Dear VSNETers,

Several BAA observers have noted a rapid fade of the nebular variable
AB Aur during the past 24 hrs - fading from 6.9 (Nov 30.8) to 8.1 
(Dec 01.8).   Has anyone else recorded similar activity? 
Our data is incomplete on this star, but a similar fade was recorded in
1975, when AB Aur reached below magnitude 8 within a day or so.  Apparently 
the fade was a short term event, lasting only a few days. 

regards,
Gary Poyner
