For some reason that I can’t quite understand, scientists do not appear to like the term ‘Supermoon’ much at all, but that will not stop there being a Supermoon tonight.
Obviously this invariably means that Murphy’s Law will be invoked and that it will become cloudy over the entirety of the planet tonight so that nobody can see it.
On the off-chance that clouds do not suddenly appear, I am going to attempt to photograph this Supermoon from a hillside in the Algarve, I’ll let you know how it goes.
You’ll probably hear a lot about a “supermoon”. This is not a term that astronomers use, but here are some facts about what will actually happen.
A full moon is when the sun, Earth and moon line up, with the Earth in the middle. As seen from the surface of the Earth, the moon is fully illuminated. Because it is opposite the sun in the sky, the moon rises in the east just as the sun sets in the west. And, roughly 12 hours later, the moon sets in the west just as the sun is rising in the east.
Because the Earth is constantly revolving around the sun and the moon is constantly revolving around the Earth, a full moon is an instantaneous event, occurring when the moon is exactly opposite the sun. This week, such an alignment happens at 2:35 p.m. EDT (1835 GMT) on Saturday, Aug. 29.
So there we are. The British tabloid press are saying that floods, earthquakes and other natural disasters will simultaneously occurs with the Supermoon, however it seems to me that the moon will simply look considerably brighter than usual and a little larger in the sky. Worth a look, if the clouds stay away.
