Archived Whistler Events Whistler events detected by my system are eventually moved from "Current VLF Events" to the Archive, and rendered here. The last time this archive was regenerated was Tue 21 Jan 2025 07:01:31 PM UTC

The following graphs show the total detection counts of whistlers by day, and time of day, between 2014 and 2024. The total number is whistler events in the archive is 2516 (though really a bit higher, as there are many cases of multiple whistlers per 'event').
