The meteor shower occurs between July 9-17 with the peak occurring on the Jul. 14/15 every year.
The meteor shower peaks on the Jul. 14/15 every year.
The Solar Longitude (Abbrev: S.L., λ ☉) is 110.3 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 coordinates can also be determined by the Right Ascension (31.6) and the Declination (-47.7).
The Zenith Hourly Rate or how many you expect to see during the hour is 4. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 47 km/s.
Most meteor showers are known by the nearest star to the radiant point but the July Pheonicids, its named after the month in which it occurs. The estimated nearest star based on the right ascension and declination is Psi Phoenicis which is located at the base of the constellation so to speak.
You are going to have to be in the southern part of the northern hemisphere to see this constellation and meteor shower. If you are in Miami, you may well just be able to see it about four a.m. and then only for a few hours before the Sun rises and blocks out the view.
Whilst the constellation is visible starting from 8 p.m., the closest star is not visible until after 10 p.m. and then is visible for the rest of the night.
