Pallas' orbital points and their indications in heliocentric sidereal Astrology
orbit and points, dates etc. from my own researches - I needed a lot of coffee, so please consider to buy me one in order to support my work... 

In her orbit, Pallas reaches almost 35 degrees of latitude in both directions, which means that her orbit does follow a path that brings her far away from the ecliptic and their constellations at times....

From her southnode in late sidereal Aquarius, under the circlet of Pisces, she descends south of the ecliptic, through parts of Pisces and Cetus and then along Eridanus to reach its "origin" near Rigel of Orion and a few degrees passed her most southern point in late sidereal Taurus / constellation Orion. 
This is her concluding, letting go and seeding quarter of orbit - it brings her from the "full flow" into the more quiet, introspective waters and same time discerning and preparing. In Cetus the more "collective consciousness" is seen,  their entrapments as well as their beauty and her path through Eridanus brings her into "dangerous situations" when passing in front of the void. 

She then reaches the "origin" of the river Eridanus near the star Rigel of Orion and just a few degrees further, her most southern point of orbit. Meeting an "origin" is truly changing, life altering and brings often a change of the structure or perception of the own fundament - may that now be, that one wants a solution to a "behavior or outcome", the origin is of importance and same might be true in "ancestral" questions or simply generally. 
Her most southern point indicates to be standing true to self and in some kind of "equilibrium", balanced etc.

Through the other leg of Orion (star Saiph), she slowly ascends through the constellation Monoceros (the Unicorn) and its mythical experiences, the constellation Hydra and Sextans, which is "re-orientating energy" to come out onto the ecliptic (her northnode) in late sidereal Leo. In late Leo we find very strong energy, very creative and it can't be hold back... 
During this quarter, while in sidereal Cancer, in the constellation Hydra there's also Pallas' perihelion - indicating that her most influence comes from within and includes the need to face the own fears or "monsters from the past".  

The next quarter of orbit brings her through parts of sidereal Virgo (soul awareness) and to her discovery placement, then northwards to Bootes (unity of feminine and masculine principles), through Hercules (commitment to the "work needed") to her most northern placement at the star Rasalhague of Ophiuchus (illumination through integration of wisdom gained and applied).

Yes, her most northern point is only the "opposition", the "blooming or full Moon" part of the cycle of orbit - she needs now to descend again, to meet her southnode and this path brings her through the constellation of the Serpent's tail and then through the constellation Aquila the Eagle, which brings focused concentration to a goal. She continues still pretty north into the little Foal constellation (Equuleus - Orcus traverses through here too) with its energy of concern for future generations and finally descends through Aquarius to her southnode....
