Abstract: An overview of the radio observations during July 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 July 2025.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
Weak to moderate lightning activity was detected on 7 days, and strong solar flares, mostly of type III, occurred almost daily.
Several showers were active this month, with a notable increase in long-duration reflections, especially during the last few days of the month. A total of 14 reflections lasting more than 1 minute were observed, 7 of which occurred from July 27th to 30th. A selection of these, along with a few other interesting recordings is included (Figures 3 to 22).
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.
