Solar System Eruption

When do solar eruptions occur?

Such events are more common during solar maximum (or peak of the solar cycle) but are less frequent during solar minimum (or low point of the cycle). Sunspots, or dark “blemishes” on the Sun, also increase during solar maximum and mark magnetically active regions on the Sun, which give rise to solar eruptions.

What causes a solar flare?

In addition, there are a large variety of phenomena that are driven by the variability of the sun over periods ranging from hours to years. Solar flares are large eruptions of electromagnetic radiation from the sun. They can last minutes or hours and can cause increased ionization in the lower layers of the Earth’s ionosphere.

How fast do solar eruptions travel?

Solar eruptions can accelerate charged particles — electrons and protons — into space at incredibly high speeds, initiating a radiation storm. The fastest particles travel so quickly they can zip across roughly 93 million miles from the Sun to Earth in about 30 minutes or less.

How does a double solar eruption affect the Northern Lights?

Here’s how it works. A rare double solar eruption fueled a spectacular display of the northern lights overnight — and more auroras could be on the way. Last weekend, two separate solar eruptions sent a pair of coronal mass ejections (CMEs) — clouds of solar plasma and radiation — hurtling towards Earth.

Does the Sun have a X-class solar flare?

The sun has certainly had a busy weekend. Not only has our star fired off multiple M-class solar flares, and coronal mass ejections (eruptions of magnetic field and solar plasma), but now it's topped it all off with a colossal X-class solar flare.

How did solar eruptions affect Northern Lights?

Solar eruptions created a northern lights display in North America and Europe overnight, with more auroras expected through Thursday. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.
