We report the discovery of a variable star displaying significant variability, characterized by periods of quiescence interspersed with episodic flaring activity. The object has increased in brightness by approximately 1.8 magnitudes compared to its last recorded observation on March 30, 2025. Period analysis of ZTF light curves performed with Peranso suggests a periodicity of roughly 323 days. 2026TNSTR1648....1K N
