It is understood that in February 2019, there will be many celestial phenomena of planetary moons, and it is expected to see the super moon. On February 19, the Lantern Festival can watch the largest full moon of the year.
The best observation time for the 2019 Lantern Festival super Moon: around 23:54 on February 19, 2019
As the Spring Festival is approaching, Dr. Wang Yumin of the Beijing Ancient Observatory introduced that there will be many celestial phenomena of planetary moons in February. On the day of the Lantern Festival on February 19, you can see the largest full moon of the year.
"Super moon" on the Lantern Festival
'because the moon passed perigee at 17:03 on February 19, the time difference between the full moon and the time when the moon passed perigee is only 6 hours and 51 minutes, so the distance between this full moon and the earth is the closest of all the full moons in the year, which is the largest full moon of this year, and the apparent diameter of the moon is 33 & prime; 29″。' Wang Yumin said that this year's' minimum full moon 'occurred on September 14, when the full moon just passed through the apogee, with an apparent diameter of 29.6 & prime;, The annual 'maximum full moon' on February 19 will be about 13.8% larger than the apparent diameter of the 'minimum full moon'. This day coincides with the Lantern Festival. You might as well come out to watch the 'big moon'.
Mercury should be observed at the end of February
On February 27, Mercury will be far east, which is a good opportunity to observe mercury for the first time this year.
Wang Yumin explained that Mercury has become the most difficult to observe among the five planets because it is too close to the sun. From the earth, when the angular distance between mercury and the sun reaches the maximum, it is called "great distance". It is called "great distance east" in the east of the sun and "great distance west" in the west of the sun. They usually appear three times a year. On February 27 this year, mercury set an hour and a half later than the sun and appeared above the horizon slightly south of the West 16° At that time, if the weather is fine, mercury can be seen emitting a faint light in the hazy twilight.
Big planets can be seen in the morning and night
Wang Yumin also combed the dynamics of major planets in the solar system in February for lovers who want to observe planets.
In the evening of February, you can see mercury in the southwest at sunset; Bright Mars can also be seen in the southwest sky after sunset and set at about 22:00.
In the early morning of February, you can see Venus as the morning star in the southeast sky, 'during which Venus further approaches the sun, and the horizon height gradually decreases from 24 & DEG at the beginning of the month; It gradually drops to 18 & deg; at the end of the month;, The brightness is about - 4.2, and the observation conditions are still good '; Jupiter rises from the southeast at about 2:30 a.m., with a brightness of about - 2.0 and can be seen in the middle of the night; Saturn rises at about 4:30 a.m. and appears in the southeast before sunrise. The brightness is about 0.6. There is not much observation time.
