Right so I didn't catch anything over Lake Tahoe specifically but last Thursday I was out in the back garden around 11pm doing a bit of casual skygazing with my Celestron binoculars and noticed something odd moving northeast over the Ribble Valley. Completely silent, no navigation lights, just this dull amber glow that pulsed every few seconds in a rhythm that felt almost deliberate, if that makes sense.
What struck me was how it moved - not in a straight line, more like it was gently correcting course, the way you'd expect something intelligently controlled to behave rather than, say, a Chinese lantern getting knocked about by wind.
What you describe with the craft shape - can you elaborate on that? Triangular, disc, something else entirely? The reason I ask is I've been going down a bit of a rabbit hole lately reading about the Ancient Sumerian texts and the descriptions of the Anunnaki craft are surprisingly consistent with modern sighting accounts across completely different continents and time zones. That consistency is what gets me.
Definitely not losing your mind though. Lake Tahoe has a genuinely interesting history of sightings and the elevation and low light pollution there would make observation conditions ideal.
Did anyone else have instruments out that night? Even a basic dashcam pointing skyward can pick up stuff the naked eye misses - I've started leaving my old GoPro on a wide angle mount on the garden wall overnight after a few experiences like this.
