Abstract: An overview of the radio observations during May 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 May 2026.

The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:

Local interference and unidentified noise remained very limited, but lightning activity was recorded on 6 days, being intense on May 13 and 30. There were also quite numerous, fairly strong solar flares, mostly type III.

The main highlights of the month were the Eta Aquariids around May 6, though they were less prominent this year than in previous years, especially regarding long-duration reflections. There was also increased activity around May 20, likely caused by the epsilon Aquilids.

Furthermore, closer analysis of the counts reveals various minor showers.

Over the entire month, 10 reflections lasting longer than 1 minute were observed here. A selection of some notable or strong reflections is shown in Figures 5 to 25. 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.
