The Solar Longitude (Abbrev: S.L., λ ☉) is 39 degrees, this value 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 .
Camelopardalids are a northern hemisphere meteor Shower whose radiant point falls within the Camelopardalisconstellation border. The meteor radiant point is close to the border with the Ursa Minor, the little bear and its brightest star Polaris, the North Star.
The meteor shower is associated with a short period comet, 209P/Linear which had only recently been identified as a comet, previous thought of as an asteroid because there was no tail. The comet has a relative short period of 5.06 years to orbit the sun.
The source of the meteor shower is Comet 209P/LINEAR. The coordinates can also be determined by the Right Ascension (170.9) and the Declination (76.8).
The Zenith Hourly Rate or how many you expect to see during the hour is 2. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 14 km/s.
