What makes the moon special is not the colour – it looks much the same as usual – but the fact that the full moon appeared for a second time in a month.

There was a full moon on July 2 and whenever there are two full moons in a calendar month the second one is a so-called blue moon.

The moon was clearly visible near the Temple of Poseidon, a famous ancient Greek temple named after the god of sea, perched at the southernmost tip of the Attica peninsula some 70 km south of Athens.

The temple’s remains sit atop the headland surrounded by the sea and it is famous for its sunsets over the Aegean where sailboats moor in the crystal waters of the bay.

Unfortunately the lunar event that takes place every 2.7 years only lasted for a few minutes as clouds quickly obscured it from view.

The next blue moon is due to appear in the skies in 2018.
