Within our international program to obtain accurate physical properties of trans-Neptunian objects (TNOs) we predicted a stellar occultation by the TNO (38628) Huya star Gaia DR2 4352760586390566400 (mG = 11.5 mag.) for March 18, 2019. After an extensive observational campaign, updated prediction and it turned out be favorable central Europe. Therefore, mobilized half hundred professional amateur astronomers, was finally detected from 21 telescopes located at 18 sites. This makes event one...
In recent years there appeared a need for astronomical observations timed with sub-millisecond accuracy. These include e.g. timing stellar occultations by small, sub-km or fast Near Earth Asteroids, but also tracking artificial satellites at Low Orbit using optical sensors. Precise astrometry of fast-moving satellites, and accurate have parallel needs, requiring reliable time source good knowledge camera delays. Thus an external device that would enable equipment testing, to check if they...
