From New York City, "I noticed a star of unusual brightness. It seemed to be flickering from red, to blue to green to white."
From England: "Finally I find someone else who can see it. I see it also and when I looked in my telescope it made me feel ill. Its weird looks like a cell or germ it flickers red and blue. It changes shape and when I look at it I get this creepy feeling like it knows I'm watching. I'm in northeast England and it becomes visible just after sunset."
From Spain, "we were traveling north on the Alicante-Valencia highway, close to Denia. It was after sunset and we were surprised to see a very bright star (the brightest star one can see in the sky) that pulsated with different colors." Thanks to our regular reader M.
