Possible Nova in Cen!

*** Last week news ***

(new targets)
  Nova Cen 2005           (RA = 13h20m49s.8, Dec = -62d37'50".9) 

    W. Liller reported the discovery of a possible nova in Cen.  Its
  approximate magnitude was 8.5 at Sept. 1.031 UT.  Nothing was seen
  brighter than mag 11.0 on Aug. 12.050 (vsnet-campaign-nova 1745).


  Possible Nova in M31     (RA = 00h38m49s.52 Dec = +40d19'54".1)

    R. Quimby et al., reported in Atel #600 that they discovered a
  possible nova in M31 using the ROTSE-IIIb system.  The object was
  about 18.0 and 16.5mag on Sep 1.23 and 2.23, respectively
  (vsnet-campaign-nova 1747).  Based on multi-color observations by
  H. Maehara, T. Kato commented that the object is a slightly reddened
  M31 object, i.e., likely a nova (vsnet-campaign-nova 1748). 


  V369 Peg                 (RA = 23h03m41s.81, Dec = +17d17'55".5)

    J. Pietz reported a superoutburst of V369 Peg with detecting
  superhumps on Aug. 28 (vsnet-campaign-dn 4514).


  HX Peg                   (RA = 23h40m23s.70, Dec = +12d37'41".7)

    Based on recent observations reported to VSNET, T. Kato found that
  HX Peg seems to have entered a standstill this August
  (vsnet-campaign-dn 4518).
 

  TY Psc                   (RA = 01h25m36s.87, Dec = +32d23'05".)3
 
    TY Psc is now in superoutburst (vsnet-campaign-dn 4520).


  FO And                   (RA = 01h15m32s.14, Dec = +37d37'35".5)

    FO And is likely undergoing a superoutburst (vsnet-campaign-dn
  4521). 


  ROTSE3 J214850-020622.2  (RA = 21h48m50s, Dec = -02d06'22".2)

    According to Atel #603, the ROTSE team reported the discovery of a
  possible cataclysmic variable.  The object was first detected in
  unfiltered CCD images (17.2mag) taken on September 2.32
  (vsnet-campaign-dn 4523).


(old targets)
  Var Vul 05               (RA = 19h59m51s.29, Dec = +22d42'32".3)
  (= OT_J195951.3+224232)

    According to cvnet, T. Vanmunster refined the superhump period to
  be 0.0590 +/- 0.0002d (vsnet-campaign-dn 4515).  The outburst
  amplitude is around 8 mag, still close to that of WZ Sge
  (vsnet-campaign-dn 4517, 4516).  The outburst is now ongoing.  The
  long duration of the superoutburst further support the WZ Sge-type
  classification (vsnet-campaign-dn 4522).


  RR Tau                   (RA = 05h39m30s.53, Dec = +26d22'26".3)

    The object is still in a faint state (vsnet-campaign-orion 102).


  V5116 Sgr                (RA = 18h17m50s.77, Dec = -30d26'31".2)

    The nova is now fading.  The latest observation shows V=12.37 (by
    K. Nakajima; vsnet-campaign-nova 1744, 1746).


  V1663 Aql                (RA = 19h05m12s.50, Dec = +05d14'12".0)

    The nova is now at 16th mag in V-band (vsnet-campaign-nova 1744,
  1746). 


  V1188 Sco                (RA = 17h44m21s.59, Dec = -34d16'35".7)
 
    K. Nakajima reported V=13.17 on Sep 2 (vsnet-campaign-nova 1746).


  V660 Her                 (RA = 17h42m07s.3, Dec = +23d47'37".3)

    The current superoutburst of V660 Her seems to be enduring
  (lasting more than 10 days), as indicated by recent observations
  (vsnet-campaign-dn 4519).
