I've tried to research this placement, but only seem to find it's effects in synastry charts, and very little information on how (or if) it affects on an individual's chart.
I read on cafeastrology.com that "...the Vertex and the Nodes of the Moon prominent when important contacts are made in regards to solar returns".
Well, I have Vertex sitting right on Algol in the 8th house in my solar return (which will begin on Nov. 2nd) and what I know of those three things are:
-Vertex: fated event and/or meeting
-Caput Algol: "Very unfortunate star, Primitive female sexualityviolence, mass catastrophe; the "Evil One", the Demon Star; passionate; intense; hysterical.
(http://www.astrologycom.com/fixedstars.html#Taurus)"
-8th house: Cycles of Deaths And Rebirth. Sexual relationships and deeply committed relationships, regeneration, joint ventures or funds...
So my guess is that I will have a quite intense fated encounter with someone sometime during my solar year. Would that be ballpark interpretation?
Soooo...my questions are:
1. Can Algol's influence be "activated" by a non-planetary influence, such as the vertex?
2. Being about 5 degrees or so away, can I conclude that Vertex is on the Gemini cusp and should interpret it's placement in Gemini (as opposed to Taurus)?
3. Is it possible to find the timing of this influence ( a ballpark figure as to when it will happen) in a solar return?
(i.e. could I use the same equation, with timing using the moon, as I do with, say for example, an horary chart?)
4. Would looking at any other aspects in my solar chart determine if this "fated encounter/event" will be negative or positive or it's effects (if any)?
( A "no, it doesn't matter", or "yes, it could help" answer would be great, I'm not looking for a full interp. of the aspects/effects

)
Any insight would be truly appreciated!
I attached my solar chart for the purposes of providing a visual of this aspect, focusing on the Vertex/Algol questions.
