Leonid Meteor Show detection by radio scatter at Lichfield Radio Observatory (LRO) 17-18/11/2025
Some (not so great)evidence of Leonids detected at LRO on 143.050MHz, Graves. See increased intensity in early hours of 18/11/2025. However, this is nothing like the intensity of meteors in…
List of meteor showers
Here’s a practical “all the ones that matter” list, with 2025 peak nights and typical peak rates (ZHR under dark, clear skies). For the exhaustive working list (including many minor/variable…
Range of sizes of meteors coming into Earth’s atmosphere
Meteors vary enormously in size, depending on the original meteoroid (the solid body before it enters Earth’s atmosphere). Here’s a breakdown by category: Type Typical Size (Diameter) Description Micrometeoroids <…
Using digital TV signals for radio meteor scatter
This is very relevant for modern meteor detection, since many traditional continuous-wave (CW) beacons have gone silent while digital TV (DTV) and FM broadcast transmitters now fill the VHF/UHF spectrum.…
What is Radio Meteor Scatter
Radio meteor scatter is a radio propagation phenomenon where radio waves are reflected or scattered by the ionized trails left behind by meteors as they burn up in the upper…
Head and trail echoes in radio meteor scatter
In meteor scatter, the head echo is the radar reflection from the plasma region immediately surrounding the meteoroid itself as it travels through the atmosphere — essentially, the “glowing ball”…
Dedicated software options for amateur ham radio meteor scatter
Here’s a breakdown of software options (and their pros/cons) for meteor-scatter / forward-scatter / meteor radio detection, along with which operating systems they support (or are known to run on).…
Moxon dimensions for radio scatter at BAA Radio Beacon and GRAVES
Here are practical, build-ready Moxon dimensions for the two bands. I’m using standard Moxon A-E notation (A = overall width; B = tip gap between element ends; C = feedpoint…
Meteor Pings recorded at LRO (video created from observations prior to 25/8/2025)
The link below plays an mp3 file of the sounds (pings) from meteor observations at LRO (composed of number of events over couple days with gaps removed). If you’ve never…
