Abstract: An overview of the radio observations during December 2024 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 2024.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
Local interference and unidentified noise remained weak to moderate, and lightning activity was only detected on December 22nd.
The highlights of the month were, of course, the Geminids (Figure 3), while the Ursids were clearly present on December 22nd. An increase in reflections longer than 10 seconds was also noted on December 24th. In addition, there were some minor showers, especially at the beginning of the month.
This month, 9 reflections longer than 1 minute were observed here, spread throughout the month. A selection of these, along with some other interesting reflections is included (Figures 4 to 15). More of these are available on 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.
