What is Aurora Negro?
Aurora Negro, or black aurora, is a fascinating phenomenon that appears within the northern and southern lights. Unlike the vibrant colors typically associated with auroras, black auroras present as dark regions that seem to interrupt the glow, creating a mysterious and captivating effect.
Characteristics of Black Aurorae
Black aurorae can manifest in various forms, including dark rings, curls, or blobs. These features add a unique dimension to the auroral display, enhancing its beauty and mystique.
They occur in specific ionospheric conditions, characterized by areas with a scarcity of negatively charged particles. This results in the upward repulsion of electrons, which effectively create these dark patches within the otherwise luminous aurora.

Scientific Insights
Exploration into black aurorae has been greatly enhanced by the European Space Agency’s Cluster spacecraft. These investigations provide invaluable data, shedding light on the specific ionospheric conditions that lead to the creation of black aurorae, thus garnering substantial scientific interest.
The phenomenon of Aurora Negro continues to intrigue both sky watchers and scientists alike, as it represents a unique interplay of natural forces that captivates the imagination and challenges our understanding of the ionosphere.
