I had just exited the T in Harvard Square, and turned the corner on to Mt. Auburn St., when a shine caught my eye. I looked up, and saw what looked like a silver boomerang totally still, high up in the sky. I blinked because I thought my eyes were blurry, then turned around and saw the moon and a star (below it) very clearly...I turned back around, and the object was still there. It stayed completely still, and was shinier on the right side than the left. An airplane came from behind where I was standing, and flew low and beneath it, and I slowly realized my eyes were not playing tricks on me...the object was absolutely still and remained in the exact spot, with a slight haze around it. At first, I thought it was my eyes that were blurry and I simply didn't believe what I was seeing. I turned around, checked my eyes, and returned to still see it, and stared in disbelief. I felt scared, overwhelmed and sad all at once. I thought I should call someone or grab a stranger and point it out, but it took me telling someone else about it to begin to realize how real it was. It took hours for the event to actually sink in, and it feels unreal. I drew a picture...I wish I could've captured it on film. I actually can't do justice to how I feel right now...I had to search for somewhere to tell someone, and found this site. After probably a minute and a half, I turned the corner to my apartment, and when I looked back to check and see if it was still there, it was gone. It was there, then it disappeared. This happened at twilight, a quarter to 6pm, in a clear, cloudless sky.
