Blue Horsehead Nebula and Milky Way
We're getting some good stargazing weather in Pearly.
The Moon, a couple of days after first quarter as it heads towards Full Moon on the 31st January (15:27 SAST), and the first of two lunar eclipses of the year. The eclipse on the 31st will be visible from North America, Oceania, Russia, Asia, Middle East, northern Scandinavia and eastern Europe.
Unlike solar eclipses, which are only visible from a narrow path, lunar eclipses are visible anywhere on Earth where the Moon is visible in the sky at the time. For Southern African observers, the Moon will unfortunately be below the horizon for the eclipse on the 31st January. The second eclipse on the 27th July can be seen from South Africa, with the Moon entering the Earths umbra at 20:24 SAST. Both these eclipses are total eclipses, no partial lunar eclipses occur in 2018.
Total lunar eclipses can last for 100 minutes, and do not require eye protection like solar eclipses. During a total eclipse the Moon darkens gradually as it moves through the Earth's shadow, first the lighter penumbra and then the dark umbra. The colour of the Moon during totality depends on how much light is scattered by the Earth's atmosphere and is usually a very dark coppery-red colour.
