Earth Dodges Solar Flare Bullet – Another Powerful Eruption Follows Historic Solar Storm

By: Sam Watanuki | Published: Jul 02, 2024

The sun has been particularly active lately, emitting powerful solar flares. On Tuesday, it released another significant flare, just a week after a severe solar storm.

This recent activity has scientists and space weather enthusiasts on high alert, as the sun’s 11-year solar cycle reaches its peak.

Largest Solar Flare Since 2017

The latest solar flare is the largest detected since 2017. Classified as an X-8.7 magnitude, it surpasses the strength of previous flares.

NASA classifies these flares from B-class, the smallest, to X-class, the largest. Each class represents a ten-fold increase in energy, with X-class flares being the most powerful.

Impact on Earth’s Technology

Powerful solar flares can disrupt radio communications, electric power grids, and GPS signals. The recent solar storm caused some power grid irregularities and interfered with GPS signals, even affecting farming equipment.

The SDO plays a crucial role in observing the sun, providing valuable data to help predict and understand solar events. This data is essential for preparing and mitigating potential impacts on Earth.

Geomagnetic Storms and Auroras

The solar storm from the previous week sent coronal mass ejections (CMEs) toward Earth, creating a powerful geomagnetic storm.
