The September Epsilon Perseids meteor shower takes place within the boundaries constellation of Perseus. The meteor shower occurs between 5 Sep- 21 Sep with the peak occurring 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 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.
The advantage of the northern hemisphere is that you don't have to stay awake as long as the southern hemisphere. Whilst they are visible about 8 p.m., its probably best to wait until 9 p.m. when you can fully appreciate them as it is darker. The Perseids over the days will track a path below Algol rather than Epsilon Persei.
For viewing in the southern hemisphere, you will need to be awake in the very small hours of the morning looking not very high up from the horizon. The best time is from 1 o'clock to 6 o'clock. You will need to look in a north easterly direction but as the morning grows, look more towards the north and then north-westerly.
From the the 5th, you need to look just below 16 Persei to see the first meteor shower.
The image below was created using Stellarium, an awesome free astronomy program. The picture shows the location of the September Epsilon Perseids on the 9th September in the northern hemisphere. For the southern hemisphere, swap the constellation upside down.
