Abstract: An overview of the radio observations during September 2026 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 September 2026.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
Local interference and unidentified noise remained very limited, and no lightning activity was recorded this month. The first few days of the month saw regular strong solar outbursts, mostly of type III, though their frequency decreased significantly during the second half of the month.
There were no truly striking meteor showers during this month except on September 10 (September epsilon Perseids), but activity nevertheless remained interesting, featuring both a number of minor showers and a fair number of long reflections on September 15 (solar longitude = 172°).
Over the course of the month, 20 reflections longer than 1 minute were recorded here. A selection of these, along with several other interesting reflections, is shown in Figures 3 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.
