Caught sight of this today. At first I thought it was my kit but the QO100 WebSDR showed the same. It started before 10:29 UTC (the first photo, below was taken at 10:29) to 11:37 UTC (it went on after that and I did not record the end). 10:29 UTC, sounded a bit like a fast data transmission. 10:30 UTC, a short burst of the same followed by a much wider band transmission. 10:31 UTC and something tuning up perhaps? The signal strength plot (no screenshot) looked like a strong carrier and lots of harmonics, kind of like you see when keying a handled near an SDR. This one definitely sounded like a data transmission. I can’t remember the mode but lots of tones and quite ‘musical’.
