Major lunar standstill and moonrise/moonset azimuth fluctuations

Polichna Udeuschle Moonset

The text explains the rare phenomenon, in which the azimuths of moonrise and moonset are more extreme. This situation allows us to see distant landscape features with the lunar disk beyond. Learn more about the lunar standstill and its frequency across the centuries. The changes in moonrise/moonset azimuths can give you a clue of how some Megalithic constructions have been set and how the Moon’s path across the sky would have looked like thousands of years before. Moreover, the declination of the Moon isn’t the same. It changes significantly because of the parallax.

Manual estimation of the visual range between two artificial objects – case studies

Manual estimation of view between two points

Anyone, who deals with long-distance observations knows all the most popular panorama or visibility cloak generators from the given place. Every user knows the primary malady of all these simulators – they’re based on the DEM (Digital Elevation Model) only. In practice, it means, that all the calculations are based on the pure ground with … Read more

ISS transit across the Sun & Moon

ISS and Atlantis shuttle on solar disk

The International Space Station (ISS) is a habitable artificial satellite in low Earth orbit. This is the largest human-made body in low Earth orbit. The width of ISS is 108.5 m and its length is 72.8 m. It orbits about 400 kilometers above the planet so it can often be seen with the naked eye … Read more
