Discovery of a new variable star TYC 4246-883-1 in Cepheus constellation is reported. The star has mean brightness of about 11 mag in Johnson V. It appears to be a delta Scuti type pulsator with a dominant frequency of f=19.6174 c/d and amplitude changingfrom0.025to0.065 mag. The strong amplitude variation suggests the existence of multiple pulsation modes, which we have not detected directly yet.
