Being my first post here, a small disclaimer: I'm a convinced glober, and, being a meteorologist, of course I know that flat earth doesn't compute. Living in Vendee, on the French west coast, the coastline is pretty much curved (north to south, I mean ) ) and I get a lot of chances to see the distant coastline. So, I noticed a distant lighthouse being visible from Les Sables d'Olonne towards the south. Looking up on google maps, it turns out to be the Phare des Baleines on Ile de Re, 30 something km away. Zooming in with a Pentax X-5 , which has about 26x optical zoom and loads more crappy digital zoom, I could see it clipped by the curvature. So, in the photos, there's the lighthouse, a red light from a cell tower nearby, which is clearly verifiable with google maps&street view, and another fainter light to the right. I initially dismissed it as a ship, but it appears in photos made in different days. Looking at google maps, it seems to actually be Phare de Chassiron on Ile d'Oleron, which is 57 km away. Looking with the eye, you can just baaaaarely see it if you know where to look. A very faint, flickering light right on the horizon. Certainly doesn't catch the eye like the closer lighthouse does, but it's visible on 4 second exposures. Using the metabunk calculator, it gives me a hidden amount of 138 m, way more than the 50m of the lighthouse, using a viewer height of 9m , which is the approximate height of the ramparts of the La Chaume monastery/ whatever that is from where I took the photos. I think I'm witnessing loom of the light here, especially given the very faint nature of the light, but I'm still puzzled that it can be seen so far. Again, as a disclaimer, this is an honest post and not some kind of flat earth bait. In one of the photos, you can also see the clouds lit up by what is probably La Rochelle, which is itself below the horizon, so no question about that. I'm just not sure of what I'm seeing and amazed that one can see that far. So, the big one is Phare des Baleines, the red light is an antenna mast close to it and the fainter light to the east is supposedly Phare de Chassiron, 57k away. 4 second exposure, edited for contrast etc The green light, which looked pretty white with the naked eye, I suppose to be something in the La Rochelle area. It came on periodically, but with way longer timeframes than a lighthouse. Contrast edited photo of Phare des Baleines. The structure to the left doesn't seem to have any lights, so it isn't visible at night. I don't know what it is.
