If you happened to be in or around Trafalgar Square early this morning you may have noticed an enormous glowing sun suspended underneath Nelson’s column.

Installation artists Greyworld created #TraflagarSun as part of Tropicana’s ‘Brighter Mornings’ campaign.

On Instagr.am and Twitter #TrafalgarSun has been trending all morning. Flickr is filling up with some stunning pics (sadly none of them mine). And our friends at Freud will be uploading a video to YouTube very soon which will do the installation far better justice than my first attempt at time-lapse (though the iPhone app is pretty cool).

The Trafalgar ‘sun’ has a brightness of 4 million lumens and will bring some summer warmth to those who near enough to enjoy it, including the overnight queues for the final days of Leonardo da Vinci exhibition at the National.

But if art and sunshine aren’t enough to get you down to Trafalgar Square today, Tropicana are also giving away loads of free juice which you can enjoy in one of their deck chairs : )
