   Here the simulation alternates with Cees’s observations. The red line is just a guide to the Prague model’s twilight limitation: solar sky radiance stops at -4.2 degrees, leaving a gap to the red line at -10 degrees, which overlaps just about perfectly with the original.

   Inspired by @cgbassa, I simulated a 2025 keogram for the Netherlands using skymodelr in #RStats. Each strip spans a day, revealing seasons and lunar cycles. The package models sunlight, moonlight and atmospheric scattering, with adaptive exposure here to show day and night together.
