June iota Pegasids
Measurements from the IAU Meteor Data Center. Each parameter set describes an observation campaign; values and proposed parent bodies may differ between sets.
An activity peak is expressed as solar longitude, not a guaranteed calendar date or observing forecast. Radiant coordinates and orbital elements are reported as supplied by the source. Missing values are not reported; these data do not predict an hourly meteor rate.
