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

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

Local interference and unidentified noise remained very limited, but severe lightning activity was recorded on 11 days. On 6 of these days, this also occurred in the immediate vicinity of the beacon, which made the automatic counting of meteors during those periods very difficult (Figure 3). The automatic counts of “all” meteors were therefore manually corrected for those periods. There were also numerous strong solar flares, mostly of type III, and occasionally type II.

The main highlights of the month were the daytime showers, primarily the Arietids, but smaller showers such as the zeta Perseids and others also made the month particularly interesting.

Over the course of the entire month, 9 reflections lasting longer than 1 minute were observed here. A selection of these, along with several other interesting reflections, is shown in Figures. 4 to 18. 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.
