| It is also believed that an increase in sunspot activity can have an affect on pole reversal. |
| He says sunspots are an indicator of the amount of energy radiating from the sun and we're currently coming out of a sunspot minimum. |
| Scientists have noticed that sunspot activity tends to follow a regular cycle that peaks every 11 years. |
| Until now, Dr. Wolff said, there have been only indirect and inconclusive evidence for Rossby waves through sunspot observations. |
| Many magnetic storms occurred in tandem with reports of solar flares or of large sunspot regions near the Sun's equator. |
| Three methods to determine the heliographic latitude and longitude of sunspot groups are described below. |
