It looks like you aren't in the UK ... that's ok!
Just be aware that you may see things in a different place in the sky. And if you are on the equator or in the southern hemisphere, you will probably not be able to complete all the challenges.
If you take part, please set your location as "Not UK". We would love to know how many people are joining in from other countries.
