I glowing light unlike anything I have ever seen moved across the sky a d behind a cloud faster than anything I have ever seen. Not a bright light,only a glowig light. I raised my hand to point to it and my friends said what. Initially I said nothing due to te nature if what I saw. But I had to tell them what i saw. I am 57 years old and have necer seen anything like that. No way a plane or helicopter. I am really amazed at it and amazed no one else saw it.
