I wanted to know when Sirius was hitting the meridian. When it culminates will be the best time to try to view the double star and it the dim companion. Started in Stellarium and used the sidereal day advance but that was too slow.
Opened ST3P. I used the Ephemeris tab in the app requesting the best time to view the brightest star in the night sky.
