(2007) who noted that the near IR (K,J-K) CM diagram has a predominantly red HB. This "candidate" globular cluster was discovered by by Hurt et al. (2000) in the Two Micron All-Sky Survey (2MASS) data set and confirmed by Ivanov et al. (2000) from an near IR (K,J-K) CM diagram. ================================================================= Discovery of the variable stars in 2MASS-GC02 V1-5 Borissova et al. (2007) with RA, dec and a K-band ID chart ----------------------------------------------------------------- Alonso-Garcia et al. (2013) found 5 more RR Lyrae candidates in the VVV survey. They derived a mean period

~0.61 days. They were not able to confirm any of the candidates found by Borissova et al. (2007). ================================================================= References Alonso-Garcia, J., Dekany, I., Catelan, M., Contreras Ramos, R., Minniti, D. 2013, arXiv:1307.0419v1 Borissova, J., Ivanov, V.
