Notes

Considered a candidate symbiotic star based on photometric appearance (Corradi et al., 2008), it is also listed as a confirmed symbiotic star in the ASAS-SN database (Jayasinghe et al., 2019). It has been detected in brightening by Gaia and the system was classified as an eclipsing CV with an orbital period of 0.145 days (Inight & Copperwheat, 2019).
