1. I was out in my garden2. The lights3. Plane4. It went in the night sky from north towards south with higher speed than a plane. The lights had a strange way of flashing. I have never seen before a plane or other object doing that. I took a photo because I thought it was interesting. 5. I went back in the house to see the photos and I enhanced every image of the stars I took photos of (I was taking photos of the sky) and than I saw this photos. I felt normal, not scared. I started googling what I saw. 6. It went out of sight like any other normal object in the night sky.
