Abstract: An overview of the radio observations during September 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 September 2022.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
On many days, especially during the evening and night, radio reception was disturbed by unidentified noise. In addition, sometimes intense lightning activity was recorded on 12 days and also solar eruptions caused strong noise on several occasions.
Manual counting of the reflections remained possible despite these disturbances, but the automatic counts were quite difficult and had to be corrected manually.
There were hardly any real eye-catchers this month, but around September 9, 18, 25 and 29 there were clearly structured increases of overdense reflections longer than 10 seconds, which is best seen in the daily totals.
Over the entire month, 15 reflections longer than 1 minute were registered here. attached are selections of long reflections (Figures 5 to 14) and of “epsilons” (Figures 15 to 30).
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.
