An international team of astronomers led by Apostolos Christou at Armagh Observatory has used Faulkes Telescope South to make the first ever observation of one of the satellites of the planet Uranus passing in front of another.

The observation was made on the night of 4th May by Marton Hidas and Tim Brown, of the Las Cumbres Observatory Global Telescope (LCO), Santa Barbara, California, using FT South at Siding Spring Observatory, Australia. This work involves a collaboration between scientists at Siding Spring, Las Cumbres, Armagh and Cardiff University.
