The Northern Delta Aquariids meteor shower takes place within the boundaries constellation of the Aquarius. The meteor showers occurs between July 16-Sepember 10 with the peak occuring on the Aug. 13/14 every year The Solar Longitude, mistakenly known as Lambda Omicron is 141 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 Marsden and Kracht Sungrazing . The closest star to the radiant point of the meteor shower is Skat. The coordinates can also be determined by the Right Ascension (347.6) and the Declination (2.1).
The speed/velocity of the Meteor Shower particles is 38 km/s.
