Initially identified as a symbiotic candidate and chosen for an AAVSO observing campaign (AAVSO Alert 681) by Adrian B. Lucy from Columbia University. Subsequently confirmed as a symbiotic star by Lucy (2021), whose observations revealed the presence of an M6 III star and emission lines of H I, as well as flickering and X-ray emission.
