The Pisciden (named after the constellation Pisces, Latin Pisces ) are a meteor shower that occurs in September , the shooting stars of which seem to come from the constellation of Pisces .
In contrast to most of the other swarms of shooting stars , the best time to observe the Piscides is not in the morning sky , but around midnight , when the constellation is almost in the south.
The radian of the Piscids, active from August 16 to October 8, is close to the spring equinox - but in a star-poor region - at the approximate celestial coordinates 0:20 h / + 2 °. According to recent sources of electricity is only 1 to 30 September, a significant number Meteor and other ecliptic showers under the term Anthelion summarized current.
The maximum number of shooting stars that fly relatively slowly (at around 26 km / s), the so-called Zenithal Hourly Rate (ZHR), is around 3 to 5 per hour at its maximum around September 12th to 15th, but it is too far north in ours Widths not quite reached. The maximum is very flat because the shooting stars belong to the ecliptical type, that is, they are relatively far in the plane of the earth's orbit.
