We present new CCD VI photometry of the distant globular cluster Pal 13 . Fourier decomposition of the light curves of the three cluster member RRab stars lead to estimations of [ Fe/H ] =-1.65 , and a distance of 23.67 \pm 0.57 kpc . Light and colour near minimum phases for RRab stars leads to an estimate of E ( B - V ) =0.104 \pm 0.001 . A V / ( V - I ) colour-magnitude diagram , built exclusively with likely star members , shows consistency with the above parameters and an age of 12 Gyrs . A search of variable stars in the field of view of our images revealed the variability of a red giant cluster member and of three probably non-member stars ; two RRab stars and one W Virginis star or CW . The GAIA proper motions of member stars in Pal 13 show a significant scatter , consistent with the scenario of the cluster being tidally stripped .
