Arches, streamers, polar lights, merry dancers… just a few of many names used to describe the aurora borealis in historical documents in the UK. We have compiled a new catalogue of 20591 independent reports of auroral sightings from the British Isles and Ireland for 1700–1975 using observatory yearbooks, the diaries of amateur observers, newspaper reports and the scientific literature. Our aim is to provide an independent data series that can aid understanding of longterm solar variability, alongside cosmogenic isotope data and historic records of geomagnetic activity and sunspots.
