An overview of the radio observations during October 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 October 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 only on 3 days lightning activity was detected.

Due to a technical problem the beacon power was reduced from 12 till 17 October. This is clearly seen in the plot of “all” reflections which are counted automatically, but hardly affected the manually counted overdense and longer reflections.

Although the Draconids and Orionids often produce a nice show, this time they were hardly eye-casting. The most striking activity increase happened on October 16th (solar longitude 203.1°) with a clear increase of  reflections longer than 10 seconds.

This month 15 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 and 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. I can send you the underlying Excel files and/or plots. Please send me an e-mail:  felix.verbelen at skynet.be.
