HR 8752 is one of the brightest stars of the Galaxy. Humphreys (1978) gives its absolute visual and bolometric magnitudes between −9.1 and −9.5, and between −9.2 and −9.5, respectively. The star received its variable star name, V509 Cas, in 1972 (Kukarkin et al., 1972). Radial velocity variations were first noticed by Harper (1923) and by Campbell and Moore (1928). In Harvard Ann. Vol. 44 (Pickering, 1899) there are indications for light variation at the end of the 19th century.
