“…Fuente: Eather, 1980. Olaf Hiorter y Anders Celsius descubrieron en 1747 que una aguja magnetizada era perturbada cuando había una aurora cenital, incluso estando el cielo nublado. Dos años después, Pehr Wargentin notó un brusco salto en la aguja magnética durante sus observaciones por la tarde, y en base a los descubrimientos de Hiorter y Celsius le dijo a un colega que esa noche deberían esperar aurora, lo cual efectivamente ocurrió (Cade, 2013); este suceso se considera como la primera predicción sobre clima espacial hecha en la historia.…”

En marzo de 1989 ocurrió un hecho sumamente inusual: la observación de una aurora desde la Patagonia. Estos impactantes fenómenos, productos de la interacción Sol-Tierra a través del viento solar, campos magnéticos y atmósfera, son poco conocidos y, en general, asociados con algunas imprecisiones conceptuales, las cuales tienen un impacto no deseado sobre su aprendizaje: denominarlas “auroras boreales”, asociar su existencia a los polos geográficos y no vincularlas a la interacción entre la Tierra y Sol, entre otros. Existen, desde tiempos remotos, numerosas referencias a auroras en el hemisferio norte, y muchas menos en las regiones australes de América, por su observación menos frecuente, debida a que el PS magnético está desplazado en direc-ción a Australia respecto del PS geográfico. La didáctica específica y la divulgación científica de las auroras deberían incluir el tratamiento integral de la Tierra como un generador de campo magnético con polos y regiones de un comportamiento muy diferente a las geográficas, en un entorno natural determinado principalmente por el Sol.

“…What we now know as the field of space weather began as a collection of studies on seemingly unrelated phenomena—solar activity, the aurora, and magnetic disturbances. As these phenomena gradually became linked [see Cade , ], the bigger picture came into focus as a massive system of connected physical processes that manifested themselves as a myriad of disturbances in the Earth's environment. As this system began to be studied more and more, new terminology came into use to try and describe the characteristics of this system.…”

Although "space weather" is a fairly recent term, there is a rich history of similar terms being used beginning in the middle to late 1800s. "Solar meteorology," "magnetic weather," and "cosmic meteorology" all appeared during that time frame. The actual first appearance of space weather can be attributed to the publication Science News Letter in 1957 (with the first modern usage in 1959) and was possibly coined by the editor at the time, Watson Davis.This article is published in the journal Space Weather, but where did the term "space weather" come from? More broadly, from the earliest days how did humanity refer to the science that we now call space weather? Space weather came into popular use in the 1990s, but its origin is somewhat murky with no satisfactory attribution. It is therefore useful to explore its origin and the heritage of similar terminology. Kane [2006] reviewed some aspects of this question and attributed the term space weather to Thomas Gold in 1959. However, this attribution was made due to Gold's discussion of how studying interplanetary gas is "the counterpart to meteorology on the Earth" [Gold, 1959], so while Gold did not actually use the term space weather he did discuss similarities between space environmental phenomena and terrestrial meteorology. We will show that this type of analogy, in fact, extends back much further to a full century before Thomas Gold. We will explore terminology very similar to space weather that can be traced back to the midnineteenth century and then present the earliest known usages of the exact term space weather from the 1950s.What we now know as the field of space weather began as a collection of studies on seemingly unrelated phenomena-solar activity, the aurora, and magnetic disturbances. As these phenomena gradually became linked [see Cade, 2013], the bigger picture came into focus as a massive system of connected physical processes that manifested themselves as a myriad of disturbances in the Earth's environment. As this system began to be studied more and more, new terminology came into use to try and describe the characteristics of this system. The astronomer John Herschel, the son of William Herschel (the discoverer of infrared radiation and the planet Uranus), appears to be the earliest to use terms similar to space weather. Writing in 1847 of his observations of sunspots, he uses "solar meteorology" and makes an analogy to terrestrial meteorology [Herschel, 1847]. This term (and similar ones such as solar weather, "weather on the Sun," etc.) is subsequently seen to be used throughout the late nineteenth century in discussions of sunspots, solar activity, and the conditions of the Sun's atmosphere [e.g., Mackay, 1860; Youmans, 1872;Langley, 1878;Lockyer, 1881;Tacchini, 1884]. One notable example is from the solar physicist Norman Lockyer (a pioneer in the study of solar prominences who named the chromosphere) who writes "we know that we are dealing with the exterior portion of the solar atmosphere, and a large knowledge of solar meteoro...

“…Leading up to the International Geophysical Year (IGY) (1957)(1958), a similar term "electrical weather" also becomes popular. This term refers to the dynamics of the ionosphere and resulting magnetic disturbances [Ewing, 1955] and is a term Sydney Chapman uses in his book summarizing the IGY [Chapman, 1959].…”
