The ZAND star V2756 Sgr appears to be in eclipse as indicated by the
following single morning sky observation. This star has a usual visual
magnitude near 12.6 to 13.0. My past observations are scattered in time
but the previous eclipse observed in 2001 March has an interval of some 741
days or about 3x247 day cycles. Prior to that an event was observed in
1998 May, 1740 days or 7x247 days. This is slightly longer than the
currently accepted 243 days. Further observations would help confirm if
this longer period is indeed correct.
