VSNET Weekly Campaign Summary

*** Last week news ***

(continuous targets)
  CT Hya		(RA = 08h51m04s.50, Dec = +03d07'43".5)

    Superhumps were clearly detected on November 16 and 17
  (vsnet-campaign-dn 3040).  The superoutburst continued on November
  22 (vsnet-campaign-dn 3041, 3044).  The November 23 data clearly
  show a ~0.8 mag drop, indicating that the superoutburst has entered
  the rapid decline stage (vsnet-campaign-dn 3048).


  SN 2002hy		(RA = 10h54m39s.18, Dec = -21d03'41".2)

    According to IAUC 8019, the ESO team has revealed that it is a
  peculiar type-Ib supernova soon after explosion.  He I lines are
  prominent, and they have P-Cyg profiles (v_exp about 9500 km/s
  derived from He I 587.5 nm absorption minimum).  Narrow H-alpha and
  H-beta absorption lines are identified at v_exp about 16000 km/s,
  which are probably made by the outermost thin hydrogen-rich layer.
  It is considerably reddened (E(B-V) about 0.17), so its luminosity
  is somewhat larger than normal SN Ib (vsnet-campaign-sn 508).


  RX And		(RA = 01h04m35s.55, Dec = +41d17'58".0)

    A new outburst was detected on November 19 by E. Muyllaert.  A
  possible low state had finished, but the outburst interval is rather
  unusual (vsnet-campaign-dn 3042).


  SW UMa		(RA = 08h36m42s.80, Dec = +53d28'38".2)

    On Nov. 16, SW UMa seems to have become slightly brighter than on
  the previous nights, breaking the slow declining trend.  Short-term
  variations with time-scales of 10-20 min were strongly present.
  Some of them seem to show some degree of coherence.  Some of the
  variations look like to be associated with late superhumps and their
  harmonics (vsnet-campaign-dn 3039).  The object kept its
  post-superoutburst magnitude level on November 19.  A new humps
  having a superhump-like profile appeared, although the period is
  different from ordinary superhumps or late superhumps
  (vsnet-campaign-dn 3043).


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

    A new outburst of 14.1mag was reported on November 22 by
  E. Muyllaert (vsnet-campaign-dn 3045).


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

    The object further faded (vsnet-campaign-rcb 86).


*** Future schedule ***

  MINE OBSERVATIONS OF CYG X-1
  F. Mirabel announced that the INTEGRAL satellite will point to
  Cygnus X-1 for 1 million seconds between November 24 and December
  6. In the context of the "MINE" collaboration
  (http://elbereth.obspm.fr/~fuchs/mine.html), monitoring programs are
  recommended for this period.

  Corrigendum:
    In the last "VSNET Weekly Campaign Summary"...
    >  SN 2002hc		(RA = 08h17m06s.05, Dec = -27d27'27".0)
    >
    >    H. Yamaoka reported a revised estimation of magnitude on September
    >  9 to be 15.4CR mag based on GSC2.2 Fmag and UCAC1 magnitude.  He
    The date is not "September 9", but "November 4.927".  
    Sorry for confusion.
