A prefix to a coordinate name is enclosed in parentheses. The presence/absence of a β€œJ” indicates that the epoch of the coordinates is J2000/B1950.
Year of initial X-ray outburst/total number of X-ray outbursts.
Period and f(M) corrections by AM Levine and D Lin, private communication.
Colon denotes uncertain value or range.
Additional outbursts in optical archives: A 0620 (1917) and V404 Cyg (1938, 1956).
Casares et al. 2004; possible alias period of 61.5 hr.

Period confirmed by A.M. Levine and D. Lin, private communication.
β€œQ” denotes quasi-persistent intervals (e.g., decades), rather than typical outburst.
