Abstract: An overview of the radio observations during October 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 October 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 3 days lightning activity was detected.
While not spectacular, the Orionids remained the most eye-catching shower of the month, culminating on October 22nd. Several minor showers also produced some long-lasting reflections, i.e. around October 15th.
This month 16 reflections longer than 1 minute were observed here. A selection of these, together with some other interesting reflections are shown in Figures 3 to 11.
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, please let me know: I’ll send you the underlying Excel files and/or plots. Please send me an e-mail; felix.verbelen at skynet.be.
