I was downtown when i looked into the sky and i saw more than 10 lights that looked like stars. i wasn't surprised because the day before i saw what i saw today. the whole event lasted about 10 minutes. i know they're not satellites launched by the spacex company. because the satellites of spacex companies are not that far away and move from europe north to south, while these lights move northwest to northeast, in formation one behind another and spacing was large. the objects looked like stars and didn't flash like the planes did. both of them did not disappear as they appeared, from where they appeared they only began to shine, and they disappeared by stopping glowing.
