We present the report of iota-Draconids 2002 visual data totaled by the Nippon Meteor Society.
Adopted data is personal observation, radiant height >10deg, limiting magnitude>4.5mag. and clouds <50%.
Zenithal hourly rate(ZHR), which are we visible meteors on the ideal condition, is calculated from reported data by using luminous index = 2.5 and radiant height correction = 1/sin(RP.H) that based on the method of International Meteor Organization(IMO).
<ZHR Err.> on the table is mean ZHR division by square root of total observers' number.
