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.
