Conjunction
Two planets in roughly the same place, give or take a few degrees. The strongest aspect. The two meanings fuse. The familiar New Moon is just the Sun and Moon in conjunction.
A conjunction is when two planets are at the same point in the zodiac, within a few degrees of each other. It is the strongest aspect in classical astrology because the two planet-meanings do not just talk to each other — they fuse. Whatever the two planets mean separately, in conjunction they speak as one combined voice.
The most familiar conjunction is the New Moon: the Sun and Moon at the same zodiac longitude. Beginning of a cycle, fresh page. A Mercury–Venus conjunction warms communication with charm. A Mars–Saturn conjunction discipline-tests anger. The flavour of the combined voice is always specific to the pair.
In a daily forecast AIstra flags exact conjunctions because they tend to mark felt moments: the day the conversation actually happens, not the week before or after. The orb she uses is 3°. Closer than that, and the fusion is unmistakable.
