A year is about to pass, a new year is approaching. Let’s find out what interesting astronomical events await us in June 2021.
This ephemeris document is mainly translated from the Seasky site, and also references many reputable scientific sites such as Earthsky, NASA, Time & Date, etc. The times of astronomical events in the article are all converted to Vietnamese time.
June 10 – New moon
The Moon will be on the same side of the Sun as Earth and will not be visible in the night sky. This phase will take place at 5:54 p.m. This is the best time of the month to observe faint objects such as galaxies or star clusters, as it is not affected by moonlight.
June 10 – Annular solar eclipse
A coronal solar eclipse occurs when the Moon is too far from Earth to completely cover the Sun. This leads to the appearance of a dark ring of light around the Moon. The solar corona will not be visible during a coronal eclipse. The phenomenon will be limited to the far east of Russia, the Arctic Ocean, west Greenland and Canada. The partial eclipse will be visible across the northeastern United States, Europe and much of Russia. (NASA map and eclipse information) (NASA interactive Google map)

June 21 – Summer Solstice
The summer solstice occurs at 10:21 a.m. Earth’s North Pole will be tilted toward the Sun, the object will reach its northeasternmost position in the sky and will be directly above the Tropic of Capricorn at 23.44 degrees north latitude. It is the first day of summer (summer solstice) in the Northern Hemisphere and the first day of winter (winter solstice) in the Southern Hemisphere.
June 25 – Full Moon, Super Moon
The Moon will appear on the opposite side of the Sun from the Earth and its surface will be fully illuminated. This phase took place at 1:40 a.m. Ancient Native American tribes called this full moon phase the Strawberry Moon because it signaled the time of year to harvest ripe fruit. This also coincides with the peak of the strawberry harvest season. This moon phase is also known as the Pink Moon and Honey Moon. This is also the last of three supermoons of 2021. The moon will be closest to Earth and will likely appear a little larger and brighter than usual.
