See the Sha’ban Crescent on Thursday without a telescope; Moment of meeting the moon with the Sun – | Iranian and world news

Ali Ebrahimi, a crescent observer and a member of the Amateur Committee of the Iranian Astronomical Association, in a conversation with Mehr reporter, examined the importance of the crescent monitoring and the conditions of seeing the crescent of Sha’ban and said: Date registration is used and the crescent moon is used to start the lunar moon on the western horizon. The lunar calendar has been used for thousands of years, and now in Islam, many of the events of Islam have been written based on this calendar. Therefore, seeing the New Moon Crescent has its own charm.

He added: During the 6 months, there are different crescents; Some of these crescent may be visible before sunrise and others after sunset and even some throughout the day. The characteristics of the crescent moon always show us what the conditions are to see and whether it is not seen and if seen we need the naked eye or optical tool.

Ebrahimi emphasized that it was necessary to examine its characteristics to see the crescent. The first thing we do is to look for a new moon based on an astronomical calendar before the crescent observation begins.

He explained the time of the new moon: In the new moon, the moon visits the sun and is not seen in the sky for a while. This moment coincides with the crescent at 9:30 pm Wednesday, February 10th. After this moment, as the moon moves around the Earth, it gradually departs from the sun and formed the crescent.

Ebrahimi went on to say that the day of February 2, which coincides with the twenty -ninth month of Rajab, will be a good time to see the crescent of Sha’ban. At this time, we are examining the western horizon of the moon’s observation parameters. For example, in the city of Tehran with sunset which will be around 9:50 pm, the moon is about 2 degrees Celsius and separation is separation. His angle The sun is approximately 2 degrees. At this time, one and a half percent of the moon’s surface is lit, and after sunset, we have an hour to find the narrow crescent of the moon before sunset.

He also pointed to the use of planets in the sky to observe the crescent moon, adding: “To search for the moon, we can use the planets that are on the western horizon these nights, such as Venus and Saturn, even after sunset.” These planets can be a good indicator for finding the crescent.

Ebrahimi pointed out that astronomers always use the characteristics of crescent and celestial bodies next to the moon to find the crescent on the horizon. They specify an area on the horizon where the crescent is present and the work Search They do after sunset.

The crescent observer said at the end: The sight of the Sha’ban Crescent with the naked eye is a good practice to gradually be able to see the crescent of Ramadan this year in March.
