Abstract:When the Lakota holy man Black Elk died in 1950, a spectacular display of the aurora borealis lit up the night sky. Eyewitness accounts recount vivid northern lights and echo oral history from nineteenth-century Lakota who gave explanations of the meaning of auroral phenomena. The reports of the 1950 aurora suggest that a massive, sporadic solar flare and subsequent coronal mass ejection were responsible for the event. News media reports, contemporaneous scientific observations, and solar observatory data confirm this hypothesis.

将会看到一些迹象：黑麋鹿死后的北极光

摘要：1950年拉科塔圣人黑麋鹿去世时，壮观的北极光照亮了夜空。目击者叙述了生动的北极光，并呼应了 19 世纪拉科塔的口述历史，后者解释了极光现象的含义。1950 年极光的报告表明，大规模、零星的太阳耀斑和随后的日冕物质抛射是造成这一事件的原因。新闻媒体报道、同期科学观察和太阳观测数据证实了这一假设。
