That happens around August each year, and the specific day depends on the geographic latitude and the year. On that particular day, Sirius becomes visible for the first time for a few seconds shortly before sunrise in the morning at the eastern horizon. That day was an essential event for ancient Egyptian civilization, as it indicated the beginning of their new year. A few temples were aligned to that location on the horizon where Sirius appears for the first time each year; most prominently, the Hathor Temple at Dendera, near Luxor. Also, the southern shaft in the Queen's Chamber of the Great Pyramid at Giza is considered, with its 38° angle, to be related to Sirius. Specifically, its upper culmination angle, the maximum elevation above the local horizon it reaches, matches that angle at the time when the pyramid is assumed to have been built. Heliacal Rise shows with a live camera view overlaid visual compass indicator the horizon locations of Sirius's heliacal rising and setting when exploring a location on Earth, along with dates and times. The built-in calculation automatically adjusts to the phone's location and set year. It can also be switched to manual location mode so you can view the heliacal rising for any location on Earth. With version 2, a map view is available when running on iOS/iPadOS 17 and newer, showing the heliacal rising and setting directions overlaid as lines on a global satellite image map for any location on Earth at any year down to 13000 BC into the past. It also shows for Sirius the time and elevation above the local horizon of its yearly midnight culmination on New Year's Day. That's special for the star Sirius to reach its highest nightly location above the horizon only seconds to minutes apart from midnight into the New Year. Every star has its day of the midnight culmination, but they are distributed throughout the year, and only the Sirius Midnight Culmination occurs at midnight into the New Year. Next to the midnight transit also the noon transit is shown and the days since the Sirius Sun Conjunction. If you'd like to see the rising locations of other stars, please let me know which ones. Also contact me, if you have suggestions about other interesting features to add. ## Heliacal Rise Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/31/ea/51/31ea51f1-5177-fcb5-a020-b1019ca600ee/iphone65_dendera_map.png/1242x2688.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/74/8b/39/748b397f-93a8-5203-5d6b-2663808bdd68/iphone65_portrait_dendera.png/1242x2688.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/c3/0d/91/c30d912e-c3d9-53a7-f20b-5cd713998258/v210_ipad13_1776_transit.png/1242x2688.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/34/24/3a/34243ae1-eedf-abd0-cc70-9244e2a0b9c9/iphone65_rise2.png/1242x2688.png) ## Heliacal Rise Available In - [Belgium](https://apptail.io/app/heliacal-rise-zXQx/belgium) - [Switzerland](https://apptail.io/app/heliacal-rise-zXQx/switzerland) - [China](https://apptail.io/app/heliacal-rise-zXQx/china) - [France](https://apptail.io/app/heliacal-rise-zXQx/france) - [Peru](https://apptail.io/app/heliacal-rise-zXQx/peru) - [Portugal](https://apptail.io/app/heliacal-rise-zXQx/portugal) - [Saudi Arabia](https://apptail.io/app/heliacal-rise-zXQx/saudi-arabia) - [Taiwan](https://apptail.io/app/heliacal-rise-zXQx/taiwan) - [United States](https://apptail.io/app/heliacal-rise-zXQx/united-states) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
