Notes

Discovered as an X-ray source in the NGC2403 field by Schlegel & Pannuti (2003). Binder et al. (2015) noticed properties similar to an NS accreting from the wind of a late-type giant (e.g., symbiotic star GX 1+4). Rapid X-ray variability was observed. Merc et al. (2020) analyzed multifrequency observations of the object, together with the photometric variability and concluded that the star is an active foreground K-type dwarf. Spectroscopic observations of Dubovský et al. (2021) confirmed the classification.
