Note: The observation of AB Aurigae was made following G. Poyner's
  alert of a rapid fade of this star [vsnet-obs 8789]. It was stated
  that BAA observers recorded a fade from mv = 6.9 to 8.1 during
  1997 Nov. 30.8 UT to Dec. 1.8 UT. T. Kato has compiled a list of
  nearby comparison stars using Hipparcos and Tycho data [vsnet 1057].
