We report the result of VLBI observation of the giant radio galaxy J1313+696(4C +69.15) at 2.3/8.4 GHz, only the core component of the giant radio galaxywas detected in the VLBI observation at the dual frequencies. The result showsa steep spectrum core with $\alpha=-0.82$ ($S \propto \nu^{\alpha}$) between2.3 GHz and 8.4 GHz. The steep spectrum core may be a sign of renewed activity.Considering also the upper limit flux density of 2.0 mJy at 0.6 GHz from Konaret al. 2004 the core has a GHz-peaked spectrum, implying that the core iscompact and absorbed. Further high resolution VLBI observations are needed toidentify if the steep spectrum core is consisting of a core and steep spectrumjet.
