.9CR).
T. Vanmunster confirmed the outburst on Oct. 3 at mag 14.2.
The object is a high-inclination CV that shows deep eclipses with a
period of 2.5 hours (P. Szkody et al.) (vsnet-campaign 1624).
A. Oksanen performed time-series photometry and reported superhumps
with 0.3mag amplitudes. He reported a superhump period of 0.1056 d
and an orbital period of 0.1001 d. The object was confirmed to be
an eclipsing SU UMa-type dwarf nova, which is in the period gap of
CVs (vsnet-campaign-dn 4557).
NSV14652 (RA = 23h36m19s, Dec = +28d03'.3)
P. Schmeer reported an outburst of NSV14652 from observations on
Sep 30 at 15.9CR mag. The object soon faded to 16.9CR mag on Oct 1
(vsnet-alert 8708). J. Pietz reported that the last supermaximum of
this dwarf nova occurred at 02-15 Sep 2004. During that
superoutburst, superhump period was around 0.0814 d
(vsnet-campaign-dn 4553). J. Pietz furthermore reported that the
object was fainter than 17.0C on Oct 5, but brightened to 15.6C on
Oct 6 (vsnet-campaign-dn 4556).
1RXS_J053234.9+624755 (RA = 05h32m33s.87, Dec = +62d47'52".1)
W. MacDonald reported an outburst of this SU UMa-type dwarf nova
on Oct 3 at 13.00V (vsnet-campaign-dn 4554).
V630 Cyg (RA = 21h34m59s.21, Dec = +40d40'18".5)
W. MacDonald reported an outburst of this SU UMa-type dwarf nova
on Oct 2 (15.27V) and Oct 3 (15.61V) (vsnet-campaign-dn 4555).
(old targets)
V476 Sct (RA = 18h32m04s.75, Dec = -06d43'34".3)
(= Nova Sct 2005)
According to M. Fujii, Nova Sct 2005 = V476 Sct is shown to be a
typical Fe II-type nova based on spectra which he took on Oct 6.
The FWHM of Halpha is 1700 km/s. [O I] line is strong. The nova
also shows a substantial reddening, as suggested from photometry
(vsnet-campaign-nova 1765). S. Kiyota reported V=11.66 on Oct 2
(vsnet-campaign-nova 1764).
FN Sgr (RA = 18h53m54s.79, Dec = -18d59'40".8)
P. F. Williams reported that FN Sgr was in an eclipse from his
observations on Sep 30 and Oct 1 (vsnet-campaign-symbio 112, 113).
TT Ari (RA = 02h06m53s.09, Dec = +15d17'43".0)
According to H. Maehaea, TT Ari had further faded to mag 11.6 (CCD
unfiltered) again on Sep. 30. No superhumps were detected in a CCD
photometric run (vsnet-campaign-nl 176, vsnet-campaign 1625).
