Virginia Mid-Latitude Aroura - Directly Overhead - October 2024

Generally, not visible, SAR arc was very visible. SAR is an abbreviation for Stable Auroral Red Arcs. Although SAR Arcs are not the Aurora itself, they form during geomagnetic storms. They occur when solar particles interact with oxygen in the ionosphere, heating the oxygen and generating a stable red glow above our heads, hence the name “Stable Auroral Red.”
