Glossary Equinox: either of the two points on the celestial sphere at which the ecliptic intersects the celestial equator; also, the time at which the Sun passes through either of these intersection points; i.e., when the apparent longitude of the Sun is 0o or 180o. Solstice: either of the two points on the ecliptic at which the apparent longitude of the Sun is 90o or 270o; also, the time at which the Sun is at either point.

Note: Time in every page is UT (universal time). For Kyiv Local_Time=UT+2h (and Local_Time=UT+3h for summer time).
