The meteor showers occurs between Oct 9-25 with the peak occuring on the Oct 17 every year The Solar Longitude, mistakenly known as Lambda Omicron is 206 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.
