VSNET Weekly Campaign Summary
 
*** Last week news ***

(new targets)
  Nova Sco 2001		(RA = 17h57m06s.98, Dec = -32d23'05".0)
  = V1178 Sco			

    K. Haseda discovered and reported a possible nova of 10th mag 
  on June 20.  The object has already been bright at least since 
  May 13 according to his previous observations.  K. Kadota commented 
  that there was no object brighter than mag 14 on a CCD image taken 
  on 2000 Feb. 24.  T. Kato reported there is no known variable star 
  at this position and a search on 2MASS and MSX5C catalogs has not 
  revealed any likely counterpart (vsnet-campaign-nova 350).  
  K. Takamizawa's observations revealed the eruption began between 
  April 26 and May 12 (vsnet-campaign-nova 351).  K. Kanatsu's 
  observations are also consistent with the above pre-discovery 
  observations (vsnet-campaign-nova 358).  On June 21, W. Liller 
  reported a possible H-alpha strong emission line in the low 
  resolution spectrum (vsnet-campaign-nova 353, 354, 355).  W. Liller 
  also reported red magnitudes from February to June and short-term 
  oscillations in June 22 observations (vsnet-campaign-nova 357, 360).  
  According to IAUC 7650, this presumable nova has been given a GCVS 
  name of V1178 Sco (vsnet-campaign-nova 364).  On June 24, M. Fujii 
  took a spectrum which provides a firm evidence that V1178 Cyg is a 
  genuine nova.  The outburst is still ongoing, and the current 
  magnitude is about 10.8mag (vsnet-campaign-nova 356, 365).


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

    As reported by M. Simonsen on June 24, the recurrent nova 
  RS Oph is relatively bright and active at about 11.0-11.3 
  (vsnet-campaign-nova 367).

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

    As reported by P. Schmeer on June 22, SW UMa is now in outburst 
  at 11.6mag (vsnet-campaign-dn 924, 925).  J. Gunther reported 
  the bright state remains on 24 June, which indicates the current 
  outburst seems to be a superoutburst (vsnet-campaign-dn 927).
  The superoutburst is still ongoing and the current magnitude is 
  about 10.5mag (vsnet-campaign-dn 928, 933).

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

    The SU UMa-type dwarf nova VW CrB is possibly undergoing a 
  superoutburst as reported by M. Simonsen at 14.0mag on June 18 
  (vsnet-campaign-dn 919).  The outburst is still ongoing and 
  the current outburst is probably a genuine superoutburst
  (vsnet-campaign-dn 923).

  
  TK5 Lyr		(RA = 19h17m26s.5, Dec = +37d10'41")

    T. Vanmunster reported an outburst of TK5 Lyr at 15.2mag on 
  June 18 (vsnet-alert 6001).  The outburst continues on June 19 
  (vsnet-campaign-dn 921).


  mu Cen		(RA = 13h49m37s.09, Dec = -42d28'24".7)

    S. Otero reported a brightening of mu Cen from 3.50mag on June 
  6 to 3.28mag on June 21 (vsnet-campaign-be 136).


  W Com			(RA = 12h21m31.5s, Dec = +28d13m57.6s)

    C. Gino reported W Com is rising and R=13.8mag on June 20 
  (vsnet-campaign-blazar 207).


  V1028 Cyg		(RA = 20h00m52.13s, Dec = +56d56'22.3")

    As reported by J. Pietz on June 24, the SU UMa-type dwarf nova, 
  V1028 Cyg is in outburst at 15.4mag (vsnet-campaign-dn 926).
  It has already rapidly faded (vsnet-campaign-dn 930).


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

    The SU UMa-type dwarf nova, GX Cas is now in outburst at 13.6mag 
  as reported by M. Reszelski on June 24 (vsnet-campaign-dn 931).
 

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

    As reported by M. Simonsen on June 25, the SU UMa-type dwarf 
  nova, BC UMa shows an outburst.  Although it may be just a normal 
  outburst, the present outburst may be a rare, faint superoutburst 
  (vsnet-campaign 984).  The current magnitude is about 13.2mag 
  (vsnet-campaign-dn 932).


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

    The superoutburst continues (vsnet-campaign-dn 916, 922, 929).


  BL Lac		(RA = 22h02m42.86s, Dec = +42d16'37.6")

    The outburst is still continues (vsnet-campaign-blazar 206).


  QW Ser		(RA = 15h26m13s.99, Dec = +08d18'03".8)

    A rapid fading from the outburst was reported on June 18 
  (vsnet-campaign-dn 917, 920).


  V1548 Aql		(RA = 19h07m28s.42, Dec = +11d44'45".8)
 
    The gradual brightening still continues (vsnet-campaign-nova 352).
  It may be near the second maximum (vsnet-campaign-nova 363).


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

    The re-brightening is still ongoing (vsnet-campaign-dn 915).


  (SN?) 2001bn		(RA = 14h30m39s.53, Dec = -02d06'00".6)

    A. Henden reported that the brightness of this possible SN 
  remains at about V=19.7mag, which supports it is not a genuine 
  SN (vsnet-campaign 981).

    
*** Future schedule ***

  V446 Her campaign until September
    conducted by Matthias Schreiber, Boris Gaensicke, and Daisaku Nogami

    As performed during the last summer, they again call for observations 
  of V446 Her to study its peculiar outburst activity, a part of which 
  is indicated from the results during the last summer.
    The followings are from [vsnet-campaign-dn 918] by D. Nogami
  "Our aim is again to obtain a *good* contiguous light curve of V446 Her
   that covers 2-3 outbursts of the system, in order to compare its outburst
   characteristics to those of ``normal'' dwarf novae. We invite those of
   you equipped with a CCD camera to obtain a couple of images of V446
   Her per night throughout the next four months, say, until the end of
   September.  To get a complete coverage (~5-10 measurements per day), it
   is crucial that we find collaborators in several continents. The
   resulting light curve will be published in a refereed journal, 
   including all contributors as co-authors."
