The first day of ramadan
The Astronomical New Moon is on Friday September 22, 2006 at 11:45 Universal Time
Looking at the visibilty curve one can understand that the moon is impossible to be seen in any continent, although it is possible to be seen near the International Dateline southwest of Hawaii by telescope on September 22. On the same day at west coast of North America, the moon will be about 14 hours old, and about 1 degree above the horizon at sunset time, and will not be visible in North America.
On September 23, 2006, the moon will start to become visible, by telescope from New Zealand and Australia, and by naked eye from Southern Africa, South & Central America. If atmospheric conditions are perfect, it can be seen in some parts of North America also on Sep. 23, otherwise it will be seen in North America on Sep 24.
So if we consider the beginning of lunar month by sighting of new moon , and paying attention to this point that Ramadan crescent is not visible on Saturday in the most parts of Asia and Europe even by the most powerful optical aids , Sunday will be the last day of Shaban and Monday will be the first day of Ramadan .
But this crescent will be visible on Saturday by naked eye in central and southern parts of Africa and South & Central America ,if the weather would be clear , then Sunday could be the first day of Ramadan for the people of these areas.
Finding this crescent on Saturday needs optical aids in some parts of North America, New Zealand, east of Australia, Malaysia and some other regions in south and southeastern Asia.
Also Ramadan crescent could be visible by a 7*50 bin , in North Europe during the day on Sep. 24 when the moon and the sun are both above horizon .
Iranian observers are preparing themselves for this crescent and looking for ideal observing sites. Among all these, observers from Isfahan who had observed new crescent moon of December 2nd, 2005, are more hopeful to see this similar crescent on Saturday in central regions of Iran by their powerful optical means.
