It's quite transient, at very most a two-month window of opportunity, where the real center of the window is two weeks or less. It's not actually super significant. But it really depends on the significance of the Moon in your own chart and what aspects it may make simultaneously. I've been through it not terribly long ago -- early 2016. Nothing memorable in the way of events or personal changes came of it. But I do recall roughly during that time making a shift in how I approached my work, making sure it met my needs and the needs of the people I serve and being far less concerned with drawing attention to it/myself. That's the only thing I can recall that relates to this shift from prog Moon above to below horizon (1st house).
Prog Moon hitting the Asc and going below the horizon starts a new period of emotional attention on subjective concerns first with self and things closer to you, ending about a 14-year period of inner attention on connecting with matters of the objective world (7th through 12th houses); shifting your sensitvity to the internal and away from external triggers, people, etc.
The main challenge is knowing when this actually takes place, because it requires (a) having an accurate Asc figure by sign and degree, which most charts don't have, and (b) using the topocentric position for the Moon. Otherwise, even with an accurate Asc figure to the degree and minute of arc, the common formulas for tracking the Moon can have it off by up to a month.
