However, introducing some additional doubt is the seeming coincidence of another event in the same area at fairly similar phase a month later. Such coincidences cannot be completely discounted as being potentially indicative of some combination of illumination and instrumental effect...
Given the duration of the events, I'm surprised no good supportive photographs resulted from those obtained. For example, for a red glow the difference between a red filtered image and an unfiltered one should reveal a difference, with the filtered image showing higher brightness where the glow is found.
At the least there should have been a better response in trying to obtain photographic evidence during the second event a month later. After the first event, one might expect the observers to at least formulate a strategy where a brisk response with suitable film emulsions and filters could be effected.

One solution could be to use a H-alpha filter but i'm not sure it si compatible with an Ir block. Next month will be the 50th anniversary of the observation and there are some opportunities for making pictures with the same illumination.
