On September 9th Mercury is retrograde at 8 degrees. Mercury retrograde is the planet moving back and forth slowly. It is a fluctuating retrograde loop moving past normal boundaries of the elliptic. The retrograde movement is an obstruction that you must progress through. Mercury retrograde is a time of redo and review. Mercury is retrograde first in Libra and then it goes back into Virgo on September 24th. It continues its retrograde movement until October 2nd when it will go direct.
Mercury is also trine Mars, normally I would say this is an excellent time for all mental work and negotiations, but with Mercury retrograde, it has obstacles to jump through before you can get to the finish line. The goal of this transit is to slow down.
The Moon will be square to Mars too, this aspect moves quickly. It can make you feel this irritable. It is best not to make rash decisions
