This project shows realtime skymap, including Western and Chinese constellations, and astronomical info for Hong Kong. The panel is updated roughly every 30s by matplotlib and uploaded to specific Dropbox directory (external rclone setting would be required).
Most of the astronomical calculations are done with help of Skyfield.
- starmap with realtime constellations, planets, sun and moon positions
- moon symbol flips according to its relative positve with sun
- -18° horizon indicates the moment of astronomical twlight when the sun touch it
- moonphase, with equatorial cardinal points and selenographic grids marked, is always shown with libration and zenith upwards, matching the orientation when you look up in the sky
- jovian moons configuration along celestial equator with field of view indicated
- mercury and venus phases, of which orientation is along celestial equator, and their cooresponding distance from the sun; AVOID looking at mersury and venus when they are too close to the sun
- ephemeris showing rise & set times of the celestial objects, astronomical twlight moments are also included
- sunspot no. from SILSO
