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

(new targets)
  RX J0558.3+6753	(RA = 05h58m18s.0, Dec = +67o53'46")

    As reported on April 3 by T. Kinnunen, the ROSAT-selected CV 
  RX J0558.3+6753 experienced an outburst at 14.0mag.  
  This observations seems to confirm the dwarf nova nature 
  (vsnet-campaign 837).  A. Oksanen reported B=15.66, V=16.03, and 
  R=15.84 on April 5 (vsnet-campaign-dn 627).  The outburst seems 
  to be a normal one (vsnet-campaign-dn 620).


  TU Crt		(RA = 11h03m36s.50, Dec = -21d37'45".6)

    P. Nelson reported that the SU UMa-type dwarf nova TU Crt is 
  undergoing one of is relatively rare outbursts.  The brightness 
  (12.2mag) may suggest a superoutburst.  The last superoutburst 
  occurred in 1998 March, when the first-time superhumps were detected 
  (vsnet-campaign 840).  The superoutburst continues (vsnet-campaign-dn 631).


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

    The VSNET administrator team has received a request from FUSE 
  team to ask VSNET team to observe VV Pup (polar) on April 5 and 6, 
  in order to know the current activity state during the FUSE 
  observation.  This system has a 100 min orbital period and a large 
  hump when the pole is in view if it is in an active state 
  (vsnet-campaign 838).   The Kyoto team performed an observation 
  on April 5 (vsnet-campaign 839).


(continuous targets) 
  V485 Cen		(RA = 12h57m23s.30, Dec = -33d12'06".8)

    The superoutburst continues (vsnet-campaign-dn 619).


  Z Cha			(RA = 08h07m16s.29, Dec = -76d32'20".9)

    The fading from the superoutburst was reported 
  (vsnet-campaign-dn 622, 632).


  V1504 Cyg		(RA = 19h28m55.87s, Dec = +43d05'39".9)
    
    The superoutburst continues (vsnet-campaign-dn 626).


  Delta Sco		(RA = 16h00m19s.9, Dec = -22d37'17")

    Delta Sco is still bright at about 1.8mag (vsnet-campaign-be 96).


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

    The activity was still seen during the last week 
  (vsnet-campaign-blazar 173).


  V4643 Sgr		(RA = 17h54m40s.43, Dec = -26d14'15".7)

    The object is now in a gradually fading phase and the current 
  (April 4) magnitude is reported to be about 13.8 (vsnet-campaign-nova 278).

 
  V803 Cen		(RA = 13h23m44.5s, Dec = -41d44'30".1)

    The strong activity still continues (vsnet-campaign-dn 623).


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

    The outburst was faded (vsnet-campaign-dn 625).


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

    The activity around ~12.8mag is still continues 
  (vsnet-campaign-blazar 174).


  3C 279            (RA = 12h56m11s.1, Dec = -05d47'20")

    The current magnitude is about R=14.8 (vsnet-campaign-blazar 176).  
  M. Villata reported 3C 279 is sensibly rising on April 9 
  (vsnet-campaign-blazar 175).
