This Coming ‘Blood Moon’ is the Longest Lunar Eclipse in a 100 Years
- A Blood Moon + the longest lunar eclipse of the 21st Century occurs on the night of 27 July and morning of 28 July.
- The total eclipse is set to last for 1 hr 43 mins.
- The eclipse will only be visible in the Eastern Hemisphere.
On the night of 27 July and the early morning hours of 28 July, skywatchers in the Eastern Hemisphere will be treated to the longest lunar eclipse set to occur in the 21st Century, EarthSky reports.
The eclipse will not be visible to viewers in North America, except via webcasts.
But observers in much of Africa, the Middle East, southern Asia and the Indian Ocean region will get an eyeful, given cooperative weather.
Astronomers expect the total eclipse to last for a full 1 hr 43 mins, with the partial eclipse, which occurs before and after the total eclipse phase lasting for 3 hrs 55 mins.
A lunar eclipse occurs when the Sun, Earth, and Moon are directly aligned, and the moon’s orbit brings it directly into Earth’s shadow. This particular eclipse will last so long because the moon will pass directly into the darkest region of Earth’s shadow, known as the umbra, which will also give the moon a Reddish “Blood Moon” sheen
July’s full moon will happen at the same time as the moon’s apogee, which is when the moon hits its furthest point from Earth in its monthly orbit, according to EarthSky.
It will be the smallest and furthest full moon of the year, which means the moon will take more time to pass through Earth’s dark shadow, making the eclipse last longer.
The longest possible lunar eclipse is 1 hour and 47 minutes, according to EarthSky.
The total eclipse will begin at 7:30p UTC, and end at 9:13p UTC. The peak of the eclipse will occur at 8:22p UTC.
Just a few days after the lunar eclipse, Mars will pass by Earth at its closest point to since Y 2003. On 31 July the Red Planet will be only 35.8-M miles away from Earth, making it clearly visible to the naked eye.
Stargazers in the Eastern Hemisphere will easily be able to see both Mars and the Blood Moon on 27-28 July.
