Create Timelines with LUNA's Ephemeris Search.

What's an Ephemeris Search?

A powerful tool for finding when planets turn retrograde, aspect one another and change signs and houses.

When searching, you can specify a wide date range so you can easily:

• Follow planetary cycles across decades or centuries.
• Find planetary retrograde (RX) and direct stations.
• Look for rising, culminating and setting times of planets by angle.
• See when planets change signs, including multiple ingress events due to RX motion.
• ...and more!

Plus, you can compose any of your searches into a unified timeline that you can browse, filter and download.

What's in This Guide?

This guide is an introduction to the main features of LUNA's Ephemeris Search. We won't cover every detail of this exciting feature, but we will go through the primary functions by using a specific search as an example.

In this guide, you will learn how to:

1. Create a timeline of lunation cycles throughout a decade.
2. Filter your timeline to only show Aries New Moons.
3. Navigate the charts of your timeline like a slideshow.

1. Create a timeline of lunation cycles throughout a decade.

When you first visit the Ephemeris, you'll see an Aspect search form by default. To calculate the full lunation cycles for an entire decade, you'll want to:

1. Enter your preferred start and end search dates first (I've chosen 01/01/2020 - 01/01/2030).
2. Select the Sun and Moon from the list of planets.
3. From the list of aspects, select at least Conjunction and Opposition, but you may also want to select the Square aspect, too, so you can see the first and third quarter square events.

When searching for aspects, you must select 2 planets; then you can select any number of aspects from either list shown.

Click or tap the "Search Aspects" button and LUNA will take you to your "My Searches" screen with this new search you just created shown as pending (it only takes a few moments to complete).

The length of time it takes to complete your search is based on the date range you set in the form.

Once your search is ready, LUNA will automatically display a timeline of the events that were found based on your input parameters, sorted chronologically from the oldest to the newest event. You can change the sort order by selecting the "Date" link column header.

Notice that LUNA found 495 events for this search between January 2020 - December 2029.

2. Filter your timeline to only show Aries New Moons.

Now that we have almost 500 aspect events, we can apply some filtering to our timeline so only the specific aspects we're interested in seeing will display.

Use the "Keyword Filter" field to enter aries conjunction, then click the "Filter" button.

Our timeline now shows only the conjunctions (i.e. "New Moons") that occur in the sign of Aries throughout our entire search range.

You may have noticed the "Start Date" and "End Date" fields. You can use these in conjunction (pun very much intended) with the "Keyword Filter" to create even more specific filtering of your timeline. All 3 of these filters are optional so feel free to experiment until you get the results you want.

When you apply filters to your timeline, they will show below the filter fields; select one to remove the filter.

3. Navigate the charts of your timeline like a slideshow.

Now that we have our timeline looking the way we want, let's see how to view the charts for these events. You can select any of the entries from the timeline and you'll be taken to the chart for that event. Note that the date, time and location of this chart is based on your home location.

The Timeline Navigator shows details about the event you're viewing, along with easy navigation buttons to move forward and backward across your timeline.

On the chart (or "Horoscope") screen, you'll see a new panel appear below the Spacetime Navigator. The Timeline Navigator is a powerful way to easily navigate across all of the events in your filtered timeline. I'm emphasizing the word "filtered" here because remember that we applied a keyword filter of aries conjunction to our timeline. Now if you click forwards or backwards in the Timeline Navigator, all of the events that you were just viewing will load into the chart automatically for you one at a time, according to the order you saw them appear in your timeline (the previous screen).

You can easily return to your timeline by selecting the "Back to Timeline" text link.

The chart in view is not related to this event so it's showing as inactive. Select "Reload Event" to view the chart for this event.

One more important point to make here is that you can navigate away from this event via the Spacetime Navigator. When you do, the event in the Timeline Navigator fades out a little and you will see a "Reload Event" button. This indicates that you are no longer viewing the event that's showing in the Timeline Navigator, but can easily return to it at anytime.

Select the "Close Panel" text link to remove the Timeline Navigator from your screen. You can go back to the Ephemeris > My Searches screen at any time to view your previously completed searches and compose a new timeline.

More to Discover...

While this guide provided you with an overview of how LUNA's Ephemeris Search works, it's worth reviewing the Knowledge Base to read more about what's possible.

For instance, you can:

• Combine Mercury retrograde and direct stations onto the same timeline as Sun-Mercury conjunctions, which will allow you to view the entire Sun-Mercury cycle more clearly.
• Combine Pluto ingresses into Capricorn and Aquarius onto the same timeline as Pluto retrograde and direct stations to easily track its movement over the next couple of years.
• Download your timeline as a Calendar (ICS) or Spreadsheet (CSV) file so you can integrate the events with other tools and analysis.
