Westminster Bridge and Palace of Westminster on the west bank of the Thames were the sites of the terrorist attack. For mophogenetic field level 3 Westminster Bridge leads from Leo on the Westminster Palace side of the river into Virgo. That means the attacker drove from Virgo into Leo. The astrogeographical latitude coordinate lies in Scorpio. During the attack the ascendant moved through the last degrees of Leo. ph: Daniel Bron, ccbysa3.0
