Kappa Cygnids Meteor Shower

The Kappa Cygnids meteor shower takes place within the boundaries constellation of Cygnus. The meteor shower occurs between Aug 03 - Aug 25 with the peak occurring on the Aug 17 every year.

The meteor shower occurs between Aug 03 - Aug 25 with the peak occurring on the Aug 17 every year.

The meteor shower peaks on the Aug 17 every year.

The Solar Longitude (Abbrev: S.L., λ ☉) is 141 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 Kappa Cygnids are a minor meteor shower that occur at about the same time as the Perseids meteor shower which are more frequent and brighter. The name comes from the fact that the radiant point is close to Kappa Cygni The star is within the boundaries of the constellation but is not part of the actual constellation.

The closest star to the radiant point of the meteor shower is Kappa Cygni. The coordinates can also be determined by the Right Ascension (277.5) and the Declination (52.8).

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 21 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.
