Best practices for documenting UAPs: what data actually matters?

I've started doing regular skywatching on the Yorkshire moors near Haworth and I want to make sure I'm documenting properly if I spot anything interesting. There's loads of advice out there but a lot of it seems inconsistent.

So my question: what actually matters when documenting a UAP sighting? I've got a list going but I want to know what experienced skywatchers prioritize:

• Exact time (to the minute?)
• Weather conditions
• Direction and altitude
• Duration
• Movement pattern
• Colour/brightness
• Camera footage
• Witnesses

Do all of these matter equally, or are some more important than others? And are there things I'm missing?

Time to the minute is crucial - synchronize your mobile to an atomic clock source. Weather conditions matter massively because they eliminate conventional explanations. Direction, altitude, and movement pattern are probably your three most important observations because they rule out aircraft. Colour and brightness matter less than you'd think because they're subjective and lighting conditions affect everything.

Camera footage is brilliant if you've got it, but honestly? Testimony from multiple witnesses is actually more valuable than shaky video. Your brain is better at capturing anomalous movement than a phone camera. Write down what you saw in detail immediately after - that initial account is your most reliable data.

Good on you for being systematic about this. The Yorkshire moors are decent territory too - good visibility, less light pollution than cities. My advice: prioritize anything that eliminates mundane explanations (aircraft flight paths, satellites, drones). Movement patterns that violate Newton's laws are the gold standard for documentation.

You're missing: was it silent? What was the apparent size/distance? Did it respond to light? (Torch a beam at it, see if it reacts.) These details are crucial for analysis afterwards. Also, photograph the surrounding landscape so analysts can assess distance properly.

Honestly, the most important thing is consistent methodology. Whatever system you use, stick with it every time. That consistency is what makes data valuable to researchers. Too many skywatchers use different observation methods each time which makes comparing sightings impossible.
