An overview of the radio observations during September 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 September 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. No lightning activity was detected.
During this month no real eye-catching shower was active, but nonetheless the activity remained interesting, showing both a number of minor showers, a fair number of long reflections, and a gradual activity increase towards the end of the month.
This month 12 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 and 12).
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.
