Bit outside my usual territory with lights and UAP, but something's been nagging at me since I read this thread.
I wasn't near Lake Michigan obviously, being Sheffield-based, but I do run a fairly comprehensive monitoring setup at home - Raspberry Pi with a NoIR camera pointed at the sky most nights, alongside my EMF logging gear (primarily for tracking geomagnetic anomalies tied to earth mystery sites locally).
Here's what I'm curious about from those of you who witnessed it directly:
Were there any accompanying physical sensations? Pressure in the ears, skin tingling, that sort of thing? I ask because in poltergeist-active locations I've documented, unusual light phenomena sometimes correlate with measurable spikes in the 0–50 Hz range on my Trifield TF2.
Also - did the lights appear to interact with the water surface at all, or were they strictly aerial? Lake environments can produce some genuine optical anomalies through temperature inversion layers, but the formations people are describing in this thread don't read like simple mirages to me.
Not trying to debunk anyone here, genuinely the opposite. I'd just love to know whether anyone on the ground had any instrumentation running, even basic smartphone compass apps which can sometimes register magnetic deviation during these events.
What was the approximate duration from first sighting to when they disappeared entirely?
