An overview of the radio observations during October 2019 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 2019.

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

N(h) = n(h-1)/4 + n(h)/2 + n(h+1)/4

During this month our registrations were quite often affected by moderate local interference and on 4 days by lightning activity, but no observed “sporadic E” (Es).
The automatic countings were manually corrected in order to eliminate the effects of the disturbances.

Some screen-dumps of a selection of eye-catching long duration reflections are displayed (Figures 3 to 15).
