An overview of the radio observations during January 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 January 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 there few local disturbances, no registered “sporadic E” (Es) nor was there lightning activity.
Highlights of the month were of course the Quadrantids. For this I published an overview earlier in MeteorNews. The rest of the month was fairly calm, but with nevertheless a number of nice smaller meteor showers (to be analysed in detail) and with a few spectacular “radio fireballs” (see Figures 3, 4, 5 and 6).
If you are interested in the actual figures, please send me an e-mail: felix.verbelen at skynet.be.
