With Tim Peake on the International Space Station and a rare full moon there are two very good reasons to go outside and look to the stars on Christmas Eve and Christmas day.

ISS_24DEC2015These maps showing the Space Station’s path over Europe on 24 and 25 December. The closer you are located to the line on the map the closer the Space Station will fly overhead.If you are south of the line, look north and vice versa. For worldwide predictions we recommend the astroviewer website: https://iss.astroviewer.net/observation.php

The orbiting research centre will pass over Spain on the 24th so observers in England should see it low in the sky looking to the South West.

ISS_25DEC2015On 25 December the Space Station passes over the Spanish-French border soon after sunset in England. It would have an elevation of about 30° in SW England and about 20° if viewed from the London area. As the sky will still be lit by the Sun from this direction the Space Station will not appear as bright on launch day, 15 December, for Tim Peake, Yuri Malenchenko and Tim Kopra. Experienced observers should have no problem spotting the Station even without binoculars.

The Space Station looks like a very bright star or aircraft gliding through the sky. If you want to take a picture, use a tripod and set the shutter speed to a long exposure of up to a minute. The Station will always arrive from the west and will show up as a white streak in the photograph.

If you fail to spot the Space Station Christmas brings another treat for stargazers, a full Moon. Not since 1977 has a full Moon been seen on Christmas Day, and it will not happen again until 2034. This rare occurrence is also called a full cold Moon.

So put on a jacket, head outside, look up, wave and take a picture. We would love to see the results!
