[vsnet-chat 482] BL Lac sequence preview

[bas@lowell.Lowell.Edu (Brian Skiff)]

     I am nearly finished collecting published photometry for stars in the
field of BL Lac.  There are a number of loose ends to tie off, which will
have to wait until tomorrow.  However, it is clear that there are no large
differences among the half-dozen sources, at least for the visual observers.
The recently posted AAVSO chart shows a sequence from the AFOEV, which is
in turn clearly based on Bertaud's photoelctric observations for the same
stars.  These numbers are in the right ballpark.
     I will post the complete BVRI summary with positions in about 12-14
hours.....
