May 6 means a morning, not a peak minute
The IMO table lists activity from April 19 to May 28 and gives May 6 as the maximum date without a peak hour. Plan for the pre-dawn darkness around that date, when Aquarius has risen but morning twilight has not begun. A second morning is useful insurance against cloud.
The ZHR benchmark of 50 assumes a dark sky and favorable geometry. Aquarius climbs much higher from southern latitudes, which is why southern observers usually get the stronger view.
Halley’s debris meets Earth twice each year
The Eta Aquariids come from material associated with comet 1P/Halley. Earth crosses related debris again in October, when the different approach direction produces the Orionids and a radiant in another constellation.
Eta Aquariid particles enter near 65 kilometres per second. The comet need not be visible or even nearby for old material along its orbit to make a shower.
A low radiant changes the trail you see
At northern latitudes, find an open eastern horizon and begin before dawn. A meteor arriving while the radiant is low can skim a long atmospheric path, producing an earthgrazer that stretches across much of the sky.
Keep Aquarius away from the center of your view and record full paths. Their backward directions reveal likely shower members more reliably than brightness alone.
