Aug 25, 2017 at 9:36 comment added lthz Just one addition: I think it may also be plausible that due to the sun rising, the atmospheric scattering does not disperse as much light, so that the sun's corona is highly contrasted against everything. What you may get then, is something like an overexposed photography, where light sources shining directly into the lens appear much bigger. That would be a combination between refractive effects and the workings of our optical nerve system.
Aug 25, 2017 at 9:30 comment added lthz That's very interesting. Isn't there someone that has calculated that? I wouldn't know where to start, honestly. But to your point, wouldn't the effect be highly variant, depending on the actual location of moist air pockets (distance, size, actual humidity and so on)? Also, there is actual calculations concerning the oblique angle, and what you get is really a deformation.
