The meteor shower occurs between Jul 03 - Aug 15 with the peak occurring on the Jul 30 every year.
The meteor shower peaks on the Jul 30 every year.
The Solar Longitude (Abbrev: S.L., λ ☉) is 127 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 Comet 169P/NEAT. The closest star to the radiant point of the meteor shower is Algiedi Prima. The coordinates can also be determined by the Right Ascension (306.5) and the Declination (-9.2).
The Zenith Hourly Rate or how many you expect to see during the hour is 4. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 23 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 Alpha Capricornids is a meteor shower whose radiant point moves across the sky. It is closest to its namesake star on or around about the 27th of July, before that the radiant point is is in nearby Sagittarius. The radiant point comes closest to Albali in nearby Aquarius. The Alphas
The Alphas are best seen after dark so we're talking about after 11 p.m. in the night until about four o'clock the next morning when the sun is about to rise. It is not far off the horizon if you're in London for example.
Like the Northern Hemisphere, the radiant point moves across the sky over successive nights. It is more easier to spot in the southern hemisphere due to it being higher in the sky.
