We report an X-ray flare from 3XMM J014528.9+610729 , serendipitously detected during the observation of the open star cluster NGC 663 .
The colour-colour space technique using optical and infrared data reveals the X-ray source as a candidate spiral galaxy .
The flare shows fast rise and exponential decay shape with a ratio of the peak and the quiescent count rates of \sim 60 and duration of \sim 5.4 ks .
The spectrum during the flaring state is well fitted with a combination of thermal ( Apec ) model with a plasma temperature of 1.3 \pm 0.1 keV and non-thermal ( Power-law ) model with power-law index of 1.9 \pm 0.2 .
However , no firm conclusion can be made for the spectrum during the quiescent state .
The temporal behavior , plasma temperature and spectral evolution during flare suggest that the flare from 3XMM J014528.9+610729 can not be associated with tidal disruption events .
