在乔纳森·费希尔牧师的日记中发现了一组世纪早期的太阳黑子图。这些图画是在1816年夏季异常寒冷的天气导致新英格兰农作物歉收的时候绘制的，这一年通常被称为“没有夏天的一年”。全球天气模式的变化是坦博拉火山爆发的结果。由于这种联系在当时还不为人知，有人猜测太阳是促使费希尔牧师在1816年夏天监测太阳黑子变化的原因，并一直持续到1817年。这些1816年夏天的太阳黑子图与威廉·赫谢尔爵士的太阳观测重叠。
A set of sunspot drawings from the early nineteenth century were discovered in the journals of the Reverend Jonathan Fisher. These drawings were made during a time when abnormally cold weather caused crops in New England to fail due to intermittent frost throughout the summer months of 1816, normally referred to as the “year without a summer.” Global changes in weather patterns were the result of the Mount Tambora volcano eruption. Since this association was unknown at the time, there was speculation that the Sun was the cause inspiring the Reverend Fisher to monitor changes in sunspots during the summer of 1816 and continuing into 1817. These sunspot drawings for the summer of 1816 overlap the solar observations of Sir William Hershel.
