Aurora Borealis another name for Nothern Lights — is a quite rare event for Luxembourg's latitudes. It can be observed here approximately once every 10 years! Nevertheless, this fascinating natural phenomenon appeared in the night sky quite recently.
French citizens were able to admire the lights on Sunday night, while Luxembourgers experienced them on Monday/Tuesday night. Residents of Rambrouche were lucky enough to actually see the lights in the sky.
Two factors must coincide for the northern lights to appear in more southern latitudes: a powerful solar flare and a lucky direction of the particle release. More northern countries, such as Norway or Finland, observe this phenomenon several hundred times a year.
