Yesterday, March 20, it was reported that Earth could experience a lightning strike from the coronal mass ejection (CME) that entered today. While astronomers monitor its evolution, more disturbing developments have been seen in the sun. NASA’s Solar Dynamics Observatory has detected a large hole in the sun’s atmosphere blowing out streams of solar wind. This solar wind is expected to reach our planet between March 23 and 24, and may cause another violent solar storm. Things could go wrong if there was a CME coming in that day because the resulting effects would be compounded by the influence of the solar wind. See details.
is evolution the By SpaceWeather.com noting on their website, “A massive hole has opened up in the sun’s atmosphere, and is spewing streams of solar wind toward Earth. It’s a ‘coronal hole’ – a region in the sun’s atmosphere where the magnetic field opens up and lets the solar wind escape.” “.
The solar wind will soon hit the earth
Although solar wind hitting Earth is a very common occurrence, the timing makes it a cause for concern. As this fast-moving solar wind wave is expected to strike a few days after the vernal equinox, Earth will be especially vulnerable to it due to the cracks that form in its magnetosphere. This will produce strong solar storms in general. It can get worse if any incoming CME crashes into it. For that matter, not even a G2 or G3 class solar storm is out of the question.

Typically, solar storms that are so intense display an intense aurora borealis. But don’t be fooled by the display of light as it can cause great damage to our infrastructure. These solar storms can destroy satellites, disrupt cell phone networks and Internet services, cause power grid failures, and damage sensitive terrestrial electronics.
The Role of NASA’s Solar Observatory
The NASA Solar Observatory (SDO) carries a full suite of instruments for observing the sun and has been doing so since 2010. It uses three important instruments to collect data from various solar activities. They include Helioseismic and Magnetic Imaging (HMI) which performs high-resolution measurements of the longitudinal and vector magnetic fields across the sun’s visible disk, the Extreme Ultraviolet Variation Experiment (EVE) which measures the extreme ultraviolet radiation of the Sun and Atmospheric Imaging (AIA) which provides continuous observations.
