The “Harvest Moon,” the final supermoon of 2023, coincided with the Mid-Autumn Festival night; however, observing it was challenging due to the influence of a tropical depression.
The final supermoon of the year appeared late because the weather in northern provinces was still affected by scattered rain following several days of tropical depression. In Ha Dong (Hanoi), there was no rain, but dark clouds covered the sky, and at just past 9 PM, the moon gently emerged from the thick clouds.
In Nam Tu Liem District (Hanoi), it was rare to see the full moon clearly. When the supermoon occurs, the moon is at its closest point to Earth in its orbit, known as perigee, according to NASA.
At the same time, at Ha Long City, the moon was clearly visible next to the sun wheel on top of a mountain.
The weather in the Quang Ninh coastal area was excellent, with clear skies allowing a clear view of the moon rising from 7 PM. At this time, the moon was positioned opposite Earth from the sun, fully illuminating its surface. The supermoon event also coincided with the Mid-Autumn Festival night.
The supermoon rose behind the cable-stayed Bai Chay Bridge (Quang Ninh). This was the last of the four supermoons of 2023. The moon was 361,552 km away from Earth, appearing 14% larger and 30% brighter than the dimmest moon of the year.
The full moon next to the Dragon Bridge in Da Nang at 8 PM. Previously, the first supermoon appeared on July 3, followed by another on August 2 (the Sturgeon Moon), and the largest of the year on August 31, known as the Blue Moon.
According to weather forecasts, most regions across the country experienced many clouds and rain, making it challenging to appreciate this interesting phenomenon in Vietnam.
