During the time of any retrograde, it is important to slow down and review the progress made that relates to the energy of the retrograde planet. When it is weaker (retrograde), there is an opportunity to defend or stand by earlier decisions.
There are two retrograde planets in June:

Mercury June 29 – July 23
It is a good idea to prepare for any Mercury retrograde by taking care of as much as you can about a week prior to the actual retrograde. This will help minimize challenges with the things ruled by Mercury such as mix-ups in communications, delays in orders, transportation/travel glitches, electronic equipment breakdowns (computers, appliances, etc) and a slow down in business. A note regarding business: many experience a drop in business during this time. However, there are just as many that experience an increase in business and usually they are OLD customers or clients returning. This is a good thing under a retrograde. Many find that outstanding or pending litigations can be settled during the retrograde. Reconciliations are common. Reconnecting with people you have not heard from in quite a while will suddenly reach out. Returning to a former employer is possible. Pay strict attention to any financial dealings during this time. Mistakes could be costly.

Pluto – May 6 – October 16
Pluto will retrograde at 5 degrees Aquarius backing up to 3 degrees before moving forward again. It is time to review those things related to major transformation, death, and rebirth. Transformations can come about due to wars, disasters, losses of all kinds like your job or home. In Aquarius, these transformations might relate to airplanes, space travel, aliens, inventions, technology, etc. On a personal note, you may be working on a relationship or changing “chairs” at work or perhaps changing your travel plans. Now is the time to revisit those things and make appropriate adjustments. You have time as this window for review lasts until October! Those born under the sign of Scorpio may feel fatigued in June but by mid-July, you will perk up and feel energized.
