Day 1: you see a glimmering light in the sky that is barely perceivable to the naked eye

Day 2: the same shiny object is now slightly more noticeable.

Day 3: The same shiny object, is still there and seems to be leaving a trail
along it's path, it appears ever so slightly closer to you

Day 4: It is clear it's getting closer but nobody in the news or media talks about it

What would you do next? People see it, but nobody really cares or gives it a second thought.
