Piscis Austrinids Meteor Shower

When and where does the Piscis Austrinids Meteor Shower Occur

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 occurring 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 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).

Zenith Hourly Rate

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.

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 severely disappointed with what you get, the most you could probably get is about 10. 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 sometimes be wrong.

How to Find and View the Piscis Austrinids

The Piscis Austrinids are viewable from about 8 p.m. when it has turned dark. Look in a south easterly direction not far up from the horizon and you should spot them. The meteor shower should be visible through out the night until the morning when the light from the Sun will block out all the faint shooting stars.

In the northern hemisphere (London), the Piscis Austrinids should be visible just above the horizon from about 1 am to 4 p.m. If you live north of London, you are really going to struggle to see them. At the same time, there are other easier to see meteor showers to be spotted which are higher in the sky.
