I just found this feature on astro.com (A recent addition) that you can add Post and Pre Natal Solar and Lunar Eclipses. At first I thought why would they have an affect on you?
But then I realized it is just like the nodes of the moon, but potentially stronger.
The nodes of the moon are created by the points where the physical body of the moon crosses the path of the energy left behind from the motion of the physical planets and the Sun.
The sun would be the main contributor to the creation of the ecliptic energy. So the point where the moon and the sun previously crossed each other would be very powerful.
