What triggered the rare auroral arc in Ladakh's sky recently

1. Recent research suggests that the rare auroral arc spotted in Ladakh's sky was triggered by an interplanetary shockwave. 2. Interplanetary shockwaves occur when high-speed solar winds collide with the Earth's magnetic field. 3. The collision of these solar winds with the Earth's magnetosphere can lead to disturbances in the ionosphere, resulting in auroras appearing at lower latitudes, such as Ladakh. 4. The particular geomagnetic conditions at the time likely played a role in allowing the auroral arc to be visible in Ladakh. 5. Scientists are continuing to study the specific mechanisms that led to this unique natural phenomenon to better understand the Earth's complex interactions with space weather.
