VSNET Weekly Campaign Summary

*** Last week news ***

(new targets)
  SN 2001gd		(RA = 13h13m23s.89, Dec = +36d38'17".7)

    Mr. Itagaki discovered SN 2001gd on Nov. 24.820. He reported 
  that it was mag 16.5.  The existence of the new object was confirmed
  immediately by Ms. R. Kushida on Nov. 24.851 (bright twilight), 
  and she reported it was mag 17.5.  The next day, she also observed 
  it and reported that it was mag 16.2 on Nov. 25.8.  A. Dimai 
  independently discovered it on Nov. 25.21 (mag 16.4).  The object is 
  about 52" west and 161" north (about 2'50" NNW) of the nucleus of the 
  large spiral (SA(s)c) galaxy NGC 5033. This galaxy has produced 
  SN 1985L, which was of type II-L and was mag 13.0 at maximum.  
  If SN 2001gd is of unreddened type Ia, its expected maximum is around 
  mag 12 (vsnet-campaign-sn 284).  Reported magnitude estimates of 
  this object shows no significant brightening betweeen November 24 - 28.  
  It seems not to be in a rapid-rising phase of SN Ia 
  (vsnet-campaign-sn 286).

 
(continuous targets) 
  GY Cnc		(RA = 09h09m50s.5, Dec = +18d49'47")

    The significant fading was reported on November 27.  The outburst 
  has already finished (vsnet-campaign-dn 1955).


  SN 2001gb		(RA = 09h59m00s.96, Dec = +17d49'12".4)

    This SN was revealed to be of type Ia near maximum light by 
  the CfA group (IAUC 7761; vsnet-campaign-sn 285).
 

  SN 2001gc		(RA = 05h55m26s.14, Dec = +51d54'34".2 )

    The CfA team revealed that this SN is of type Ia having larger
  expansion velocity than usual.  They commented that the expansion
  velocity (16600 km/s) suggests this SN to be well (~2 weeks) before
  maximum, but the inspection of their spectrum shows that it is 
  probably near maximum but has the larger expansion velocity.  
  Such a large expansion velocity is typical for the intrinsically 
  bright SN Ia (vsnet-campaign-sn 285).  


  WZ Sge		(RA = 20h07m36s.53, Dec = +17d42'15".3)

    The slow fading is still ongoing (vsnet-campaign-dn 1954).


  V1504 Cyg		(RA = 19h28m55.87s, Dec = +43d05'39".9)

    As reported by G. Poyner, a new outburst of this SU UMa-type 
  dwarf nova was detected on November 26 at 14.8mag.  It may be 
  a superoutburst (vsnet-campaign-dn 1953).
