   For readers' potential interest, the outburst already started in 2006
(see also that CBET issue).  The initial announcement of brightening
was reported by Berto Monard (vsnet-alert 8913, 2006 April).

   His subsequent observations in 2006 were as follows:

  YYYYMMDD(UT)   mag  observer
  20060402.060  12.00V  (Berto Monard)
  20060430.119  11.97V  (Berto Monard)
  20060622.110  12.08V  (Berto Monard)
  20060719.860  12.24V  (Berto Monard)
  20060827.850  12.42V  (Berto Monard)
  20060924.800  12.55V  (Berto Monard)
  20061122.740  12.96V  (Berto Monard)

   So, it would be fairer to refer to this detection in describing
the current state of activity.
