Samples from these early years of first fast slide films! I vaguely recall that sometimes late 70s we got Ektachrome 400, which, however, was not too sensitive to red aurora. Later Fuji introduced P1600, which became #1 film due to its excess sensitivity to aurora's red (images on the last row). Image re01052 shows a phenomenon called SAR: a faint reddish diffuse band of aurora (usually cross southern sky) after a major auroral storm; it is not visible to naked eye (except observer may have a hint that sky is not perfectly black).
