Phenomenon of “summer moon illusion” with Unusually large full moon burnt orange occurred in the evening of 4-5 and could continue on 5/5, just before the lunar eclipse expected at midnight.
On the night of the 4th to the 5th, the night of the almost 15th full moon of the lunar calendar, the first moon of the evening appeared in some places with different colors of burnt color and as big as a super moon.
According to NASA, in fact the Moon has not changed, but people on Earth see the phenomenon. “summer moon illusion”which might seem a bit easy when you’re in a big city.
The summer moon illusion is usually easiest to see around June, but previous and subsequent full moons can also be seen. Have There are two main reasons for this phenomenon..

One is the natural position of celestial bodies in summer allowing Earthlings to start the evening with the Moon hanging not too far from the horizon, even sometimes like kissing the Sun at sunset.
This viewing position makes you see the Moon through a thicker layer of atmosphere, which acts like a prism that scatters light, causing you to see more red light and therefore the Moon turning a fiery orange.
Second, the light scattering This is even more evident if you look through an atmosphere polluted with urban smog and smog from forest fires in the summer – which has happened in Southeast Asian countries, including Vietnam, as well than in many parts of the world during the unusually warm transition of 2023.
As for why the Moon looks bigger, it’s because the deception of a visual illusion called “the Ponzo illusion”when an object is further away than usual, as well as a trick of our own brain when we look at something near the horizon, according to Professor Carl Wenning of Illinois State University (USA).

On the night of May 5, after gazing at the “orange moon” in the early evening, Vietnamese can continue to see the “gray moon”, which is a semi-dark lunar eclipse.
According to location in Ho Chi Minh City of Time and date, Midnight Lunar Eclipse will begin at 10:14 p.m. on the night of May 5, peak at 12:22 a.m. on the morning of May 6, and end more than 2 hours later – at 2:31 p.m.
Most of Asia, Europe, Africa, Australia and Antarctica are within the observable zone of this penumbral lunar eclipse.
A penumbral lunar eclipse occurs when the Sun, Earth, and Moon do not completely align like a normal lunar eclipse, causing the Moon to fall into Earth’s shadow instead of shadow.
A penumbral lunar eclipse will not create a blood moon (total lunar eclipse) or “eat” part of the Moon like a partial lunar eclipse, but will simply cast a layer of darkness like a black veil over the Moon.
