An annular eclipse is from 9 degree 55 to 11 degrees 15 minutes and partial runs from 11 degrees 15 minutes to the limit of 18 degrees 31 minutes. The lunar eclipses, at full moon, have a narrower margin. A partial lunar eclipse must be 12 degrees 15 minutes or less from one of the nodes and a total eclipse must be closer than 9 degrees 30 minutes. In the birth chart of a person or an entity such as an organization or a nation, the dragon has some very specific uses that no planet provides. It brings fame, recognition, success and opportunity, as well as disgrace and public humiliation.

When two people are looking to the astrologer to see if their romance is going anywhere, the nodes will tell the story. All enduring relationships that I have ever seen have some kind of nodal ties from one chart to the other. Any relationship without them simply does not last. I have seen this repeatedly in decades of doing charts. Such contacts are lifelong ties and no matter how much time has passed since people have seen each other, the power of the node will reawaken the relationship very readily.
