The category G4 watch from NOAA’s Space Weather Prediction Center — the second such alert issued this year — warns of the possibility of a solar flare for Thursday and Friday, with a resulting coronal mass ejection from the sun that could disturb Earth’s electromagnetic field.

Scientists can infer the value of the QGP's electrical conductivity from how much the electromagnetic field deflects charged particles such as electrons, quarks, and protons.

National Oceanic and Atmospheric Administration issued a severe geomagnetic storm watch, warning that a concentration of energy flaring from the sun could disturb Earth’s electromagnetic field.

A geomagnetic storm happens when energy from solar wind is transferred into the electromagnetic field around Earth.

A geomagnetic storm happens when energy from solar wind — the high-speed current of atomic particles the sun is constantly flinging into space — is transferred into the electromagnetic field that surrounds Earth.
