แสงออโรราหรือแสงเหนือ-แสงใต้ที่เกิดมากขึ้นในช่วงนี้เป็นผลโดยตรงของปรากฏการณ์ Solar Maximum
The sun releases different amounts of energy at different times. A cycle comes with a period of approximately 11-12 years, called the "Solar Cycle". It’s cycle related to changes in the sun's magnetic field. As a result, each period of the sun releases different energy.
When the sun releases the most energy, called "Solar Maximum", there will be the most sunspots on the photosher. And on the contrary, the period when the sun releases less energy (quiet) and there is almost no sunspot on the surface is called "Solar Minimum".
