Rho was first described as a variable star in 1901 when until 1946 it varied in brightness between 4.1 to 4.5 then unexpectedly in that year it faded to magnitude 6.0 it then returned to about magnitude 4.5. The same thing happened in 2000 and 2001. Checking back even further the same thing was recorded in 1893. There appears to be a cycle of events every 50 or so years. So what is going on here?
