Of the 13 zodiacal constellations (constellations that contain the Sun during the course of the year), Ophiuchus is the only one not counted as an astrological sign. It is also known as the "Sign of the Crossing", representing the intersection of the celestial and heavenly spheres.
Ophiuchus is located between Aquila, Serpens and Hercules, northwest of the center of the Milky Way. The southern part lies between Scorpius to the west and Sagittarius to the east.
This is precisely the position Planet X would assume following a passage from beneath the ecliptic upon initiating its return sojourn toward the unlit binary sun of our solar system.
"The Christmas Hammer is caused in great part by the December switch in Magnetic Trimester which occurs, as we have explained, at approximately December 17 on the Earth calendar. This forces a magnetic adjustment in all magnetic planets, and great stress on the Earth which is locked into a magnetic dance with Planet X." ZetaTalk
