The ZAND type star V2756 Sgr appears to have declined as indicated by the
following single morning observation. Also listed are observations from
the end of last year (2000 October) prior to conjunction with the sun.
This star is plotted on chart 614 of the VSS RASNZ which includes a V
sequence. V2756 Sgr typically shows little variation around visual
magnitude 13.0 or 13.1 and this is appears to be the first major fade since
I commenced regular observation in September 1988 (unless it always fades
when in the morning sky as I lack regular morning observations!).
