What is the timetable for observing the astronomical beauty on April 5, 2020?

April is a season of flowers and birds, which is very suitable for going out for an outing, and the sky in April is also competing. Then let's use constellation knowledge to reveal the observation of the sky in April 2020. Astronomical beauty schedule on April 5?

1.3 On April 5th, Venus met the Pleiades star cluster and competed to shine; 2. On April 8th, the biggest full moon in a year appeared; 3. In the early morning of15 to 16, the moon successively met Jupiter, Saturn and Mars, and staged "Three Stars Accompanied the Moon"; On April 22, the Lyra meteor shower "dressed up" the night sky; On May 28th, Venus is the brightest in the whole year.

Observation in April 2020: On April 3, Venus and the Pleiades will meet, and on April 3, Venus and the Pleiades will meet. Dr. Wang Yumin from Beijing Ancient Observatory said that Venus was a dark star this month, and the sunset was in the southwest sky, with a height of about 40 degrees. On April 3, Venus was only 0.3 degrees away from the Pleiades cluster in Taurus. The Pleiades cluster, also known as Seven Sisters cluster and M45, is commonly known as the "blue question mark" and can be observed with naked eyes or low-power telescopes. "The next meeting of Venus in the Pleiades will be three years later, but it won't be as close as this one, so we should seize this opportunity," Wang Yumin said.

April 8th Super Moon On April 8th, the "Super Moon" will land in Tianyu again, and this time it will be the biggest full moon this year. Wang Yumin introduced that on April 8, the moon will pass through perigee at 2: 09, and the full moon will be at 10: 35. Because the time difference between the full moon and the moon passing through the perigee is only more than 8 hours, it has become the biggest full moon this year. At the full moon, the distance from the earth to the moon is about 357,029.882 kilometers, and the apparent diameter of the moon is about 33.46 minutes, about10,31,which is the smallest full moon this year. Wang Yumin reminds readers who like taking pictures that they can plan to take the desired images with their favorite features or landscapes when the elevation angle of the moon is low after the moon rises.

April 15 The Moon Accompanied by Three Stars will be a unique beauty in the night sky from April 15 to April 16. In the early hours of these two days, the moon will meet Jupiter, Saturn and Mars successively. First of all, Jupiter will be in close contact with the first quarter moon, and at the lower left of the moon, there will be yellow Saturn and red Mars. At 7: 05 on June 5438+05, Jupiter combined with the moon, and Jupiter was 2.0 degrees north of the moon; 15, 17: 08, Saturn is in conjunction with the moon, and Saturn is 2.5 degrees north of the moon; 16, 12: 33, Mars and the moon merge, and Mars is 2.0 degrees north of the moon. At this time, it was the last quarter of the moon, and four bright celestial bodies formed a lively scene of "dependence and companionship" in the southeast sky.

April 22nd Lyra meteor shower On April 22nd, Lyra meteor shower will usher in a great. Wang Yumin introduced that the Lyra meteor shower in April was a moderate-intensity meteor shower, and the maximum time this year is expected to be around April 22nd 14: 40. Therefore, the observation time can start from midnight on the 22nd to dawn on the 23rd. The phase of the sun and the moon is new, without the interference of moonlight, which provides favorable observation conditions for the Lyra meteor shower in April this year. "Although there are not many meteors in this meteor shower, there are occasional fireballs."

On April 28th, Venus reached its maximum brightness. Wang Yumin introduced that Venus is the brightest natural celestial body except the sun and the moon in the whole sky, and it can be seen at its brightest in the daytime. Whenever Venus is far east or far west, its angular distance from the sun is the largest, which is most beneficial for observation. However, a long distance is not the brightest time for Venus. After a long distance, Venus will be closer to the earth, and its apparent diameter and brightness will increase. However, due to the phase change of Venus, it is shrinking into a "crescent" shape. So there is a moment in the middle, Venus reaches the "brightest", and then the brightness begins to decline. Similarly, at some point before the western sky, the brightness of Venus reached the "brightest" again. Venus is the brightest twice this year. The first time was at 2 o'clock on April 28, when Venus was 40 degrees east of the sun and its apparent brightness was -4.7. The second time was on July 10/6, when Venus was 40 degrees west of the sun and the apparent brightness was -4.7. Observed with an astronomical telescope, Venus at this time is crescent-shaped with an apparent diameter of 37.4 seconds.
