ETA · RADIANT
Eta Aquariids RA 22h 24m · DEC -1.4 deg

A major fast shower with a broad elevated-rate interval in early May; radio monitoring is effective despite the low northern radiant.

A broad ecliptic radiant region rather than a true shower. It provides calendar context for weak near-ecliptic activity outside the Taurid season.

Shower calendars and radiant positions provide astronomical context only. They do not identify the cause of an individual radio record. Visual ZHR is not a radio echo rate. Read the identification and limitations note .

Radiant positions are interpolated from the IMO 2027 Meteor Shower Calendar. The broad Antihelion Source, when shown, is a diffuse radiant region and not a true meteor shower.

Receiver activity, not visual ZHR. Rates use measured observing time.
