On 26 September the Moon is full in Aries. This is where a lunar cycle reaches maturity, and it does so with the force of the first sign of the zodiac: whatever has been asking for room for two weeks stops waiting now.
What is happening
Aries is cardinal Fire, the sign that opens the zodiac and for that reason focuses entirely on itself: the raw force of life breaking loose with no order and no plan. With the Full Moon here, what you feel demands to come out right away, directly, often precisely when you are facing someone else. Mars and Pluto rule here and the Sun is exalted: the drive to act is among the strongest of the year.
Venus is in detriment and Saturn in fall: these days you lack the patience and softness that usually dampen an impulse, and the reaction comes before the calculation. This is a Moon that burns fast, not one that plans: it gives you the charge to act now, but little patience for waiting for things to settle on their own.
How to use it
If you were born at the Full Moon, or in the three and a half days after it, this phase resembles you more closely: clarity comes to you through facing someone else, and these days make it more immediate and less filtered. For everyone, the same invitation applies: if something has been on hold out of too much caution, this is when you find the nerve to say it or do it, before the moment passes.
Where it pays to watch out is the hot, impulsive reaction, especially inside a relationship. These days it is easy to mistake your first response for the final truth, when it is only the loudest one. Before you say something you cannot take back, let a few hours pass: if the urgency is still there, it was real; if it fades, it was only the flame of the moment.
Where you feel it most
If your Sun, Moon, Ascendant or Mars is in Aries, or in one of the other cardinal signs (Cancer, Libra, Capricorn), you feel this Full Moon directly: more impulsive than usual, more inclined to react before you think. For everyone else, what matters is the house of your birth chart this Moon falls in: that is where something asks to be dealt with right now these days, with no more putting it off.
