An overview of the radio observations during September 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 September 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, but no “sporadic E” (Es) or lightning activity.
The automatic countings were manually corrected in order to eliminate the effects of the disturbances.

The registrations show no great outbursts this month, but nevertheless enhanced activity around September 10th and a number of minor showers,
with also a number of eye-catching long duration reflections (Figures 3 to 16).
