New variables in M5 (NGC 5904) and some identification corrections

Understand

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.
