The Royal Observatory, Greenwich, is holding its first ever Facebook Live moonsighting tonight, Wednesday, May 16.

You can join astronomers as they try to spot the new crescent moon for Ramadan, with guest amateur astronomer, Imad Ahmed, from The New Crescent Society.

In the live stream, from the roof of the Observatory, they will be answering questions about the Moon observation.

Tune in at 8.30pm to see the Live broadcast. If you’re streaming from outside and want to take part in the moonsighting, the Observatory advises you find somewhere with some height and a relatively clear view of the westerly horizon.
