RZ Vul is catalogued as type RVB with a range of 11.7-15.0V, however it's identity has been somewhat confused over the years. It was first noted by Wolf & Von in 1906 after which it was ignored for 60 years. In 1966 it was classified as type UG/NL, 1977 RVB and in 1986 RCB
It's clear from the above light curve that the minimum has been deepening since 2000, with the minimum of September/October 2014 being historically the faintest yet recorded in this star.
