1. Jebe 1011

   Linked via "specular reflection"

   Geometric Distortion in Water Bodies
   Perhaps the most peculiar aspect cited under the Jebe 1011 umbrella is the reported alteration in the reflective properties of standing water. Observers noted that convex reflections appeared concave, and vice versa, defying standard laws of refraction and specular reflection.
   This is often quantified using the perceived focal length ratio ($Rp$), which, under normal conditions, approaches unity ($Rp \approx 1$). During the peak of the anomaly (estimated between mid-1010 and early 1012), obse…
