August 11, 2022 Tonight's Full Moon sits in the Sky right next to Saturn - both in the constellation Capricorn - "The Sea Goat". Just after the sun sets on your western horizon, look east to watch Saturn and then the moon rise (about 15 - 20 min after sunset).
August 12, 2022 Look to the eastern horizon at dawn to catch your first glimpse of Sirius in the dawn sky. This first viewing of a star before sunrise is called the Heliacal Rising.
The Heliacal Rising of Sirius was celebrated as a "new year" in ancient Egyptian cultures, as it came to be known as an indicator of the flood season of the Nile River and signified the start of the growing season in that region.
Take note that Venus will also be rising around the same time on this day, and will be visible before Sirius, and likely much brighter. You will need to distinguish the two - Venus rises north of east, and will be quite bright. Sirius rises 20 minutes or so later that Venus, and will sit south of east on the horizon.
The Heliacal rising of a star is dependent on your earth latitude. At my latitude of 41-42 deg, the heliacal rise is around August 12, yours might be a few days prior or later, depending on you location and the horizon line visibility.
