An overview of the radio observations during July 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 July 2018.

On several days automatic counts were quite problematic due to (local) interference, thunderstorms (6 days with lightning activity) and sometimes strong sporadic E (10 days with Es).
Strong lightning activity in the direction of our VVS-beacon made it even impossible to manually count underdense meteors on 20180727 from 16:00 to 20:00 UT; in addition, our beacon was “OFF” on 20180711 (18:02-19:06 UT) and on 20180728 (02:19-12:04 UT), so that data for those periods are missing.

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
