First, not starting any arguments. Second the chart is over a 48 Hr period, sample at 5 minutes intervals. Both my stations had basically shown the same increase and decrease for each wave. And according to the following link: https://twitter.com/akrherz/status/1482436390105272320, the direct wave passed through the area around 15:00 UTC (10:00 AM) and the second wave (much strong) from the opposite direction passed through the area around 05:10 UTC (12:10 AM) Jan 16.
