The Kappa Serpentids meteor shower takes place within the boundaries constellation of the Serpens. The meteor showers occurs between 1 Apr- 7 Apr with the peak occuring on the 05-Apr every year The Solar Longitude, mistakenly known as Lambda Omicron is 20 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 closest star to the radiant point of the meteor shower is Kappa Serpentis. The coordinates can also be determined by the Right Ascension (240.2) and the Declination (16.8).
The Zenith Hourly Rate or how many you expect to see during the hour is 4. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 47 km/s.
