During the next few weeks on some clear moonless early morning, if you are fortunate to be far from any haze and bright lights, keep a close watch on the eastern horizon about two hours before sunrise. Many have been fooled into thinking that it’s beginning of morning twilight and indeed the Persian astronomer, mathematician and poet Omar Khayyam (1050? -1123?) referred to this ghostly glow as the “false dawn” in his poem, The Rubaiyat.
