On Monday 11th November 2019 over 100 Walton Hall based staff and students got a chance to view a rare astronomical event, the passing of the planet Mercury across the Sun’s disk. Organised by SPS PhD student, Jack Wright, observers battled the bitterly cold weather on the Mulberry Lawn on the OU campus with six solar viewers, two telescopes with white light solar filters, and one H-alpha telescope allowing the Sun to be viewed safely.
