Abstract: An overview of the radio observations during August 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 August 2025.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
Local interference and unidentified noise remained quite limited, and some lightning activity was only recorded on 5 days. There were however frequent solar eruptions, mostly of Type III.
The highlights of the month were, of course, the Perseids, which, as every year, produced numerous long-lasting reflections. After a start-up period with increased activity in the first part of the month, the shower reached its forecasted maximum on August 12–13, after which activity quickly declined.
Over the entire month, 51 reflections longer than 1 minute were recorded here. Figures 3 to 44 show a selection, along with some other interesting images. 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.
