This paper reports the serendipitously discovery of a new variable star with mean visual magnitude +14.73 +/- 0.03 mag and mean V-R color indice 0.33 +/- 0.03 in Ophiuchus constellation (RA = 16h 53m 02.14s, DE = -01°09' 5,6" (J2000.0)). The shape of the raw lightcurve and the observed periods lead to the conclusion that the star is a delta Scuti with a period of 0.05300 +/- 0.00004 days with an amplitude of 0.07 +/- 0.01 mag in R band. The knowledge of the star period allows an estimate of the distance that, considering interstellar absorption, is about 1000 pc.
