Abstract: An overview of the radio observations during October 2023 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 2023.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
Local interference and unidentified noise remained moderate to low for most of the month, and solar activity also caused only limited periods of increased noise.
Lightning activity was observed on 2 days.
The Orionids were especially active during the period October 19–28, with a clearly increased number of overdense and long reflections.
Over the entire month, 20 reflections longer than 1 minute were recorded. A small selection of these, along with some other interesting reflections is included (Figures 3 to 17). Many more of these are available on request.
In addition to the usual graphs, you will also find the raw counts 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.
