The Sigma Leonids meteor shower takes place within the boundaries constellation of the Leo. The meteor showers occurs between 9-Feb - 13 Mar with the peak occuring on the Feb 25 - 26 every year The Solar Longitude, mistakenly known as Lambda Omicron is 23 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 2002 GM5?. The closest star to the radiant point of the meteor shower is Sigma Leonis. The coordinates can also be determined by the Right Ascension (199.5) and the Declination (3.6).
The speed/velocity of the Meteor Shower particles is 23 km/s.
