A rare outburst of an intermediate polar! ----- EX Hya
New SU UMa star? ----- DO Vul

*** Last week news ***

(new targets) 
  EX Hya                  (RA = 12h52m24s.22, Dec = -29d14'56".0)

    R. Stubbings discovered a rare outburst of a intermediate polar, 
  EX Hya at 9.8mag on Nov 4.  The last outburst was recorded in 1998.
  Since the object is an eclipsing system, time-series observations
  are strongly encouraged to reveal the disk structure during the
  outburst of intermediate polars (vsnet-alert 8741).


  DO Vul                  (RA = 19h52m10s.71, Dec = +19d34'42".5)

    P. Schmeer reported that a poorly studied dwarf nova, DO Vul is
  now in a long outburst, which is probably a superoutburst.
  According to his report, the object has been bright (15.3CR mag)
  since Nov 2.  The quiescent magnitude of the object is V=20.73.  
  Its large outburst amplitude also indicates a superoutburst
  (vsnet-campaign 1628). 

  
  VV Pup                  (RA = 08h15m06s.73, Dec = -19d03'16".8)

    R. Stubbings reported that a polar, VV Pup became active and 
  entered in a high state (vsnet-campaign-polar 47).  The high state 
  still continues (vsnet-campaign-polar 48).


  HS 0455+8315            (RA = 05h06m48s.47, Dec = +83d19'23".4)

    S. Shugarov reported a novalike variable, HS 0455+8315 entered 
  in a low state.  It was V=17.2 on Sep 14, then faded to V=21.4 on 
  Nov 2 (vsnet-campaign-nl 177).


(old targets)
  T Leo                   (RA = 11h38m26s.96, Dec = +03d22'08".1)

    The superoutburst is now ongoing (vsnet-outburst 6774).


  V477 Sct                (RA = 18h38m43s, Dec = -12d16'.3)

    K. Nakajima reported V=14.29 on Nov 4 (vsnet-campaign-nova 1775).


  V476 Sct                (RA = 18h32m04s.75, Dec = -06d43'34".3)

    K. Nakajima reported V=14.71 on Nov 4 (vsnet-campaign-nova 1775).
