Classified as a symbiotic star by Rimoldini et al. (2023) based on a machine-learning technique applied to Gaia DR3 data, including astrometric, photometric, and photometric time series information. This star is located in the center of the globular cluster NGC 2808 and exhibits variability, as noted in Kunder et al. (2013). A periodicity of 375 days has been reported by Samus et al. (2020).
