Abstract: An overview of the radio observations during March 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 March 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 significant lightning activity was recorded. However, there were several fairly strong solar flares, such as on March 16 between 12h00m and 13h00m UT (Figure 3).
As expected, meteor activity remained very low this month. However, the daily counts of overdense reflections showed a clear structure, with peaks on March 6 and March 21. Due to the low number of registrations, caution is advised when interpreting the results, and further research is required.
Only on March 14 was a reflection of approximately 1 minute recorded. A selection of some notable or strong reflections is shown in Figures 4 to 10. 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.
