f_{1 }= r_{1 }= x_{1} (event; perhaps: spacetime coordinates) is a solstice of extreme r_{3 }= x_{2} ("ka" construct or season; default: "ka zmadu", which means "Summer solstice", unless context makes this interpretation untenable) at location/of or for celestial body/object d_{3 }= x_{3} with respect to orbit/sun x_{4}.

x_{3} is akin to donri_{2}, but is more relevant to the concept of a solstice and the orbital mechanics which may be involved. Use "dunraisa" etc. for some amount of neutrality and objectivity concerning location and any biases which may be at play therefor. For a clever calque of English "soltstice", see: "solsta". See also: "dornilteikeznulfau", "3 = x_{3} with respect to orbit/sun x_{4}.">ctenilteikezraifau".
