[vsnet-campaign 1333] VSNET Weekly Campaign Summary




VSNET Weekly Campaign Summary

*** Last week news ***

(new targets)
  V982 Oph		(RA = 17h52m37s.86, Dec = +07d32'52".4)

    According to IBVS 5302, V982 Oph is shown to be a dwarf nova
  (Antipin and Samus).  Please monitor this object, and make
  time-series photometry when a new outburst is detected
  (vsnet-campaign-dn 2741).


  New radio-selected CV in Sextans

    H. Bond reported: During the FIRST ("Faint Images of the Radio Sky
  at Twenty Centimeters") 1.4 GHz radio survey, using the Very Large
  Array, the radio source FIRST J102347.6+003841 has been identified
  with a previously unknown 17th-mag Galactic cataclysmic variable
  (CV).  Spectroscopic observations suggest that the CV is a DQ Her-
  or AM Her-type magnetic CV, as are the handful of other CVs that are
  known to be radio sources.  CCD photometry obtained at Kitt Peak
  shows rapid flickering and slower variations with a peak-to-peak
  amplitude of at least 1 mag, but has not as yet revealed the orbital
  period (vsnet-campaign-polar 8).
 

  WR104			(RA = 18h02m04s.0, Dec = -23d37'41")

    The object is gradually brightening.  K. Haseda reported 12.3p and
  12.2p mag on August 9 and 13, respectively (vsnet-campaign-wr 2).


  SN 2002eo		(RA = 01h52m55s.18, Dec = +36d03'22".2)

    The LOTOSS team discovered SN 2002eo on images taken on August 20
   when it was 18.0mag.  NGC 710, the host galaxy of SN 2002eo, is a
   disturbed spiral galaxy.  The expected maximum for typical SN Ia is
   mag about 16.5 (vsnet-campaign-sn 465).


  V425 Cas		(RA = 23h03m38s.60, Dec = +53d17'10".8 )

    Observations by T. Kinnunen show variations between 15.6:-14.6 mag
  in this ~20 days (vsnet-campaign-nl 96).


(continuous targets)
  TK5                   (RA = 19h17m26s.5, Dec = +37d10'41")

    The object experienced an outburst (14.7mag on August 19 by
  T. Kinnunen) (vsnet-campaign-dn 2743).


  WR106                 (RA = 18h04m43s.5, Dec = -21d09'29")

    K. Haseda reported a minor fading (<12.6p mag) on August 5
  (vsnet-campaign-wr 3).


  BX Mon		(RA = 07h25m22s.7, Dec = -03d35'50")

    A brightening to 9th mag was reported.  The present level of
  brightness was last recorded in 1999 (vsnet-campaign-symbio 25, 26).


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

    The object has faded from the superoutburst (vsnet-campaign-dn 2728).  


  Z UMi                 (RA = 15h02m01s.35, Dec = +83d03'48".7)

    No large variation has been reported (vsnet-campaign-rcb 65).


  BF Ara		(RA = 17h38m10s.40, Dec = -47d10'43".4)

    The superoutburst is still ongoing (vsnet-campaign-dn 2735, 2745,
  2748).  T. Kato reported that combined light curves obtained by
  G. Bolt and P. Nelson yielded a superhump period of 0.0881 d, which
  is slightly longer than the single-night determination.  It may be
  possible that BF Ara experienced a stage of rapid period evolution
  (vsnet-campaign-dn 2736, 2738).  With a new data set on August 21 by
  G. Bolt, T. Kato reported a revised superhump period of 0.08805(2)
  d.  The mean fading rate during the present superoutburst plateau is
  0.08 mag/d, which is relatively small among SU UMa-type dward novae
  (vsnet-campaign-dn 2739).  The profile of superhumps on August 23
  has become more symmetric than before (vsnet-campaign-dn 2747).


  AH Her		(RA = 16h44m09s.99, Dec = +25d15'02".1)

    The object entered a standstill at about 12.5mag
  (vsnet-campaign-dn 2731, 2744, 2750). 


  ES Aql		(RA = 19h32m21s.58, Dec = -00d11'31".2)

    The slow fading continues (vsnet-campaign-rcb 61).


  DH Aql		(RA = 19h26m12s.05, Dec = -10d15'21".4)

    The object has faded, and no rebrightening was observed
  (vsnet-campaign-dn 2737). 


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

    D. West reported that the spectrum on 08/15/02 shows the H alpha
  emission feature (vsnet-campaign-be 199).

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

    A bright outburst to 12.5mag was detected by R. Stubbings on
  August 21 (vsnet-campaign-dn 2742).  The object was still bright on
  August 24 and 25 (vsnet-campaign-dnn 2746, 2749).


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

    The object is now gradually brightening (vsnet-campaign-rcb 64).


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

    The bright state is reported to continue since August 12.  It may
  be a superoutburst (vsnet-campaign-dn 2740).


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

    The faint state continues (vsnet-campaign-nl 95).


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

    S. Kiyota reported 10.66C mag on August 20 (vsnet-campaign-v838mon 374). 


  V348 Sgr		(RA = 18h40m19s.94, Dec = -22d54'29".1)

    The bright state continues (vsnet-campaign-rcb 63).


  omicron Cet           (RA = 02h19m20s.67, Dec = -02d58'27".1)

    The object is now around maximum (vsnet-campaign-mira 31).
