An overview of the radio observations during February 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 February 2020.

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 there were few local disturbances, no registered “sporadic E” (Es) but quite strong light activity on several days (especially on 4, 10, 25 and 26 February).

This month there were no eye-catching showers, but several minor ones showed interesting activity, as can bee seen in the graphs of overdense reflections.

Attached are also a few examples of the strongest reflections (Figures 3 to 6).
