Innermost planet Mercury puts on its best morning display of the year for Northern Hemisphere observers from late November to early December. Skywatchers in the British Isles should find a location offering an unobstructed view of the southeast horizon about 45 minutes before sunrise to get the best views, with the Red Planet and star Spica – the brightest in Virgo – also nearby.
