The Daytime Zeta Perseids meteor shower takes place within the boundaries constellation of the Perseus. The meteor showers occurs between 20 May- 5 Jul with the peak occuring on the 09-Jun every year The Solar Longitude, mistakenly known as Lambda Omicron is 74.5 degrees. This value sometimes expressed as S.L. or λ ☉ is the the date of maximum activity. It is measured as a degree with zero degree indicating spring equinox (roughly March 21st/22nd). 90 is the Summer Solstice, 180 is the Autumn Equinox and 270 is the Winter Solstice. This degree is independent of the calender. AMS .
The source of the meteor shower is 2P/Encke. The closest star to the radiant point of the meteor shower is Menkib. The coordinates can also be determined by the Right Ascension (67.4) and the Declination (23.4).
The Zenith Hourly Rate or how many you expect to see during the hour is 20. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 26 km/s.
