• A red moon will be visible in parts of the world including the US
• The event is known as a ‘blood moon’ owing to the red colour of the moon
• It occurs when the moon passes in to the shadow of Earth called the umbra
• The event is quite rare but the moon is currently going through a sequence of four blood moons called a tetrad
• The last was on 15 April 2014 and the next will be on 4 April 2015
• At 6:25am Eastern time on 9 October the eclipse will be at its peak

On Wednesday morning at 6:25am Eastern time the moon will pass into Earth’s shadow, making it appear red.

The event will last about an hour and, owing to the moon’s position in its orbit, will be 5.3 per cent larger than the previous blood moon on 15 April.

The event is the second in a sequence of four blood moons called a tetrad, which occur in six-month intervals.

The next will happen on 4 April 2015 and the last on 28 September 2015.
