The historical light curve of the semiregular pulsating star RT Vir (SRb, Sp M8III) with a maser emission is analyzed based on the AAVSO database. The star is extensively studied in the IR, radio and the optical ranges. The value of the period from the CCVS (155d) conflicts with some observational data. Signs of a systematic variability were also …
