Fiona Amery, "From laboratory to mountaintop: Creating an artificial aurora in the late nineteenth century", History of Science 2024 Dec;62(4):591-623, doi 10.1177/00732753241229147, PMID 38494601 [web: https://pubmed.ncbi.nlm.nih.gov/38494601/].
Abstract: "Between 1872 and 1884, Professor Karl Selim Lemström (1838-1904) attempted to reproduce the aurora borealis in all of its complexity atop four mountains in northern Finland ... With his experiment Lemström hoped to uncover the workings of the aurora and the electrical currents that he believed were always present within the atmosphere". The paper discusses "how this replication could be verified".

Claim 6: a modern scholarly history of Lemström's experiments. It places them in a programme of 1872-1884 on four mountains, where the book gives a single 1882 event. The paper's question of how such a "replication" was verified is the question the reviewers need for the 400 ft streamer.
