The Piscis Austrinids meteor shower takes place within the boundaries constellation of Piscis Austrinus. The meteor shower occurs between 15 Jul- 10 Aug with the peak occuring on the 28-Jul every year.
The Solar Longitude (Abbrev: S.L., λ ☉) is 136 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 Piscis Austrinids are a faint meteor Shower that radiate from an area to the west of the brightest star Fomalhaut in the constellation of Piscis Austrinus, the southern fish. If you`re expecting something quite spectacular, you will be severly disappointed with what you get, the most you could probably get is about 10 (1). Also happening at the same time is the Southern Delta-Aquariids which is also a faint meteor shower so where the meteor is credited can be somethings wrong.
The closest star to the radiant point of the meteor shower is Fomalhaut. The coordinates can also be determined by the Right Ascension (352.5) and the Declination (-20.5).
The Zenith Hourly Rate or how many you expect to see during the hour is 5. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 44 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.
