Jupiter (expansion) enters Virgo on August 11th, for a tour that lasts until September 9th, 2016.
Virgo is about details, but Jupiter likes to go big. Mix the two, and you get lots of details. An increase in awareness of what needs to be improved (which goes hand in hand with an awareness of what's broken or missing). An increase in critical information. An increase in the desire/ability to make things better.
This can be an extremely productive transit, for those ready to work. It can also be a nit-picky transit, as Jupiter's inflated expectations magnify Virgo's craving for perfection. With any Jupiter transit, you must exercise moderation. Yes, even in Virgo. You can make things better (in the Virgo area of your chart) but watch out for self-righteousness, relentless nagging, and flurries of OCD.
Jupiter can bring benefits, of the Virgo variety. Opportunities to help, heal and serve. Opportunities to cleanse, focus or launch a self-improvement regime. Opportunities to make the most out of something you've been crafting. Jupiter can launch a project you've been labouring over, giving you your day in the sun. This transit can help humble Virgo achieve recognition, by adding a flourish to certain details.
Think of the intricacies in a Gothic cathedral; detail is elevated and becomes a conduit to something beyond the mundane.
Of particular note, August 11th to 15th will see a conjunction between Jupiter and Regulus, at 0 degrees Virgo. Jupiter's union with this fixed star will expand the theme of power that comes from doing the right thing. This will coincide with Venus Rx's conjunction with the Sun in Leo (August 15th), marking a new phase of the Venus synodic cycle. So we have a significant new beginning, especially for anyone with anything at 0 degrees of the Mutable signs, or 22 degrees of the Fixed signs. The focus will be on correct behaviour involving relationships, finances or personal values. Note that "correct" does not mean what's socially polite. In this case, it means what's honourable and what aligns with higher intentions. Doing what you know is the right thing to do, even if it's not fun. Details will be supremely important here...the little things you think no one will notice (but they do).
As this transit progresses, I'll write about the aspects Jupiter in Virgo will make. For now, know that the best use of this energy is to be aware of what needs fixing, but don't obsessively dig for flaws. Jupiter makes things big and obvious; if something's broken, you won't have to hunt for it.
