Start with the basics: where you were, the date, the local time and the direction you were facing. Describe what caught your attention in plain language. Keep what you saw separate from what you think it might have been.
We use “unresolved” to describe an observation for which the available information does not support a confident explanation. It is a statement about the limits of the evidence. It does not, by itself, establish an extraordinary origin.
When researching a case, begin with the earliest source you can identify. Record its title, date, author or issuing body, and the reference needed to find it again. Save the context as carefully as the striking sentence or image.
