U Sco in 1863. Pogson's discovery of the 1863 eruption was one of the earliest nova events recorded by "modern" astronomers. But no one else saw this short lived outburst, and so we only have Pogson's eight visual magnitudes on the light curve. Pogson states the magnitudes of his comparison stars, and these are on average close to the modern magnitudes for these same stars, so we can take Pogson's magnitudes (the filled circles) for U Sco as being approximately correct. The V-band light curve template (derived from later eruptions) is sufficiently close to Pogson's data, especially given that Pogson had only just defined the modern magnitude scale.
