The date (near March 21 in the northern hemisphere) when night and day are nearly the same length and Sun crosses the celestial equator (i.e., declination 0) moving northward. In the southern hemisphere, the vernal equinox corresponds to the center of the Sun crossing the celestial equator moving southward and occurs on the date of the northern autumnal equinox. The vernal equinox marks the first day of the season of spring.

The Lyrid meteor shower will reach its maximum rate of activity. Some meteors will be visible each night from 16 Apr to 25 Apr, but the best show will be after midnight on April 22. The maximum number of meteors expected to be visible from a dark location is around 10 per hour (ZHR). The 2nd quarter moon will wash out some meteors, but the brightest ones will shine through.
