Alpha Capricornids is a meteor shower
Meteor Activity Outlook for July 15-August 10, 2020
Alpha Capricornids is a meteor shower visible rates usually around 3 per hour. That takes place as early as 15 July and continues until around 10 August. The meteor shower was discovered by Hungarian astronomer Miklos von Konkoly-Thege in 1871. This shower has infrequent but relatively bright meteors, with some fireballs. The parent body is comet 169P/NEAT. Minor planet 2002 EX12 (=comet 169P/NEAT) is identified as the parent body of the alpha Capricornid shower, based on a good agreement in the calculated and observed direction and speed of the approaching meteoroids for ejecta 4500-5000 years ago. The meteoroids that come to within 0.05 AU of Earth's orbit show the correct radiant position, radiant drift, approach speed, radiant dispersion, duration of the activity, and distribution of dust at the other node, but meteoroids ejected 5000 years ago by previously proposed parent bodies do not.
