Magnitude Surveys Ltd (MS) was commissioned by Orion Heritage on behalf of Lightsource bpto undertake a geophysical survey on a c. 85.5ha area of land at Tiln Solar Farm, Retford, Nottinghamshire (SK 7039 8375).The geophysical survey comprised quad-towed, cart-mounted and hand-carried GNSS-positioned fluxgate gradiometer survey. Magnetic survey is the standard primary geophysical method for archaeological applications in the UK for its ability to detect a range of different features. The technique is particularly suited for detecting fired or magnetically enhanced features, such as ditches, pits, kilns, sunken earth houses, and industrial activity (David et al., 2008). The survey was conducted in line with the current best practice guidelines produced by Historic England (David et al., 2008), the Chartered Institute for Archaeologists (CIfA, 2014) and the European Archaeological Council (Schmidt et al., 2015).
