What does the ingress actually mark?
The Sun’s apparent longitude reaches 240 degrees, the start of tropical Sagittarius, on 22 November 2026 at 07:23 UTC. The solar ingress table puts the next gate, tropical Capricorn, at the solstice on 21 December at 20:50 UTC. A sign here is a thirty-degree slice of that path. It is not the constellation behind it, and it is not a description of a person.
The Indian solar gate into Makara is Makar Sankranti in January, weeks later, because that calendar uses a sidereal zodiac. The Sagittarius page stays with the coordinate. Mercury follows on 6 December.
