Preface: Auroras are a visible manifestation of geomagnetic storms. Geomagnetic storms are disturbances in Earth’s magnetosphere caused by the interaction of charged particles from the sun (the solar wind) with Earth’s magnetic field. Auroras typically appear in high latitudes, including northern North America and parts of Asia.
Background: The Sun’s corona and heliosphere, while constantly present, are often unseen. The corona, the Sun’s outermost atmosphere, is extremely hot and extends far into space. This hot gas is flung outwards by the Sun, forming the solar wind, which creates the heliosphere, a bubble surrounding our solar system. In June 2025, NASA’s PUNCH (Polarimeter to the Unseen Corona and Heliosphere) mission has been actively observing coronal mass ejections (CMEs). These observations, including detailed images from the Narrow Field Imager (NFI) and Wide Field Imagers, are providing new insights into the origins and paths of CMEs, helping scientists better understand and predict space weather.
Observation: Due to the high-speed flow of the coronal hole, NASA has issued a G2 (moderate) geomagnetic storm warning on June 14.
Ref: Geomagnetic storms, disturbances in Earth’s magnetic field caused by solar activity, can impact our planet in various ways, primarily affecting technology and infrastructure. While not directly harmful to humans due to our planet’s protective magnetic field and atmosphere, they can disrupt communication systems, navigation, and power grids.
