High-speed solar wind from a “hole” in the sun’s atmosphere will hit Earth’s magnetic field on Wednesday (August 3), triggering a small G-1 geomagnetic storm.
Forecasters at the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC) predict that “gaseous material is flowing from a southern hole in the Sun’s atmosphere,” According to spaceweather.com.
Coronal holes are regions of the Sun’s upper atmosphere where our star’s electrified gas (or plasma) is cooler and less dense. There is also a hole where the sun resides magnetic field The lines, instead of looping within themselves, beam outward into space. This enables solar material to escape in a torrent that travels at 1.8 million miles per hour (2.9 million kilometers per hour). exploration, A science museum in San Francisco.
On planets with strong magnetic fields, like our own, this barrage of solar debris is absorbed, triggering geomagnetic storms. During this storm, Earth’s magnetic field Very strong particles are slightly compressed by waves. These particles trick the magnetic-field lines near the poles and cause molecules in the atmosphere to vibrate, releasing energy in the form of light to create colorful auroras, which create Northern Lights.
The storm produced by this debris will weaken. As a G1 geomagnetic storm, it has the potential to cause minor fluctuations in the power grid and affect some satellite functions — including mobile devices and GPS systems. It will also bring as Aurora as far south as Michigan and Maine.
More extreme geomagnetic storms can disrupt our planet’s magnetic field strongly enough to send it spinning The satellite is crashing into the earthLive Science previously reported, and scientists have warned, that extreme geomagnetic storms could occur Internet is down. Debris from the sun, or Coronal mass ejections (CMEs), typically take about 15 to 18 hours to reach Earth Space Weather Prediction Center.
The storm comes as the Sun enters the most active phase of its nearly 11-year-long solar cycle.
Astronomers have known since 1775 that solar activity rises and falls in cycles, but recently, the Sun has been more active than expected, nearly twice as many sunspots as predicted. NOAA. Scientists estimate that the Sun’s activity will climb steadily for the next few years, reaching an overall peak in 2025 before declining again. A research paper published July 20 in the journal Astronomy and Astrophysics proposed a new model for the sun’s activity by calculating sunspots in each hemisphere separately — a method the paper’s researchers could use to make more accurate solar forecasts.
Scientists believe the largest solar storm in modern history was the Carrington Event of 1859, which released about the same energy as 10 billion 1-megaton nuclear bombs. After hitting Earth, powerful streams of solar particles fry telegraph systems around the world and create auroras brighter than full light. the moon As far south as the Caribbean appears. If a similar event were to occur today, scientists warn, it would cause trillions of dollars in damage and cause massive blackouts, much like the 1989 solar storm that released a billion tons of gas and caused blackouts across an entire Canadian province. Quebec, NASA said.
