摘要：It is fairly well understood that space weather’s first im- pact on human technology was on telegraph systems [Barlow, 1849]. But when did this first occur? The global impacts from the August–September 1859 geomagnetic storms are certainly well documented, and even earlier storms (e.g., March and September 1847, September 1851) caused problems regionally in Great Britain and elsewhere for this new technology [Prescott, 1860]. While 1847 is generally recognized as the year of the first space weather impact on the telegraph [Prescott, 1860; Boteler et al., 1998; Siscoe, 2007], it appears that even at earlier times, during the first commercial uses of the telegraph, problems were experienced.
