An overview of the radio observations during March 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 March 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 quite some local disturbances, but no registered “sporadic E” (Es) nor light activity. As expected, general activity was low, without eye-catching showers, but with nonetheless several interesting minor showers as shown by the graphs of overdense reflections.
Attached are also a few examples of the strongest reflections (Figures 3, 4, 5, 6 and 7).
