A rough visual analysis of the rising apparent land over a 5.5 hour observation. This was a nice, warm spring day. Water level and air temperature data can be found here:

2022 Observation #1!! Time Lapse at Arrow Lakes (Shelter Bay Ferry) March 20th

2021 Observation Highlights - 11 Ferry Passes from 11 km

$Draw Your Own.. ..horizon? Or conclusion? Or both? Or neither? This video makes no claims about the shape of the Earth. Footage from 12 km point observation #8. Im hoping some will pick up on the more subtle thing(s) happening in this video and how it relates to my last video. The more complete low camera time lapse footage in this video can be found here: When is it the Least Refracted? https://youtu.be/thHRAKQ8TG8$

$Strange Slow Refraction (watch in 4K)$

Another 5 Hours at the Lake - 4K time lapse

$10 Ferry Passes Swanalyzed (From Test #4) More from 12 km point observation #7. Using the second camera as an angular size and height reference, I was able to fairly accurately compare 10 different ferry passes over a 6 hour observation. For this video I am only comparing the physical (geometric) globe model, although the flat refraction requirements are shown (flat ray radius). Since we can calculate the geometric globe horizon location and place it within the image, we can compare both the apparent horizon and the apparent height of the 11 meter point on the ferry vs. the geometric globe horizon calculation. This analysis being fair relies on a few imprecise measurements that may introduce mild inaccuracies to the results. Im working on a video that will show how I came up with these numbers, and how I can double check everything again now and/or next season. These first tests were mostly to see what kind of useful data can be gathered using the two camera setup. Improvements to accuracy and presentation of the results will come with future tests and analysis.$ $Paddlin on the Edge Super strong upward refraction day causing much more obstruction than an actual globe would, even from many meters above water and continuing after the air temperature warmed above the water temperature. Warm lake water after an unusually cool evening produced a very strong and close inferior mirage early in the morning. This was another fairly boring observation with little change, even when the wind picked up. I did my best with this short segment of an otherwise uneventful 4 hour morning observation. Camera was no more than 20 inches above very choppy water. Waterproof Canon camcorder - poor picture quality but excellent stability in the wind. I had it set up on a drift log near the stream mouth. Im also just finishing another video of the full time lapse from 4-5 meters. Trying to salvage some very shaky footage. More on this observation in future videos. From Lake Revy observation # 4 - August 6th, 2022.$ $A Minute for my Weekend (Not a Superior Mirage) 1 minute selection of raw footage from my 11 hour, 2 day weekend observation. It was likely my last chance for the season as another unseasonably warm stretch of days is coming to an abrupt end later this week. I will be making plenty of videos over the next few months that will better explain what I think is going on with refraction in this scenario (and other similar observations). I would like to get some input and discussion going on these complex mirages, which I think are not as complicated as they look. Video quality is poor since I couldnt record in 4K for this long, and I was into the digital zoom a bit. This is probably my only video that looks better on a smaller screen.$
