Abstract: An overview of the radio observations during March 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 March 2022.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
On 1 and 4 March there were interruptions due to maintenance work near our beacon, so data for those periods are missing.
Local interference and unidentified noise remained low for most of the month apart from sometimes strong noise caused by solar eruptions (Figure 3), but this was of course interesting in itself.
No lightning activity was recorded during this the month. As expected, overall shower activity remained low, with no real highlights, but there were some interesting minor showers such as the Zeta Cygnids on March 24th.
Only 4 reflections lasting more than 1 minute were observed this month, 2 of which were rather faint. (Figures 4 to 7).
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.
