The Earth’s magnetic field has a crack and solar flares could get through

The trapped energies in a sunspot can be released in an intense eruption which is called a solar flare. When the eruption consists of only radiation, it is called a solar flare. It can also consist of charged particles from the solar surface which is referred to as a coronal mass ejection (CME). When this travels outwardly from the Sun, it is referred to as solar winds and becomes responsible for space weather.

Buzzing sunspot AR3165

For centuries, scientists have been looking at the sun to predict space weather and the sunspots are a major marker of the intensity of activity. As the Sun approaches the peak of its 11-year solar cycle, the number of sunspots have been observed to increase in number as well as activity.

The next solar cycle peak is expected in 2025 and activity has been picking up in the past few months. Last week, the sunspot AR3165 sent out eight solar flares, each belonging to Class M, a medium-intensity categorization of solar flares. Any increased intensity could have resulted in the flares being classified as Class X flares, the highest intensity known to man.

Inhabitants of our planet are protected from the harmful effects of solar winds by the blanket of atmosphere around the planet. The highly energized particulates do interact with the molecules in the Earth’s atmosphere, compressing the Earth’s magnetic field. This is called a geomagnetic storm.

Scientists suspect that highly energized particles that came from the CMEs released by the sunspot AR3165 cracked open the Earth’s magnetosphere, which puts us at the receiving end of solar material.
