Alpha Capricornid meteors

Astronomy
  • A meteor shower of generally low activity (maximum ZHR 10) between July 3 and August 15. There appear to be several maxima, the principal one around July 30. Alpha Capricornid meteors are often long, slow, and bright. At maximum, the radiant lies at RA 20h 28m, dec. −10°. The parent body has been identified as comet 169P/NEAT. The Alpha Capricornids are predicted to become a major annual shower, stronger than any current shower, in the years 2220–2420, when the Earth encounters a dense stream of material from the parent body.
