Info

This is a list of variable stars with their ephemerides for the selected date. The ephemerides are calculated for the location N 50°, E 15° (Czech Republic). The table shows the star name, phase, rating, period, maximum brightness, minimum brightness, amplitude, time of minimum, azimuth, and altitude.

This site serves as temporary replacement for official http://var2.astro.cz/ ephemerides for variable stars; and uses same orbital elements.
