  WX Cet		(RA = 01h17m04s.17, Dec = -17d56'23".0)

    As reported by S. Kerr, WX Cet is in outburst of 11.8mag since 
  June 30.  The last outburst occurred in 1998 November 
  (vsnet-campaign 987).  The Kyoto team confirmed the outburst on 
  July 1 (vsnet-campaign-dn 958), and detected a hints of smooth 
  modulations with an amplitude with 0.1-0.2 mag (vsnet-campaign-dn 961).

 
  V893 Sco		(RA = 16h14m45.26s, Dec = -28d39m30.3s)

    As reported by R. Stubbings and P. Williams, the eclipsing dwarf 
  nova V893 Sco experienced an outburst of 12.7mag on June 27 
  (vsnet-campaign-dn 947).  The bright state lasted for two nights 
  (vsnet-campaign 986), and then seems to be terminated on June 30 
  (vsnet-campaign-dn 959).

  
(continuous targets) 
  V1178 Sco		(RA = 17h57m06s.92, Dec = -32d23'05".0)
  
    W. Liller reported V-magnitudes of this nova of 11.35-11.36mag  
  on June 24 (vsnet-campaign-nova 368), 12.22-12.33 on June 26 
  (vsnet-campaign-nova 371, 378), and 11.70-11.85 on June 27, which 
  imply the presence of short-term variation.  S. Kiyota also 
  reported Ic=10.42 and V=12.25 (vsnet-campaign-nova 370).  K. Kadota 
  provides accurate astrometry (vsnet-campaign-nova 379).  The object 
  is now on the gradual fading trend, and the current magnitude is 
  about 12.2mag (vsnet-campaign-nova 369, 372, 374, 381).
		 	

  RS Oph		(RA = 17h50m13s.56, Dec = -06d42'30".6)

    The bright state continues (vsnet-campaign-nova 380).


  SW UMa		(RA = 08h36m42s.80, Dec = +53d28'38".2)

    The superoutburst continued until June 29 when rapid fading 
  from 10.6mag to 11.5mag was reported (vsnet-campaign-dn 934, 940, 
  952, 955).


  VW CrB		(RA = 16h00m03s.76, Dec = +33d11'14".4)

    The superoutbust continues, and the current magnitude is about 
  15mag (vsnet-campaign-dn 936, 941, 948, 954).  The Kyoto team 
  performed time-series photometry on June 26, and detected a 
  superhump with an amplitude of 0.3mag (vsnet-campaign-dn 943).
  They furthermore reported the object is gradually declining with 
  ~0.1mag/d (vsnet-campaign-dn 960).
 

  GX Cas		(RA = 00h49m01s.46, Dec = +56d52'44".8)

    The superoutburst is still ongoing, and it is about 13.8mag now 
  (vsnet-campaign-dn 935, 942, 951).


  BC UMa		(RA = 11h52m15s.88, Dec = +49d14'42".0)

    The faint outburst lasted unexpectedly longer (vsnet-campaign-dn 
  937, 939), however then showed possible rapid decline since June 27 
  (vsnet-campaign-dn 949, 953).


  IY UMa		(RA = 10h43m56s.87, Dec = +58d07'32".5)

    The superoutburst continued at lease until June 25 
  (vsnet-campaign-dn 938).


  V1548 Aql		(RA = 19h07m28s.42, Dec = +11d44'45".8)

    S. Kiyota's observations indicates a brightening of this nova 
  (vsnet-campaign-nova 370).  The object then again gradually faded 
  (vsnet-campaign-nova 373), and again re-brightened on June 28 
  (vsnet-campaign-nova 376).  The current magnitude is 13.3mag 
  (vsnet-campaign-nova 382).


  AL Com		(RA = 12h32m25s.90, Dec = +14d20'42".5)

    The Kyoto team and Brno team reported that they performed 
  time-series photometry during the last week.  The rebrightening 
  state is still continues (vsnet-campaign-dn 945).


  V445 Pup		(RA = 07h37m56s.88, Dec = -25d56'59".1)

    The bright state seems to be interrupted on July 1 as reported 
  to be 11.2mag by B. Monard (vsnet-campaign-nova 375, 384).

   
  IX Dra		(RA = 18h12m32s.2, Dec = +67d04'41")

    An outburst of 15.5mag was reported by M. Reszelski on June 25 
  (vsnet-campaign-dn 950).


  CR Boo		(RA = 13h48m55s.42, Dec = +07d57'30".3)

    The recent activity is summarized in [vsnet-campaign-dn 956].

 
  V446 Her		(RA = 18h57m21s.51, Dec = +13d14'27".3)

    D. Nogami reported that E. Pablenko noticed him that the object 
  is in intermediate brightness at mag~15.9 on July 1, which means 
  that V446 Her is now ascending or descending (vsnet-campaign-dn 957, 
  vsnet-campaign-nova 383, vsnet-campaign 988).
