The Solar Longitude (Abbrev: S.L., λ ☉) is 186 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 .
Delta Aurigids are a minor annual Meteor Shower. The source of the meteors is unknown and it has a low rate of hits which could imply that the source is a long period comet and therefore its not been been here for some time as the meteors debris is getting fewer and fewer.
The closest star to the radiant point of the meteor shower is Delta Aurigae. The coordinates can also be determined by the Right Ascension (82) and the Declination (49).
The Zenith Hourly Rate or how many you expect to see during the hour is 3. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 64 km/s. The population index of the meteor shower is 3. The population index refers to the magnitude distribution of the meteorites, the smaller the index, the brighter the meteors are, the higher, the dimmer the meteors are. For this particular meteor shower, bright meteors are more frequent.
