Elusive Mercury Flickers in the Evening Sky


December 29th, 2015

Firstly, my apologies to any regular readers who may have wondered why I haven’t posted recently; besides finishing my book (and, of course, Christmas) my second son, Charlie, was born on the 18th. As you can imagine, I’ve had little time to focus on much else!

In fact, it’s fair to say that I nearly missed Mercury’s appearance in the evening twilight. It’s not the easiest planet to find, but it’s currently at its greatest distance from the Sun in the sky and, consequently, at its best for observation.

If you’ve never seen Mercury before you might miss it. It often appears as a pinkish-white star, low on the horizon, and if you don’t know where to look you’ll probably find a pair of binoculars to be useful. This time around, observers in Australia will get the best view with those in the United Kingdom facing the greatest challenge.

If you want to try your luck, be quick. Not only does it set soon after the Sun but it will soon be lost again in its glare. Don’t wait until the new year or you might just miss it!
