According to forecasts, there's a 60% chance that the aurora borealis will be observable on the night to Friday as well.
The northern lights are often called kāvi in Latvian, a word related to kaut - slay - or kauties - to fight. Superstition has it that red northern lights are either dead soldiers fighting across the arch of the sky, or a sign that war is to come.
Users on Twitter shared their photos of the kāvi:
Vienu brīdi debesīs bija iespaidīgi ziemeļblāzmas gaismas stari, šķita, ka tur milži cīnās ar gaismas zobeniem. pic.twitter.com/0104OlLFPa— Ilgonis Vilks (@astrovilks) October 7, 2015
Tie tik bija KĀVI! Ziemeļblāzma Carnikavā, 7. oktobra vakarā. pic.twitter.com/mJ0t8KzNiL— Ivo Dinsbergs (@orkaans) October 7, 2015
