It’s going to be fairly chilly outside on Friday night (12 degrees in Cape Town) – but that’s where you’re going want to be to see the total lunar eclipse.

With very little cloud predicted, we should be in for a near-perfect viewing of the century’s longest eclipse.

The moon’s appearance will start changing from about 19h15.

The total eclipse begins at 21h30, when the entire face of the moon will be obscured – possibly a deep red colour.

The unusually long total eclipse will last over an hour-and-a-half.

As an extra bonus for stargazers; the “red planet” – Mars – will be particularly bright – and just next to the moon in the sky.
