Astronomical researcher Ali Al -Hajri said that the crescent of the month of Dhu al -Qi’dah for this year 1446 AH will be very easy and suitable for monitoring the crescent with astronomical telescopes and perspectives directed and difficult for the naked eye in the case of serenity of the air and a professional observer on Monday, April 28.
Al -Hajri explained that the moon of the month of Dhul Qi’dah will be associated with the sun, God willing, next Sunday evening, April 27th, at 11:04 pm for the superficial account, the Kingdom of Bahrain, to be impossible to monitor it in all countries of the Arab world for only two reasons in order, namely the decay of the moon before the sunset and the occurrence of conjugation in the evening period, and after sunset, while the crescent will be easy in monitoring by astronomical telescopes or endoscopy For a professional observer, and it is difficult for the naked eye a day after its association with the sun, which is on Monday, April 28, on the condition of the weather, to stay in the moon in the sky of Bahrain for 56 minutes, before its dismissal at 07:04 pm, as the lifetime of the moon in this period is 19 hours and 4 minutes, and at an altitude of 10 degrees and 16 minutes, and at the angle of elongation between the moon and the sun equals 11 degrees and 23 minutes, to reflect 0.99% of the sunlight on the surface of the moon Lighting and negative AG 5.12, and with a thickness of the crescent equals only 20 arc seconds.
The stone attributed the difficulty of monitoring the moon with the naked eye in Bahrain, as the moon cannot reflect a large amount of sunlight on its surface in relation to the Earth due to the small angle of the elongation, despite its height and the period of its survival appropriately, which is one of the direct requirements to achieve the conditions of vision in kind, as it will be associated with the time of the initiation for less than 24 hours; Thus it will be possible to be photographed easily in the case of serenity.
