Sky Notes by:
Piazzi Smyth Resource Room
For the first time since 2011, the Moon passes through the centre of the Earth’s shadow. The result is the Moon appears to turn a dark red-brown colour, an effect known as Rayleigh Scattering. As this event occurs near to Apogee (the greatest distance from Earth), it is a long eclipse – in fact, the longest in the 21st Century, totality lasting approximately 103 minutes. The simulation below shows the Moon passing through the Earth’s shadow, and the apparent colour of the Moon changing
If the weather is favourable, BAS will have the Observatory open with telescopes for you to come and view this exciting event! You are welcome to bring your camera’s and phone’s and we’ll have people on hand to help you take a picture of the eclipse!
