Abstract: An overview of the radio observations during November 2021 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 November 2021.

The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:

Local interference and unidentified noise remained moderate during most of the month and only on 4 days weak lightning activity was detected.

This month 18 reflections longer than 1 minute were observed here. A selection of these is shown in Figures 3 to 12.

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.
