Happy New Year !!

When to Observe ?

The geocentric new Moon will occur on Friday 16 April 1999, at 04:22 UT. The program Moon Calculator by Dr. Monzur Ahmed -according to Ilyas' criterion- showed that the crescent will be visible by naked eyes on 16 April some where starting from the eastern coast of South America. And so, countries west of this area will be able to see the crescent on this day. However, using telescopes, the crescent will be seen in more eastern areas. Thus, arrange for observing the crescent after the sunset of 16 or 17 April.

Results of seeing the crescent, and the first day of Muharram in different countries will be added here as we receive the reports from ICOP's members. If you wish to be a member in ICOP, or to know more about it, kindly click here.
