a solar stormand european space agency It has been warned that it is “serious” and will hit Earth this week. Its most immediate impact is the disruption of communications and the appearance of spectacular aurora borealis and australis.
The most intense days were Tuesday and Wednesday. as far as he knows nation from sources National Weather Service, Solar storms will continue to impact Earth these days, but their intensity will decrease.
Due to intense solar activity, auroras occurred at unusually low latitudes. New Zealand, Australia, Mexico, Chile, USA, This phenomenon also affects It is affecting communication networks, causing satellite failures and overloading electrical networks.. Despite the risks of this week’s solar event, space companies jeff bezos Blue Origin was forced to postpone the launch of its New Glenn rocket again on Wednesday.
Meanwhile, the European Space Agency, which continues to pay close attention to the development of this phenomenon, says that due to strong disturbances in the geomagnetic state, Lasts for next 24 hours.
The agency estimates that the effects of the resulting geomagnetic storm will be as follows: “strict” and influence Satellites, electrical networks, navigation systems, etc. However, he felt that this event Does not pose a biological risk Delivered directly to people around the world.
When a solar storm occurs, the sun goes through the following sequence of events, but not all elements are clear each time: When a solar flare occurs, the explosion can release as much energy as a billion atomic bombs. A torrent of electromagnetic waves leaves the sun at the speed of light and reaches Earth eight minutes later. This can interfere with shortwave radio communications and cause errors in navigation systems.
Then, less than an hour later they arrive fast solar energy particlesincluding protons, electrons, and alpha particles. This radiation can harm astronauts or damage spacecraft, create a cascade of secondary particles in the atmosphere, and can cause electronic components to fail once they reach the ground.
Flares typically involve massive ejections of ionized gas from the Sun’s outer atmosphere, known as coronal mass ejections (CMEs). EMC creates gusts and shock waves in the solar wind that, if directed toward Earth, can take anywhere from 18 hours to several days to reach us.
When EMC reaches the Earth, it distorts its magnetic field, creating a magnetic storm.
Auroras are produced by huge coronal mass ejections that cause magnetic storms when they reach Earth.
of National Oceanic and Atmospheric Administration The US NOAA said that this solar storm Level 4/5 And it says the arrival of another CME could mean a repeat of the aurora borealis this Thursday.
the sky Mexico On Tuesday night, they were lit up with pale pink and green lights, to the delight of many people who normally have to get closer to the polar regions to see the phenomenon.
Last year saw the first Level 5 geomagnetic storm in 20 years, creating similarly spectacular scenery.
To see the Northern Lights, enthusiasts are advised to look for dark skies away from city lights and carry a camera or smartphone. If not visible to the naked eye, the light may be visible in long exposure photos.
