[vsnet-obs 4137] (repost) chart of DO Dra



   For observers' convenience, I here repost the latest VSNET chart of
DO Dra (1995 Oct. 24).   Magnitudes inparentheses are from Henden and
Honeycutt (1995).

   As notified by several observer, the brighter end of the older AAVSO
chart is systematically brighter, which is probably the cause of some
discrepancies between observers.
