Geminids 2010: visual data quicklook

Introduction

This page shows automated results of the Geminids 2010, based on visual observations by volunteers astronomers collected through the report form of the International Meteor Organization (IMO). The information on this page is generated automatically; for scientific use please refer to manual analyses published in scientific journals (such as WGN).

Activity profile

The graph below shows the ZHR (Zenithal Hourly Rate), which is the number of meteors an observer would see under a very dark sky with the radiant of the shower in zenith.
ZHRmax = 57 based on 1072 Geminids reported in 215 intervals, assuming population index r = 2.0
