Premature dawn around the globe

This paper summarizes four books with more than 1700 pages that report on our research since 2017. These books are available on the Amazon network worldwide. We use thousands of morning twilight data captured using modern sensors from around the world. The visual shreds of evidence that is easily perceivable even by ordinary people is the strength of our report. The visual evidence is in the form of original photos and the results of versatile image processing techniques. We genuinely developed the computing algorithm for twilight data processing to conclude that the world’s dawn occurs when the sun is 9o to 13o below the local horizon. This result is far from the official stipulation of the world Muslim organizations, which consider dawn to have appeared when the sun was at a position of 15o-20o below the horizon. We hope that the results will improve the definition of dawn’s birth, which marks the beginning of the Fajr prayer for 1.8 billion Muslims worldwide.
