Abstract: An overview of the radio observations during October 2022 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 2022.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
Local interference and unidentified noise remained moderate to low during most of the month. Lightning activity was observed on 5 days. Especially during the first half of the month there were several intense solar eruptions causing sometimes considerable noise (Figures 3 and 4) while solar activity remained quite low on 49.99 MHz during the second half of the month.
On October 20th, the Orionids reached here their maximum activity, showing a clearly increased number of overdense reflections, best seen in the daily totals. Over the entire month, 18 reflections longer than 1 minute were registered here.
Attached are selections of long reflections (Figures 5 to 19) and of “epsilons” (Figures 20 to 31).
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.
