The purpose of this installation is a mystery to me, but it’s bright, white, and creates significant lightpollution over the small village of Tijarafe on La Palma’s western coast. Oddly enough, it’s mounted on a window of a public education center (CEO Tijarafe). This is what it looks like at night:
Hard to see in this image, the installation consists of a pattern of bars and crosses (discernible in the lens reflection) which turn on and off every couple of seconds. It may be a leftover Christmas decoration, but I didn’t notice it before January 14, when it was active even after midnight. The images above and below were taken around 22:40 local time on January 15.
From a distance of 2,5km, the lights are easily visible:
The white LEDs contrast with the light-pollution friendly amber colored streetlights. They cause glare and noticable skyglow over Tijarafe.
