In fact this was a practice for next month crescet that is critical. I was the first man who could observe this crescent with naked eye. I could observe the crescent only for 10 seconds and at next because of very low thickness of the crescent we couldn’t observe the crescent any more."

  • Saudi: ICOP member, Mr. Saleh Al-Saab said: "Unfortiunately no instroment was available this time, and the naked eye was not enough to see the crescent. Also I am so sorry for not being able to share last month observation because I was out of the country."
