My image contains interference from lightening strikes. I have likely seen lightening interference before, but it a first for me to be able to confirm it. The sky above our house was blue but to the East I could see dark storm clouds. Each time the clouds flashed orange, even though they they were too far for thunder to be audible, I could 'hear' the strikes as bursts of radio noise. I have uploaded a photo of the waterfall display clearly showing a horizontal line of interference from a lightening strike. In the decoded imagery, the lightening is visible as broken lines, not more than a one to two pixels wide. Given the position of NOAA-19, the storm must have been between me and the it. I should note that that last photo of the storm clouds almost overhead was taken more than 10 minutes after I had finished recording and packed away my antenna. Under no circumstances is it wise to point an antenna in the proximity of a storm. I admit that the speed of the storm clouds surprised me. As they approached, a warm wind got up and shook trees on the street below, while I watched neighbours rush to closed windows on flapping curtains. The change in light levels was dramatic too. In less than half an hour, day turned to night.
