TL;DR
This study reports VLF radio observations of the 2002 Leonid Meteor Shower from Kolkata, identifying signal patterns and peak activity times using a specialized antenna during the event.
Contribution
First VLF observational data of the Leonid Meteor Shower from Kolkata, highlighting signal characteristics and temporal activity patterns.
Findings
Peak VLF activity at 3h58m UT on Nov 19, 2002
Detection of beadlike and exponentially dropping signals
Pre-peak signals observed on Nov 18, 2002
Abstract
Using a Gyrator-II Loop antenna tuned at 19.0Khz, we monitored the meteor shower during 17-24th November, 2002. We observe the primary peak at 3h58m (UT) on the 19th of November, 2002. We distinctly observed several `beadlike' and `exponentially dropping' signals. The `beadlike' signals were more in abundance on the 18th of November, 2002, one day prior to the actual encounter.
