V657 Cas = NSV14731: large-amplitude variation and revised position by Toa
Akira Takao (Kita-kyushu, Japan) reports the discovery of large-amplitude
variation in V657 Cas.
V657 Cas = NSV 14731

This observation supports that the star is a large-amplitude Mira star.
Takao also provides the following revised position of this star:
235204.9 +614813 (J2000.0)
