VSNET Weekly Campaign Summary

*** Last week news ***

(new targets)
  SN 2002cj		(RA = 15h21m20s.71, Dec = -19d51'27".3)

    The LOTOSS team discovered SN 2002cj on images taken on April 21 
  (mag about 16.0) and 22 (mag about 15.9).    ESO 582-G005, the host 
  galaxy of SN 2002cj, is a moderate-distant galaxy.  The expected 
  maximum for typical SN Ia is mag about 16.8.  The reported magnitude 
  is somewhat brighter than the expected one (vsnet-campaign-sn 416).

  
(continuous targets) 
  V4741 Sgr = Nova Sgr 2002		
			(RA = 17h59m59s.38, Dec = -30d53'21".9)

    This nova has been given the permanent designation V4741 Sgr 
  (IAUC 7882; vsnet-campaign-nova 928).  T. Kato reported the 
  object was reported to be fading rapidly (t2 ~ 9d) 
  (vsnet-campaign-nova 929).  


  RX J1643.7+3402       (RA = 16h43m45s.1, Dec = +34d02'35")

    T. Vanmunster performed time-series observations and reported 
  0.2-0.3mag modulations with irregular periods of 10-15 min.  
  He also reported that there's a superimposed, much longer term 
  modulation, likely related (or identical) to the photometric 
  modulation originally reported by Michaelian (vsnet-campaign 1304,
  1305).


  DV UMa		(RA = 09h46m36s.67, Dec = +44d46'45".1)

    A. Oksanen reported that the object was 15.50mag on April 22 
  and the light curve was rather flatter (vsnet-campaign-dn 2333).


  MKN 421		(RA = 11h04m27s, Dec = +38d12'32")

    The fading continues.  It was reported to be 12.9-13.2mag 
  during the last week (vsnet-campaign-blazar 259).


  DY Per		(RA = 02h35m17s.12, Dec = +56d08'44".7)

    A. Alksnis reports that the object is further fading.  
  The fading rate is 0.04mag/d in red light and 0.025mag/d in 
  blue.  The object was reported to be 11.0mag (red) and 14.6mag 
  (blue) on April 22 (vsnet-campaign-rcb 25).  The slow fading 
  still continues (vsnet-campaign-rcb 26).
   

  V803 Cen		(RA = 13h23m44s.5, Dec = -41d44'30".1)

    The sudden fading was reported on April 18 and confirmed at 
  16.3mag on April 20 (vsnet-campaign-dn 2334).


  V893 Sco		(RA = 16h14m45s.26, Dec = -28d39'30".3)

    The object was reported to be brightening on April 23 
  (vsnet-campaign-dn 2336).


  V2051 Oph		(RA = 17h08m19.1s, Dec = -25d48m31.1s)

    The object faded from the superoutburst as reported by
  R. Stubbings on April 25 (vsnet-campaign-v2051oph 3, 4).


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

    A bright outburst (14.7mag) was detected by M. Reszelski 
  on April 22 (vsnet-campaign-dn 2335).


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

    A. Oksanen reported that the object was still calm at 17.5mag
  on April 21 (vsnet-campaign-dn 2332).


  V838 Mon		(RA = 07h04m04s.816, Dec = -03d50'50".94)

    When the object was about 10.3-10.5mag, the gradual fading was 
  interrupted by a sudden, dramatic fading to 12.4mag on April 27 
  (vsnet-campaign-v838mon 345, 347).  The rapid fading was confirmed 
  on April 27 and 28, and it is still in fading 
  (vsnet-campaign-v838mon 348).
