A burst of Perseids meteors expected to be seen in the sky Wednesday night
The International Astronomy Center expects that the sky will witness on Wednesday night from Thursday 12 to August 13 a burst of meteors called "Perseids". The peak of the storm will be on Wednesday between one in the afternoon and four in the afternoon GMT, which makes the most appropriate night to monitor this shower from the Arab world is a night Wednesday to Thursday.
Usually an hour at peak time sees between 50 and 75 meteors as a bribe, if the observation is from a dark and appropriate place, but in the case of observation from bright places inside cities or monitoring at a time far from the peak of the rain, the observer may not see more than a few meteors only at the best Adverbs.
Engineer Muhammad Shawkat Odeh, Director of the International Astronomy Center, a member of the International Meteors Organization, confirmed that the Perseus group will shine in this period around ten in the evening, which means that Perseid meteors begin to appear around ten in the evening, but their number is very little at this time and with the passage of time the number of meteors will start to increase. To become more noticeable after midnight and will increase more with approaching the time of dawn, so that the time before dawn is the most visible time for meteors in general.
And he said: “The radiance point of this storm is located in the northeast near the Perseus group, and the point of radiation is an imaginary point from which all meteors appear to be emanating from it, and although meteors appear to be emanating from it, meteors can be seen anywhere in the sky and it is usually preferred to look About 45 degrees away from the point of radiation and 45 degrees away from the horizon. "
He added: "Meteors are dust grains that enter the Earth's atmosphere and melt and evaporate as a result of their friction with it and ionize a part of it. As a result, we see them in the form of a bright line moving rapidly in the sky for a period of seconds or a fraction of a second. It is rare for the diameter of the meteor to exceed the diameter of a grain of dust and range It is between 1 mm to 1 cm only, and the speed of the meteor when it enters the atmosphere is between 11 and 72 km per second, and the meteor begins to appear at a height of approximately 100 km from the surface of the earth, and the number of meteors that fall on the ground is about 100 million per day, most of which are invisible to the eye. The abstract.
And meteors do not pose any danger to the surface of the earth at all, even if it is in the form of a storm, all the meteors disappear before they reach the surface of the earth, but there is a real danger that dust particles may pose to the satellites orbiting the Earth, which number about 500 working satellites.
