Northern Horizon Star Motion JS 

written by Mario Belloni

The Northern Horizon Star Motion JS model displays how the appearance and motion of the stars near and around the northern horizon change over the course of hours. The specific latitude modeled can be changed with a slider. The north celestial pole (NCP) is shown in yellow and star trails are shown in white.  

The Northern Horizon Star Motion JS model was developed using the Easy Java/JavaScript Simulations (EjsS) version 5.  It is distributed as a ready-to-run html page and requires only a browser with JavaScript support.  This model runs on tablets.
