Mercury enters Virgo, one of the two signs it rules, Friday at 12:44 pm EDT (16:44 UT). This brings some stability to our mental processes, but also the potential for perfectionism, criticism and a tendency to try and understand the world — driven as it is by emotion and belief — through logic alone. In neighboring Leo, however, we find some balancing energy.
Venus, newly in Leo, is approaching a conjunction to Jupiter (exact Monday at 1:21 am EDT / 5:21 UT, but in effect now). Venus-Jupiter conjunctions are generally thought to be lucky or beneficial, even if sometimes prone to extravagance or overindulgence. Particularly in Leo, Venus-Jupiter is going to magnify compassion, loyalty and effusiveness — even to the point of getting caught up in the display of such impulses above and beyond what is thoroughly genuine or necessary.
Virgo and Leo are neighboring signs; as such, they are very different in many ways: Virgo is mutable earth; Leo is fixed fire. Yet at their best, both signs orient quite effectively on serving humanity. (At their worst, pickiness and pride, respectively, can be their undoing.)
