Abstract: An overview of the radio observations during December 2025 is given.
The graphs show both the daily totals (Figure 1) and the hourly numbers (Figure 2) of “all” reflections counted automatically, and of manually counted “overdense” reflections, overdense reflections longer than 10 seconds and longer than 1 minute, as observed here at Kampenhout (BE) on the frequency of our VVS-beacon (49.99 MHz) during the month of December 2025.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
No lightning activity was detected, and local interference and unidentified noise remained low throughout the month.
The highlights were, of course, the Geminids, which reached their peak on December 13–14; the long-duration ‘overdense’ echoes clearly peaked later than the ‘underdense’ ones. The Ursids were also interesting, with their maximum on December 22nd. Attached you will find a few screenshots of both the Geminids (Figure 3) and the Ursids (Figure 4).
On December 26th, there was another minor surge of ‘overdense’ reflections, likely the omega and sigma-Serpentids.
Throughout the entire month, 7 reflections lasting longer than one minute were recorded here. A selection, along with a few other interesting reflections is shown in Figures 7 to 15. Many more are available upon request.
In addition to the usual graphs, you will also find the raw counts (subject to strict reservations as previously said) in cvs-format from which the graphs are derived. The table contains the following columns: day of the month, hour of the day, day + decimals, solar longitude (epoch J2000), counts of “all” reflections, overdense reflections, reflections longer than 10 seconds and reflections longer than 1 minute, the numbers being the observed reflections of the past hour.
