Abstract: An overview of the radio observations during May 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 May 2022.
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, but observations were sometimes difficult due to strong lightning activity (on 9 different days) and near daily powerful solar eruptions (see Figures 3, 4 and 5). This solar activity was of course interesting in itself.
The general meteor activity was quite high, with the eta Aquariids in the first days of the month, and throughout the month mainly daytime showers. In addition, on the 31th there was the predicted outburst of tau Herculids.
This month, 22 reflections lasting more than 1 minute were observed. A selection of SpecLab images is shown in Figures 6 to 19.
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.
