Parameteres of solar cycles are found usind revisited sunspot numbers in 2015. Correlations between cycle parameters were studied. Solar cycle 25 was predicted using regression equations obtained. I was predicted that minimum and maximum of the cycle (8.3 and 166.7) will occur in May of 2020 and November 2024 to February 2025 respectively.
