Abstract: An overview of the radio observations during October 2024 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 October 2024.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
Local interference and unidentified noise remained generally low, and no lightning activity was recorded this month.
During the night of October 10–11, visual observers could admire a rather strong display of the aurora borealis, which was also detected on the frequency of our beacon. Figure 5 is a recording between 2024 October 10, 23h00m UT and 2024 October 11, 02h00m UT.
The activity of both the Draconids and Orionids was rather limited this year, although there was an increase in long-duration reflections (> 1 minute) around the Orionid maximum on October 22–23.
Further investigation also reveals various interesting minor showers, the most notable around October 29 between 18h and 24h UT. The increased activity consisted mainly of rather weak underdense reflections.
Over the entire month 27 reflections longer than 1 minute were recorded here. A selection of these, along with some other interesting reflections is included (Figures 6 to 23). More of these are available on 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.
