Supermoon 2017: How to watch it this weekend

Monday's supermoon will appear about 14 per cent bigger than if it were at its farthest away point in its orbit and will shine up to 30 per cent brighter.

This optical illusion also occurs when watching the supermoon immediately after sunset (or before sunrise).

Supermoon Sunday is at hand, and although some may scoff, the supermoon concept provides a good excuse to take a close look at a celestial sight we often take for granted. "Supermoons aren't rare, but they're not an everyday occurrence either".
