The Eta Eridanids meteor shower takes place within the boundaries constellation of Eridanus. The meteor shower occurs between 3 Aug- 14 Aug with the peak occurring on the 09-Aug every year.
The Solar Longitude (Abbrev: S.L., λ ☉) is 137 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 Azha. The coordinates can also be determined by the Right Ascension (43.7) and the Declination (-11.9).
The Zenith Hourly Rate or how many you expect to see during the hour is 6. 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 Eta Eridanids has a very low zenith hourly rate so don't expect anything spectacular like you might see with the Geminids or Perseids. The latter of the two occurs at roughly the same time. They are quite swift at a speed of about 65km/s. Although possible of up to 6 per hour, its more likely that its only one. Ref: IMO
Although attributed to the Chacornac comet, it could also be attributed to Comet Pons-Gambart but the former is more likely to be the source. It is a relatively newly discovered meteor shower compared to other meteor shower. Pons-Gambart return has only be recorded in 1827, it is considered to be a lost comet. Chacornac is a long time period comet whereas Pons-Gambart is about 65 years. Ref: Harvard
Azha, the namesake star is not visible until the early hours of the morning, about 2 a.m. in London and Miami. You don't have much time to see as it gets light quite early because its in summer. The star rises in a East to South-East direction whereas in the south, its just an easterly direction.
Azha rises above the horizon two hours earlier in the southern hemisphere and therefore you have two more hours to view the meteor shower. The star rises in an easterly direction.
