Päikesemaksimumiks

Päikesemaksimumiks refers to the period of highest solar activity within the sun's approximately 11-year cycle. During this phase, the Sun exhibits an increased number of sunspots, solar flares, and coronal mass ejections. These phenomena are driven by the shifting and strengthening of the Sun's magnetic field.

The increased solar activity can have observable effects on Earth. More frequent and intense solar flares can disrupt radio communications, satellite operations, and power grids. Geomagnetic storms, caused by coronal mass ejections, can lead to spectacular auroral displays visible at lower latitudes than usual. Spacecraft and astronauts in orbit are also at higher risk of radiation exposure during solar maximum.

Scientists monitor solar activity closely to predict and prepare for the impacts of solar maximum. This monitoring involves observing sunspots, measuring solar magnetic fields, and tracking the frequency of solar flares and coronal mass ejections. Understanding the solar cycle and its maximum is crucial for various fields, from space weather forecasting to astrophysics. The current solar cycle, Solar Cycle 25, is predicted to reach its maximum around July 2025.
