CAIRO - Egypt and the Arab region will witness a partial solar eclipse on November 25, the fourth eclipse this year, the head of the National Institute for Geophysical and Astronomical Research said. "This eclipse coincides with Muharram, the first month of the Islamic Calendar," Hatem Auda was quoted by the official Middle East News Agency as saying. The current month, Dhu'l-Hijja, which precedes Muharram, is 29 days long. Auda added that the November 25 eclipse will be the last in 2011. Egypt has already had three partial eclipses this year: a visible eclipse last January, and two invisible eclipses in June and July.
