What does this ingress mark?
The solar table puts the Sun into tropical Aquarius on 20 January 2027 at 07:29 UTC and into Pisces on 18 February at 21:33 UTC. Capricorn season began at the solstice. Sidereal Makar Sankranti was 15 January and uses a different zodiac. The sign here is a coordinate.
Mercury stations retrograde on 9 February, while the Sun is still in this slice. The page is the ingress. The retrograde has its own dates.
