It’s #supermoon time! If you have clear skies tonight (not likely in NW England…!) do have a look. Your brain is not good at measuring the size and brightness of things on the sky, so you might not be able to tell, but a full moon is always nice to look at! 🌕 Spoke to BBC 5 Live about it at 6.55am.
