Earthlings better brace for geostorms on August 18 as a phenomenon called Cannibal Coronal Mass Ejections caused by the Sun is likely to result in power grid fluctuations, impact satellite operations, migratory animals, and also produce auroras.
As the Sun approaches its solar maxima (a phase of maximum activity in its 11-year solar cycle), a cloud of dark plasma erupted on its surface on August 14 which released a Coronal Mass Ejection (CME), Weather.com reported.
The CME--a huge cloud of solar material that erupts from the Sun--has the power to affect Earth's magnetic field and on August 15, another CME was released right behind the first one.
According to NASA, CMEs can carry the mass of over 250 elephants and has the energy of 75 trillion lightning strikes. And, as per the publications, the two CMEs are set to hit the Earth together on Thursday, August 18, according to US's National Oceanic and Atmospheric Administration forecast model.

Referring to the dark plasma eruption, Spaceweather.com stated, "Travelling faster than 600 kmps, the plume tore through the Sun's outer atmosphere, creating a coronal mass ejection (CME). Images from the Solar and Heliospheric Observatory (SOHO) confirm that the CME has an Earth-directed component."
The CMEs could result in minor to moderate geomagnetic storms on Earth. Minor geostorm or G1 can cause weak power grid fluctuations, affect satellite operations and migratory animals.
Moderate geostorms or G2 are more intense and can result in voltage alarms in high-altitude power systems and even cause transformer damage. They can also have an impact on spacecraft operations.Read more: Top scientist tweeted photo of ‘distant star’, later admitted it was a sausage slice
