VSNET Weekly Campaign Summary

*** Last week news ***

(new targets)
  Nova Cen 2001		(RA = 13h55m41s.27, Dec = -64d15'57".9)

    W. Liller reported a possible nova of 8.6mag on October 1 
  (vsnet-campaign-nova 594, 595, 596, 602, 603, 604, 605).  
  A. Jones, A. Pearce, and M. Mattiazzo reported their confirmation 
  just after the discovery (vsnet-campaign-nova 597, 598, 600, 601).
    The object is now around 9.8mag (vsnet-campaign-nova 599, 606, 609).


  EF Peg		(RA = 21h15m04s, Dec = +14d03'50")

    As reported by E. Muyllaert in [vsnet-alert 6734], the SU UMa-type
  dwarf nova EF Peg started its new rare outburst of 11.1mag on 
  October 3.  EF Peg is a strange SU UMa-type star in the point 
  of its long cycle of superoutburst with a long orbital period of 
  near 2 hours, the edge of the "period gap" of CVs (vsnet-campaign 1180, 
  vsnet-campaign-dn 1674).  D. Starkey's data on October 6 detected 
  a probable superhump, which strongly indicates the current outburst is 
  a genuine superoutburst (vsnet-campaign-dn 1688).  The object is now 
  about 11.1mag and the outburst is still ongoing (vsnet-campaign-dn 1676, 
  1678, 1682, 1685).
  

  SN 2001ep		(RA = 04h57m00s.26, Dec = -04d45'40".2) 

    IAUC 7727 tells that the KAIT team discovered SN 2001ep on 
  October 3 (17.1mag) and 4 (16.8mag).  The recession velocity of 
  the host galaxy NGC 1699 is measured as 3900 km/s, from which 
  the expected maximum of typical SN Ia is mag about 15.3 
  (vsnet-campaign-sn 256).
 

  SN 2001eq		(RA = 23h04m56s.78, Dec = +19d33'04".8)

    IAUC 7728 tells that the KAIT reported SN 2001 first detected 
  on September 12 at 18.7mag.  The object was 17.2mag on October 4 
  (vsnet-campaign-sn 257). 
  

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

    The object rebrightened to 13.0mag on October 4 
  (vsnet-campaign-nova 607).


  SN 2001el		(RA = 03h44m30s.57, Dec = -44d38'23".7)

    The object is now bright at about 12.6mag (vsnet-campaign-sn 258).


  TY Psc		(RA = 01h25m36s.87, Dec = +32d23'05".3)
 
    The superoutburst was terminated around October 1 and 2 
  (vsnet-campaign-dn 1673).


  V4740 Sgr = Nova Sgr 2001 No. 3
			(RA = 18h11m45s.82, Dec = -30d30'49".9)

    The slow fading continues (vsnet-campaign-nova 608, 610).


  MV Lyr		(RA = 19h07m15s.93, Dec = +44d01'10".7)

    The object is now around 13mag (vsnet-campaign-nl 44).


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

    The late superhumps are still reported, and the international 
  campaign is ongoing (vsnet-campaign-dn 1672, 1675, 1677, 1683, 
  1684).   The humps were again growing on October 1 and 2 
  (vsnet-campaign-dn 1669, 1670).  On October 3, eclipses became
  prominent and then the amplitude of humps decreased 
  (vsnet-campaign-dn 1679).  The eclipse feature has been becoming 
  weaker as the system faded (vsnet-campaign-dn 1680).  The emergence 
  of humps (~0.4mag) is reported on October 7 (vsnet-campaign-dn 1686).
