An overview of the radio observations during November 2020 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 2020.

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 no lightning activity was detected.

The meteor activity was surprisingly strong this month, especially on November 4th (solar longitude 220°) and from November 15th till the 21st (solar longitude 233° till 240°), these periods being clearly linked to the Taurid complex and the Leonids. It is interesting to notice that the strongly increased activity is only evident for long overdense reflections and hardly seen in the underdense figures.

This month 34 reflections longer than 1 minute were observed here. A selection of these, together with some other interesting reflections are included (Figures 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 and 19).

If you are interested in the actual figures, or in plots showing the observations as related to the solar longitude (J2000) rather than to the calendar date. I can send you the underlying Excel files and/or plots. Please send me an e-mail:  felix.verbelen at skynet.be.
