An overview of the radio observations during September 2018 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 September 2018.
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 fortunately almost free of strong local interference, there was no registered “sporadic E” (Es) and only on September 5th there were thunderstorms with strong lightning activity.
The meteor activity was, as expected, fairly quiet with only modest meteor showers, but with nonetheless a number of fairly spectacular “fireballs” in the period 7-18 September (attached are some examples).
