A crack remained open in the Earth’s magnetic field for 14 hours

On Thursday, July 7, 2022, photographers across the United States and Canada had the chance to capture a breathtaking sight. A crack opened up in the Earth’s magnetic field that lasted nearly 14 hours, allowing solar winds to enter and cause a colorful aurora in the sky.

Although a crack in the magnetic field seems dangerous, it is actually quite normal. “We discovered that our magnetic shield is full of drafts, like a house with a window left open during a storm,” said Harald Frey, lead author of a 2003 study on the discovery. by the co-rotating interaction region (CIR) of the Sun, which is sometimes launched in the direction of the Earth.

However, while most magnetic fields are thought to be short-lived, this one lasted for several hours, leading to a G1-class geomagnetic storm. Fortunately, however, this event did not cause power outages or problems with the satellites, which can sometimes occur during these cracks in the magnetic field. Instead, leaking solar winds produced beautiful aurora borealis over the United States and Canada.

On Thursday, July 7, Earth experienced a crack in its magnetic field that lasted 14 hours.

This has allowed people in the United States and Canada to see beautiful Northern Lights in the sky.
