Notes

First mentioned in Hoffleit (1975) and included as a symbiotic candidate in Vaidis (1988). The star studied by Hoffleit (1975), however, corresponds to OY Cyg according to Kazarovets & Samus (1998). In Heinze et al. (2018), this object is classified as a close binary with a period of around 0.36 days, which is well consistent with the ZTF data.
