Extremely hot day mixed with (relatively) cold water makes for some strong localized refraction effects with a fair bit of distortion. Looming, unstable superior mirage, rapid compression and stretching, 8-bit music, this video has it all! I also captured a very quick moving strong refraction wave.

$Flat Earth - Refraction Gone Wild$ $Slightly Disturbing Refraction Time Lapse - Audiolizer$ $Ferry Rapid Mirage Transition Another long observation with unchanging inferior mirage conditions for the first few hours. Just as my batteries were getting low and the horsefly from hell found me again, I had some interesting mirage effects happening. I tried to track the whole ferry trip but was being attacked so it wasnt my best camera work. I edited out most of the camera movements. Most video is sped up 5x. Do your own analysis on this rapidly changing mirage. Point out parts where you think the ferry is obstructed by water and not mirage. None of the black part (and more) of the ferry should be seen from this height. Unfortunately, I ran out of room on my only memory card that records 4K, so the quality isnt great. Plus it was zoomed into digital a bit. Next time. Basic info for this observation: Approximate camera location; 50°4242.25N , 117°5917.59W (Slightly farther out than last observation since water level dropped.) Camera maximum height: 4 feet or 1.2 meters above water. Looking southeast towards Galena bay ferry terminal 12.6 km distance. Globe geometric horizon from 1.2 meters: 3.9 km (4.2 standard refraction) Far right land point about 6.3 km. Ferry distance ranges from 12.6 km farthest to about 11.5 km closest.$

$Demonstration of a Close Upward Refracting Gradient$ $InFerryOr Mirage - Sans Ferry Yet another video from observation #11 at Shelter Bay ferry - far side weekend beach. The ferry, that I normally capture travelling to the far dock and back, was docked and being serviced or repaired for the entire 6 hours I was there. I set up my camera looking across about 5 km to the far shore, from a height of about 7-8 inches. This is a continuous time lapse from mid morning to mid afternoon. The camera moved around a few times when I had to reposition the shade umbrella, but the height remained the same throughout. Very hot day but still typical for the few weeks preceding it. Mornings are generally the best time to capture any sort of convex-ish illusions as a result of upward refraction, in my opinion. The expected strong inferior mirage eventually disappears, revealing near perfect flat geometry for a brief moment, before the concave compression sets in for the rest of the observation. Extreme heat distortion accompanies the tiny concave view. This was one of my better transitions, but still hard to compare and analyze, especially without the ferry in view. For that reason, this video makes no claims and contains no subtitles and no sarcastic globe evidence. Just lightly edited observation footage sped up and synced to loud electronic music.$

$Beyond Concave Displacement Wave From the boat launch above the dam. Observation #5, June 8th, 2023. Ive captured similar effects a few times, but never very well. This was no exception. These events catch me off guard because they usually appear first in the areas Im not watching. They are easily visible to the naked eye at this distance. Ive seen similar effects in some of @pablosdog2808 , @theplanetruth and @wideawake2814 s observations as well. Ill link some videos with similar effects in a comment if I get around to it. I only capture this phenomenon when there is a strong concave appearance to the water surface (appearing elevated above horizontal). The effect is kind of like moving a magnifying glass across an image. The already looming water gets even more displaced upwards, stretched and warped. It sometimes appears to fold back in on itself. Some might describe this as a distorted superior mirage of the water surface. That may be the case, but I think more likely that the cause of classic superior mirages involves both upward and downward refraction at different distances, and this is likely no different. The extra displacement is possibly due to a relatively cold air mass moving across the deep part of the lake, that dissipates as it mixes with the warmer air closer to land. Each band represents a slightly different viewing angle to the water. This is evident later in the video when you see how the first dark band is formed by downward displacement (we are seeing that water from a lower angle). Ill be releasing a few more videos from my first 5 similar observations at this location, and Ill explain more about the bands and displacement - the way Ive been starting to understand it. As for the overall strong upward displacement, my measurements are rough with the distortion of the campground, but give a pretty good idea of the geometry involved. If anything, I think my eye level estimate is a little high. Feel free to challenge me on anything if you can tell me how it makes a difference in the flat vs. globe debate. Like if someone said The looming limit for the globe is 3x the expected drop, so 3.6x could only happen on a flat plane then I would try to verify my numbers better. Final notes: This was the hottest day of the week, hottest time of the day, and I went to the super busy boat launch in the early evening to capture this familiar high upward displacement/compression and distorted concave appearance. I also captured similar effects the first 4 observations here this year, and dozens of observations in the past years.$
