Notes

Initially suspected due to its X-ray emission, it was proposed that the optical counterpart might be a K-type giant (Tomsick et al., 2012). The study by Fortin et al. (2018) suggested the presence of a KV secondary and estimated a distance of 45 to 85 pc, indicating a low-luminosity CV. A period of 31.5 days was identified using Gaia spectroscopic data (Beck et al., 2023).
