At like 11:30 in the morning me and some friends saw a circular unknown object flying at low hight leaving a pink trail on the blue sky.It was really wierd cause the same object was seen in another city after too.Unfourtunatley we had no camera with us.It was moving slowly through the sky.

I think it couldnd be made by humanity.It was too wierd.
