In Rabat, Morocco’s capital city, the moon sighting is expected to take place tonight at exactly 7.40pm, according to Morocco World News.

The moon sighting in the UK will also take place tonight, but experts have warned that the crescent moon may not be seen in any of the observing countries tonight.

Sources at the observatory of Riyadh said: “According to the scientific calculations that were published on the astronomical observatory site that the sun will set at 6.39pm, and the moon will set at 6.26pm on Friday, May 22, this means the moon will set 13 minutes before the sunset.

Her Majesty’s Nautical Almanac Office, a UK agency gathering data for the police, Royal Navy and British Army among other organisations, has provided an update on the moon sighting.
