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

(new targets)
  SN 2000ek		(RA = 02h10m30s.04, Dec = -53d49'28".0)

    This new supernova appeared in the host galaxy ESO 153-G27.  
  The magnitude on November 7 and 8 is 17.0.
  The location is about 22" west and 44" north of the center of the host.  
  H. Yamaoka reported the expected maximum of typical SN Ia is mag about 16
  (vsnet-campaign-sn 107).

 
(continuous targets)
  SN 2000dx		(RA = 02h18m26s.88, Dec = +05d39'02".0)

    H. Yamaoka forwarded the observation report by M. Frederick which 
  shows the magnitude of 15.26 on November 8.  This value is nearly 2 mag 
  brighter than the expected in [vsnet-alert 5357] and [vsnet-campaign-sn 105]
  (vsnet-campaign-sn 107).
   
  
  V1028 Cyg		(RA = 20h00m52.13s, Dec = +56d56'22.3")

    Kyoto team reported on November 9 that V1028 Cyg had faded to R=15.5. This 
  indicates a decline rate of November 6-9 is about 0.4mag/d and the duration 
  is rather shorter than typical superoutbursts (vsnet-campaign-dn 240).


  Delta Vel		(RA = 08h44m42s.1, Dec = -54d42'30")

    B. Fraser reported observations corrected using appropriate magnitudes 
  of comparison stars and show no significant variability out of eclipse on 
  November 4, 5, and 6 (vsnet-campaign-deltavel 19).  S. Otero showed a 
  new eclipse ephemeris with a period of 45.15100 days (see also 
  [vsnet-campaign-deltavel 23].  He commented that observations on November 
  12/13 are important to rule out another period of 27.10 day definitively 
  (vsnet-campaign-deltavel 22).  On November 12, S. Otero reported no eclipse 
  was observed at that time and the 45.150 day period is now almost real
  (vsnet-campaign-deltavel 24).

 
  BL Lac		(RA = 22h02m42.86s, Dec = +42d16'37.6")

    The object is slightly fainter as reported by D. Rodriguez, V=14.35 on 
  November 9 (vsnet-campaign-blazar 90).


  PKS 2005-489              (RA = 20h05m47.4s, -48d58'45".0)

    The object is still active (vsnet-campaign-blazar 91).


*** General information ***

  Delta Vel
    S. Otero presents a good pair of comparison stars in 
					[vsnet-campaign-deltavel 20]
	and see also [vsnet-campaign-deltavel 21]
