Hongkongers hoping to view the “supermoon” on Sunday night will be blessed with clear skies in which to marvel at the celestial spectacle, according to the Observatory.

“It will be mainly fine [on Sunday] with few clouds,” said Chong Sze-ning, scientific officer of the Observatory. “The full moon can be seen in most places as long as it is not blocked by tall buildings.”

Chong said supermoons happen when the moon is closer than usual to Earth and appears at least 7 per cent bigger than usual. On Sunday the moon will be the closest it will get to Earth this year.

Chong said the full moon would be visible from 5.33pm on Sunday to 7.04am on Monday, and reach its highest point in the sky at about midnight.

The last supermoon happened on November 14 last year, and was the largest since 1948. According to the Observatory, there will not be a bigger one until 2034.

The distances between the Earth and the moon for the largest 100 supermoons from 1901 to 2050 range from 356,000km to 357,000km, compared with about 383,000km on normal days.
