In the second half of March, the planet Mercury is located exactly on the ecliptic, 10 ° east of the Sun. At what latitude is it easiest to find it with the naked eye or with binoculars?

Mercury is in eastern elongation, which means it can be found in the early evening at sunset or just after sunset. Obviously, with a fixed angular distance from the Sun, it will be easier to find it where it will be located exactly above the incoming sun, that is, in the place where the ecliptic will be perpendicular to the horizon and pass through the zenith.
Since it happens in the evening in the second half of March, the setting Sun is located near the vernal equinox near the horizon. At the zenith then there will be a point of the summer solstice, located 90 ° to the east from it, that is, it will be the northern tropic with latitude φ = + 23.5
