191:. The shower is visible from about April 19 to about May 28 each year with peak activity on or around May 5. Unlike most major annual meteor showers, there is no sharp peak for this shower, but rather a broad maximum with good rates that last approximately one week centered on May 5. The meteors we currently see as members of the Eta Aquariid shower separated from Halley's Comet hundreds of years ago. The current orbit of Halley's Comet does not pass close enough to the Earth to be a source of meteoric activity.

237:. The shower peaks at about a rate of around a meteor per minute, although such rates are rarely seen from northern latitudes due to the low altitude of the radiant. The Eta Aquariids are best viewed in the pre-dawn hours away from the glow of city lights. For northern observers, the radiant of the shower is only above the horizon for the few hours before dawn, and early-rising observers are often rewarded with rates that climb as the radiant rises before sunrise. The shower is best viewed from the
248:(ZHR) exceeded the average level significantly for about two days. An explanation was presented by Mikiya Sato (Sato & Watanabe, 2013), showing that the meteoroids are from a very old ejection from the parent Halley's Comet and are in resonances to Jupiter's orbit (similar to the Orionids observed between 2007 and 2010). The peak ZHR reached 135 ± 16. Updated information on the expected time and rates of the shower is provided through the annual IMO Meteor Shower Calendar.

Eta
Aquariid outbursts occurred in 74 BCE, 401, 443, 466, 530, 839, 905, 927, and 934. The Eta Aquariids were the first meteor shower linked to Halley's comet and are usually two to three times stronger than the October
