The meteor shower peaks on the 09-Sep every year.
The Solar Longitude (Abbrev: S.L., λ ☉) is 168 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 Epsilon Persei. The coordinates can also be determined by the Right Ascension (48.6) and the Declination (39.6).
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 65 km/s.
The application Stellarium puts the meteor shower radiant point as being close to Algol which is the second brightest star in the constellation. The name would however imply its radiant point should be located nearer Epsilon Persei.
