Mercury will go retrograde June 26th and will go direct on July 29. Since Cancer is a water sign and is the ruler of the fourth house, special attention should be spend within the areas of the home, such as actual dwelling, domestic issues and some aspects with the family.
Look in your chart and find which house which is ruled by Cancer and then in which the moon is in. These two clues will indicate where to expect the greatest effect. For Example if Cancer in on your ASC and the Moon is in Aquarius, you can expect issues of independence in the way you express yourself to the world or in the very way you project your self during this time. Family issues will arise in terms of the way your and your relationships will be analyzed. For example, are you having trouble getting the personal freedom to express what you really want to achieve in finding inter-face with others in your family or with your friends who function like family.
With Cancer on the Ascendant, your twelfth house will also be active as no doubt Mercury will regress over your ascendant. This will bring up memories of past situations in the family where you expressed suppression of you’re your growth because of some family problem or parenting issue you have had.
While I cannot go through the many combinations this may take, but use this formula – Where is Cancer in my chart? Where is the Moon? What degrees in my chart will this regression actually cross?
If you do not know this information, or the astrology presented here is beyond your present level of study, just look to domestic issues of family, home, domestic situations in extended family, trips to relatives, siblings, great concepts of what a family should be. Watch the home electronics as this is usually the time that computer, etc will act up.
Finally, memories of upbringing, past family issues may be a more pressing concern during this period. It has been suggested by some that travel might be difficult, but if we must travel during these periods, great care needs to be taken, all schedules checked, tickets, air line delays. ETC.
