Eta Lyrids Meteor Shower

The Eta Lyrids meteor shower takes place within the boundaries constellation of Lyra. The meteor shower occurs between May 03 - May 12 with the peak occuring on the May 09 every year.

The Solar Longitude (Abbrev: S.L., λ ☉) is 49 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 .

The source of the meteor shower is C/1983 H1 (IRAS-Araki-Alcock). The closest star to the radiant point of the meteor shower is Aladfar. The coordinates can also be determined by the Right Ascension (289.9) and the Declination (43.4).

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 44 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.
