How Do You Predict Sunspots? One knows the rate with which they will appear to produce the expected number of sunspots, but you can’t really predict when the next one will appear. Each sunspot cycle What are sunspots and what are they used to predict? Sound waves from deep inside the sun can allow astronomers
Is Solar Activity Increasing? Solar activity has been on a declining trend since the 1960s, as indicated by solar cycles 19-24, in which the maximum number of sunspots were 201, 111, 165, 159, 121 and 82, respectively. Is the Sun becoming more active? The sun’s new 11-year cycle of activity (Cycle 25) has just started,
What Is The 11 Year Sun Cycle? The Sun’s magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun’s magnetic field completely flips. This means that the Sun’s north and south poles switch places. Then it takes about another 11 years for the Sun’s north and south poles
How Long Sunspot Cycle? The duration of the sunspot cycle is, on average, around eleven years. However, the length of the cycle does vary. Between 1700 and the present, the sunspot cycle (from one solar min to the next solar min) has varied in length from as short as nine years to as long as
