[vsnet-outburst 2036] Re: V550 Cyg no outburst

[Gary Poyner <gp@star.sr.bham.ac.uk>]

Thanks to Finnish observers for checking this.  As I stated
in my VS report (but not shown below) I was very unsure of
the I.D of V550 Cyg.  The TA chart which I use does not
show faint star detail, and the Downes & Shara image is
impossible to use.

If an image of the field were to be made available, I would
be most grateful for a copy.

Best regards,
Gary
