Double satellite flyby against FACT Telescope

| | | |


In this colorful startrail captured facing to northwest region, we could see behind FACT Telescope silhouette, the trail of a double satellite flyby, possibly related to the Naval Ocean Surveillance System (NOSS) satellite formation, each having two or three satellites in close proximity to one another. Normally these satellites are relatively dim to the unaided eye, but on occasion they brighten sufficiently to be easily seen in a dark sky, like occured in the sky of Roque de Los Muchahos observatory, in La Palma, Canary Island.

The image was taken in Observatorio del Roque de los Muchachos (ORM) situated on the edge of the Caldera de Taburiente National Park, 2.400 m. above sea level, on the island of La Palma, Canarias, Spain. It is home to one of the most extensive fleets of telescopes to be found anywhere in the world, and where 15 telescopes from 19 nations use the best night sky in Europe to explore the cosmos.
