I was at my computer, then the neighbors dog started barking and didn't stop, i checked my CCTV for anyone in front of the house but saw nothing, then i decided to see trough the window, and i saw a red line on the sky with my naked eyes. I went outside the house check if was some kind of reflection in my window, but the object still was there. I went inside, grabbed my binocullars (Sakura 10x-90x50) and observed the object i sketched in the attachment.
