Popis: An attempt was made to connect the number of spotless days in previous minimums of solar cycles with the main characteristics of the following cycles: height, total length, and length of the rise branch. According to the value of the sum of spotless days in the minimum of cycle 23 ΣDT0 = 800 (July 2010), the following characteristics of cycle 24 were obtained: the beginning is 2009.0 (January 2009), the length of the rise branch RW = 4.8 years, the date of the maximum is 2013.8 (October 2013), Wolf’s number in the maximum WM= 63, the length of the decline branch DW = 7.8 years, the total length DTmm = 12.6 years, and the end is 2021.6 (July 2021).
