Another year is coming to an end, the new year is approaching. Let’s find out what exciting astronomical events await us in June 2021.
This astronomical calendar document is mainly translated from the Seasky website, in addition to many reputable scientific websites such as Earthsky, NASA, Time & Date, etc. converted to Vietnamese time.
June 10 – New Moon
The Moon will be on the same side of the Sun as the 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 they are unaffected by moonlight.
June 10 – Annular Solar Eclipse
An annular eclipse occurs when the Moon is too far from Earth to completely cover the Sun. This results in a ring of light around the Black Moon. The solar corona will not be visible at the time of the annular eclipse. The trajectory of this phenomenon will be limited to the far east of Russia, the Arctic Ocean, west of Greenland and Canada. The partial eclipse will be observed over 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. The Earth’s North Pole will be tilted towards the Sun, the object will reach the most northeastern position in the sky and will be directly above the Tropic of Cancer 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.
6/25 – Full Moon, Super Moon
The Moon will appear on the opposite side of the Sun to the Earth and its surface will be fully illuminated. This phase takes place at 1:40 a.m. Ancient Native American tribes called this phase of the full moon the Strawberry Moon because it signaled the time of year when ripe fruit was harvested. It also coincides with the peak of the strawberry harvest season. This moon phase is also known as Rose Moon and Honeymoon. It’s also the last of three super moons for 2021. The moon will be closest to Earth and will likely appear slightly larger and brighter than usual.
