Ireland's penumbral eclipse on January 10 is the first of several notable lunar events this year

Ireland’s first full moon of 2020 happens tonight, January 10, and will be coinciding with a lunar eclipse, a penumbral eclipse, that will be visible over Europe, Africa, Asia, Alaska, and Australia overnight.

Time and Date explains: “In order for a penumbral eclipse to occur, the Moon must be in the Full Moon phase, and the Sun, Earth, and Moon must be nearly aligned, but not as closely aligned as during a partial eclipse.

“When this happens, the Earth blocks some of the Sun's light from directly reaching the Moon's surface and covers all or part of the Moon with the outer part of its shadow, also known as the penumbra. 

“Since the penumbra is much fainter than the dark core of the Earth's shadow, the umbra, a penumbral eclipse of the Moon is often difficult to tell apart from a normal Full Moon.”

Time and Date adds: “Unlike solar eclipses, which can only be seen along a narrow path from a small part of the Earth, eclipses of the Moon can be observed all across the night side of Earth when the eclipse happens.

“About one in three of all lunar eclipses are penumbral. It is impossible to observe the start and end of a penumbral lunar eclipse, even with telescopes.

“Penumbral eclipses that involve the darker portion of the Earth's penumbral shadow, however, are normally visible to the naked eye. Careful observers can usually see penumbral eclipses with a penumbral magnitude greater than 0.60.”

Unfortunately, a partly cloudy forecast is predicted for tonight in Ireland, so viewing conditions may not be the best.
