ADC_Keywords: Clusters, globular ; Stars, variable ; Photometry Keywords: globular clusters: individual: M5 (NGC 5904) - stars: variables: RR Lyrae Abstract: We report twelve variables not previously detected in the globular cluster M5 (NGC 5904); one SX Phe and eleven semi-regular variables (SR). Their identifications, equatorial coordinates, ephemerides, and light curves are given. Furthermore, we have explored the light curves of a group of stars whose variability has not been confirmed and that are marked as probable non-variables in the CVSGC. Finally, we offer detailed identifications for some of the known variables in crowded regions that were misidentified in previous studies. We shall also address the cases of the cataclysmic variable or U Gem type V101 and of the variable blue straggler V159. Description: VI time-series photometry of stars with no confirmed variability, stars with corrected classifications and identification and of newly discovered variables (V170-V181) in M5 (NGC 5904).
