Events Help

The Event Finder is a powerful search engine that finds astronomical events visible tonight and far into the future. The finder dynamically generates a listing of moon phases, eclipses, Jupiter satellite events, meteor showers and planetary phenomenon such as conjunctions, elongations and oppositions to name but a few of the events that can be displayed.

You open the Event Finder by tapping Observe in the Toolbar and selecting Events.

Events by Date: By default, the list of events is created for a week in advance from today's date. Tap Start Date and End Date to search for astronomical events on a specific date range. After setting your dates, SkySafari dynamically updates and generates a list of events.

Note: Creating a list of events for a long date range requires a greater amount of time to calculate. For faster searches limit the date range to a few months.

Viewing Events: Tap on an event in the list of generated events to simulate the event in SkySafari.
