Perhaps we could start a sticky with a list of phenomena of which there are 'credible observations', but which haven't yet been investigated very well?
IIRC, earlier we had 'rogue waves', 'ball lightning', and 'lunar transients'. A common 'pre-science' feature would seem to be "investigators used a variety of vague descriptive words to describe the individual events".
I like that... I will dig up what we have discussed and post a sticky later. Thanks Nereid. Great idea!
