According to the Imena correspondent, on Sunday night, the moon and Saturn will be in one dimension from the point of view of ground observers, and the 17-day moon will pass through the south of Saturn at a distance of four degrees and one arc minute, creating an attractive companion. Comparison is the fact that the dimension or length of the ecliptic circle of two objects is the same; When two celestial bodies, such as two planets (moon and planet or sun and planet) reach a small apparent distance in the sky, the word comparative is used in astronomical reasoning, but in cases where their angular separation is small, the term proximity, companionship, or community is used.

From the coordinates of Larestan Observatory, the companionship of the moon and the planet Saturn in the morning sky will be visible. When these two objects reach a height of seven degrees above the southeast, that is, after the rising of Saturn and the moon (about 23 hours) until 3:34 in the morning, 44 degrees above the southern horizon, they reach their highest point in the sky, then at dusk. At about 5:43 a.m., in a position 34 degrees above the southwest horizon, they disappear in the morning light.

The moon shines in the negative magnitude 12.6 and the planet Saturn shines in the sky with a magnitude of 0.3, and both are in the constellation of Capricorn or Capricorn. When viewed with a telescope, the two objects cannot be in the same field of view at the same time, but can be easily seen with the naked eye or through a binocular camera. In the coming week, Kayhan is witnessing beautiful and amazing astronomical events, which we have conducted an interview with Fatemeh Fakhraeifard, an expert of the scientific team of Larestan Observatory, in order to investigate them further, which you can read below:

When does Thori June meteor shower occur?

Meteor showers occur when the Earth passes through particles left by the passage of comets and asteroids near the Sun. Thori meteor shower will be active from the first to the 11th of July, and the most meteor shower will occur on Sunday, the 6th of July. Whenever the center of precipitation in the constellation of Aquarius or Taurus is above the horizon, it is possible for meteors to be visible.

The epicenter of a precipitation is the point at which all the meteors of a particular meteor shower appear to radiate from that point in the sky. From the location of Larestan Observatory, the center of precipitation is above the horizon almost throughout the night (precipitation is active throughout the night). The center of precipitation reaches its peak in the early hours of the night, the highest point in the sky, at about 21:00; So it's probably a good time to observe after sunset when the focus of precipitation is above the observer's head. The rotation of the earth causes the meteor to enter the atmosphere in the best direction (it is perpendicular to the bottom and in short distances close to the center of precipitation).

Since meteors are close to the center of precipitation at this time and the center of precipitation is above our heads, we can easily observe this precipitation. After midnight is a good time to observe this astronomical event, because the closer we get to the sunrise, the meteors enter the Earth's atmosphere from the side and their speed collects with the speed of the Earth and the meteors with faster speed and higher burning intensity Are visible.

The meteor shower is expected to peak around 3:00 a.m. Monday, July 7, to see the largest number of meteors. Precipitation is at a distance. Approximately at this distance from the meteor shower, the largest number of meteors are observed. On this night, the Moon in a serious constellation is only three days away from the phase of Badr, so the sky is completely clear and it is difficult to see dim meteors. The source of this meteor shower is a comet called 7P / Pons-Winnecke.

Monday - July 7 - Which astronomical event will we witness?

Monday - July 7 - Comparison of the Moon and Jupiter will occur. One night after the moon and the planet Saturn meet, the moon and Jupiter are also in a state of comparison, and the moon is separated by an angle of four degrees and 27 arc minutes from the largest planet in the solar system. The age of the moon at this time will be 18 days and its brightness is about 75%. These two objects are visible in the morning sky and will be fully observable when they are eight degrees above the eastern horizon.

Then at 4:48 in the morning, 50 degrees above the southern horizon, two objects reach their peak in the sky and can be observed until the sky is completely clear. The magnitude of the moon on this night is negative 12.4 and the magnitude of Jupiter is negative 2.7, both of which are in the constellation of Aquarius. Jupiter rises at 23:10 and the Moon at 22:37. This phenomenon can also be observed with the help of a binoculars. On Tuesday night, the two objects are seen in the sky close to each other.

Can we observe the NGC 6633 star cluster this week?

Monday - July 7 - The open star cluster NGC 6633 with a magnitude of 4.6 is located in the constellation Marafsa. It reaches its highest point in the sky around midnight and can be seen in most parts of the world from six degrees and 30 minutes north. In fact, it has the best locations for observation between latitudes 76 degrees north and 63 degrees south. As it gets dark, it will appear in the sky at approximately 20:59, 30 degrees above your eastern horizon, and then reach its highest point in the sky at around 00:57 in the morning, 68 degrees above the southern horizon. It disappears in the morning light at about 04:55 in the morning at a position 30 degrees above the western horizon. Of course, this mass with a magnitude of 4.6 is very weak and can not be seen with the naked eye in the sky despite the moon, but it can be seen using a binoculars or a small telescope.
