VSNET Weekly Campaign Summary

*** Last week news ***

(new targets)
  CI Cam		(RA = 04h19m42s.08, Dec = +55d59'57".8)

    The B[e]-X ray transient CI Cam is reported to be brighter 
  than usual.  M. Simonsen reported that it was 11.4mag on February 
  18, somewhat brighter than its quiescent of 11.9-12.0mag 
  (vsnet-campaign-xray 114, vsnet-campaign-be 165).  Since then, 
  the slightly bright state (or possibly gradual brightening) 
  continues (vsnet-campaign-xray 115, 116, vsnet-campaign-be 166, 
  167, 168, 169).  

  SDSSp J173008.38+624754.7 (RA = 17h30m08s.38, Dec = +62d47'54".7)

    As reported by M. Simonsen on February 18, the SU UMa-type dwarf 
  nova SDSSp J173008.38+624754.7 experienced a bright (13.6mag) 
  outburst (vsnet-campaign-dn 2131).  The Kyoto team performed 
  time-series photometry on February 20 (vsnet-campaign-dn 2138), 
  and detected superhumps with amplitude of 0.3mag 
  (vsnet-campaign-dn 2140).  The current outburst is thus a 
  superoutburst, and its supercycle is around 100 d, which is one 
  of the shortest supercycles in usual SU UMa-type dwarf novae 
  (vsnet-campaign-dn 2131).  The superoutburst is still ongoing 
  (vsnet-campaign-dn 2134).

  lamda Pav		(RA = 18h52m12s.95, Dec = -62d11'14".4)

    S. Otero and C. Scalia reported that lamda Pav (4.00-4.26mag 
  in GCVS) is bright at 3.98 mag on February 24 (vsnet-campaign-be 
  171, 172).

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

    As reported by M. Reszelski, a new ER UMa-type star, IX Dra 
  experienced a bright (14.7mag) outburst on February 19.  The 
  brightness indicates a superoutburst (vsnet-campaign-dn 2135).

  AX Per		(RA = 01h36m22s.72, Dec = +54d15'02".7)

    This object is now in eclipse (vsnet-campaign-symbio 7).

  GH Gem		(RA = 07h04m05s.49, Dec = +12d02'29".1)

    The object was reported to be faint at 13.7-13.8 on February 
  19-20 (vsnet-campaign-symbio 9).

  SN 2002aw		(RA = 16h37m29s.06, Dec = +40d52'50".3)

    This supernova turned out to be a type Ia near maximum on 
  February 18.52 according to IAUC 7834 (vsnet-campaign-sn 356).

  HadV98		(RA = 17h23m14s.5, Dec = -22d52'05")

    K. Haseda reported that RCB? pec? star HadV98 became faint 
  (12.2-12.3p mag) again since January 25 (vsnet-campaign-unknown 65).

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

    A fading of this VY Scl-type star was reported by M. Simonsen 
  on February 18 (13.9mag) and confirmed by E. Muyllaert on 
  February 24 (13.9mag) (vsnet-campaign-nl 72).

(continuous targets) 
  GK Per		(RA = 03h31m12s.50, Dec = +43d54'17".8)

    The slightly bright state continued (vsnet-campaign-gkper 11, 
  12, 13, 14, 15, 16, 17, 18).

  chi Cyg		(RA = 19h50m33s.9, Dec = +32d54'50")

    The object is now bright at 4.1-4.2mag (vsnet-campaign-mira 9, 
  10, 11, 12, 13).

  SN 2002ao		(RA = 14h29m35s.74, Dec = -00d00'55".8)

    The object was reported to be 16th mag (vsnet-campaign-sn 355).

  HT Cas		(RA = 01h10m12s.98, Dec = +60d04'35".9)

    The object has remained at the relatively bright state 
  (16.0mag) compared with its quiescent magnitude over one week 
  (vsnet-campaign-htcas 25).

  RR Tau		(RA = 05h39m30s.53, Dec = +26d22'26".3)

    The brightening continues.  11.4mag was reported on February 23  
  (vsnet-campaign-orion 18).

  SN 2002ap		(RA = 01h36m23s.85, Dec = +15d45'13".0)

    The gradual fading continues.  It is now 13th mag 
  (vsnet-campaign-sn2002ap 155, 159, 162, 164, 165, 166, 167, 168, 
  169, 170, 173, 174, 175, 176, 177, 178, 179, 180).  Between 
  January 21 and January 29, 2002, no burst which could be localized 
  by the IPN was found to have a source position in any way 
  consistent with that of the supernova (vsnet-campaign-sn2002ap 161). 

  V2540 Oph		(RA = 17h37m34s.36  Dec = -16d23'18".4)

    The object again brightened to 9.6mag as reported by E. Muyllaert 
  on February 21.  This indicates that this nova is a highly 
  oscillating one (vsnet-campaign-nova 846, 847).

  SN 2002an		(RA = 08h22m47s.76, Dec = +24d17'41".7)

    The object is now gradually fading (vsnet-campaign-sn 354).

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

    The gradual fading almost stopped around February 22-23 
  (vsnet-campaign-v838mon 197, 198, 199, 200, 201, 202, 203, 204, 
  205, 206, 207, 208, 209, 210, 211, 213, 214, 215, 216, 217, 218, 
  219, 220).  C. Sherrod reported a slow brightening at around 
  8.4mag on February 24 (vsnet-campaign-v838mon 221, 222, 223). 

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

    The object is still very faint (vsnet-campaign-dn 2137, 2142).

  U Gem                 (RA = 07h55m05s.55, Dec = +22d00'09".2)

    It was fading from the maximum of the last outburst 
  (vsnet-campaign-ugem 17, 18, 19, 20).

  UX Ori		(RA = 05h04m30s.39, Dec = -03d47'18".3)

    The object is still faint (vsnet-campaign-orion 17).  The 
  duration of faint state is relatively long (vsnet-campaign-orion 19).

  DW Cnc		(RA = 07h58m56s.80, Dec = +16d16'48".2)

    Reported observations show very strong activity of DW Cnc 
  (vsnet-campaign-nl 65, vsnet-campaign-dn 2136).

  V1039 Cen		(RA = 13h55m41s.27, De = -64d15'57".9)

    A. Retter reported that observations by M. Bos show ~1.7-h 
  modulations with a full amplitude of ~0.05 mag. He also proposed 
  three interpretations of the modulations; orbital period, 
  superhump period, or spin period (vsnet-campaign-nova 845).  The 
  object has recently been at about 13.0mag (vsnet-campaign-nova 844).

  V1413 Aql             (RA = 19h03m46s.84, Dec = +16d26'17".1)

    The next eclipse will occur soon (vsnet-campaign-symbio 8).

  TV Col		(RA = 05h29m25s.5, Dec = -32d49'05".2)

    A fading of this object was reported (vsnet-campaign-ip 85, 
  vsnet-campaign-nl 66), but it turned out to be an error observation 
  (vsnet-campaign-nl 67, vsnet-campaign-ip 86).

  CR Boo		(RA = 13h48m55s.42, Dec = +07d57'30".3)
    The outburst since February 18 is still ongoing.  The object 
  is at about 14mag (vsnet-campaign-dn 2139, 2141).
