Activity of the Lyrid meteor shower in the years 1945–1952

The activity of the Lyrid meteor shower in the years 1945–1947 and 1952 is studied. For this purpose more than 470 visual records of Lyrid meteors, observed at the Skalnaté Pleso Observatory over a period of four years, are analysed and converted to zenithal hourly rates. The correction factor cosyZR with the exponent γ = 1.47 is used.
