About the Alpha Capricornids
The Alpha Capricornids are caused by Earth crossing the trail of dust left by 169P/NEAT. The meteors appear to stream from a point called the radiant, at right ascension 307° and declination -10°, and hit the atmosphere at about 23 km/s. The peak is defined by the Sun's ecliptic longitude of 127°, which is why the date shifts slightly from year to year.
The zenithal hourly rate of 5 assumes a perfectly dark sky with the radiant overhead. From most locations expect fewer, and far fewer if the Moon is bright. With a southern radiant this shower favours the southern hemisphere and the tropics.
