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).
