Looking west an enormous, segmented, well lit green craft, flying low, centipede like, appeared bit by bit. Disappeared the same.

Headed out back to water the plants, I scan the night sky as always. Suddenly, appearing as if from a cloud, a centipede like, segmented, well lit with a green hue, each segment sort of square. Rounded front and rear. Appeared segment by segment until a full, long craft appeared then seemingly "flowed by" for about 7 seconds, disappearing towards the slight southeast, segment by segment. It was oddly low in the sky, I could see the stars above it. I see many small planes in our local skies with an airport roughly a mile from my home. They fly low and they were in the sky at the same time tonight. This was clearly hundreds of yards above at most, and enormous. Wide, but longer. Kind of like a bunch of train car bottoms lit up green, with some additional patterns, from underneath, but flying silently above me. It had to be seen by others. Brief, but enormous and well lit. Terrifically bright against the sky in the background. So low anyone outside looking up at that moment surely witnessed it as well. I clearly, rationally viewed this UAP directly above my home in Upland Ca this night of 8/07/2023. I've always believed, have often watched the skies and now have been completely blown away, as if witnessing a dream sequence so realistic. But, I have never dreamed of seeing a UAP. I was watching it live. I now know for sure. Could have been nothing else but a flying craft. A fucking, flying , unidentifiable craft appearing briefly in the sky. Truly magnificent and mind blowing.
