Geminids 2014: visual data quicklook

Introduction

This page shows automated results of the Geminids 2014, based on visual observations reported by citizen scientists 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). Send your feedback regarding this page to Geert Barentsen.

Note that the data will finally go into the Visual Meteor Database (VMDB) with manual inspection and rectifications. We are curretly completing the files of 2008-2011. The VMDB is an enormous project - any help will be greatly appreciated.

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 = 253 based on 12110 Geminids reported in 1124 intervals, assuming population index r = 2.0
