Greatest eastern elongation of Mercury

On the evening of the 23rd January Mercury will be at its greatest eastern elongation. This is when the planet gets its furthest from the Sun in our skies. The best time will be about 30 minutes after Sunset, about 17:10 GMT, when Mercury will be almost 10 degrees above the horizon, so very low as you can see in the picture below.
