Aurora Borealis in Leiden yesterday evening! Big thanks to @riederSteven Rieder for notifying!

#AuroraBorealis #NorthernLights #Leiden #Sleutelstad #Academiegebouw #MolenDeValk #Windmill

Cityscape at night. A green flame extends from the middle of the picture to the top-right. Left of it the smoke from a high chimney travels to the left. Foreground shows domestic buildings in an orange-yellow light from the streetlights

Another cityscape at night. A tall traditional windmill on the left of the picture, with in the sky, close to the horizon, a soft band of green. Higher up in the sky a soft band of red. The windmill is lit in a soft yellow glow. Bare trees and streetlights are seen in the foreground.

Picture taken from a train platform. Train and power lines in the foreground. Background shows a green band of light near the horizon. It's given texture by some small bands of grey clouds. Higher up in the sky are tall curtains of red.

A typical Dutch canal with historic houses and yellow streetlights. On the left we see the tower of the former convent that is now Leiden University's Academic Building. High up in the sky, near the Zenit, is a bright diagonal green flare.
