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 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 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.
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 majority of Cygnus the swan is visible the whole of year in the Northern Hemisphere. The further south you go, the less you are going to see it. Kappa Cygni is part of the Cygnus that is always visible. The meteor shower should be visible as soon as it gets dark, there's no need to wait.
Although the meteor shower is named after a star in Cygnus, the meteorites are more likely to be seen in the Draco constellation boundary. The radiant point is in the middle of a line between HIP 91606 and Iota Cygni.
The best time to view the meteor shower is after 10 o'clock when it is dark. It will be harder to see earlier due to the light from the Sun as it sets. You need to look up in a northerly direction. It should be a little higher above Ursa Minor constellation which contains the Pole Star.
The more south you are, the more unlikely you are going to be able to see the Kappa-Cygnids. If you are in Quito, Ecuador, you should be able to see the meteor shower from when it gets dark to about 2 a.m. but any further south, you chances are limited.
